}}The version of '''''[[Counter-Strike: Condition Zero]]'' designed by [[Gearbox Software]]''' was the second of four major iterations of the game in the game's convoluted development history.

This iteration of the game was originally more reminiscent of the version of ''Condition Zero'' developed by [[Turtle Rock Studios]], having an arcade-like take on the single-player experience. Later during development, the design for the single-player component was changed and it became more similar to the version designed by [[Ritual Entertainment]] which was released separately as ''[[Counter-Strike: Condition Zero Deleted Scenes]]''.

Despite essentially getting canned, many of the concepts and assets were used in future development of both ''[[Counter-Strike]]'' and ''[[Counter-Strike: Condition Zero]]''.

==Development==
[[Randy Pitchford]], president of [[Gearbox Software]], had been talking about the possibility of working on a ''[[Counter-Strike]]'' related project with [[Valve Software]] for quite a while, but other commitments had kept Gearbox from working on such a project.<ref name="gamesdomain_2001" /> However, in May 2001 Gearbox was just about to finish development on ''[[wikipedia:Half-Life: Blue Shift|Half-Life: Blue Shift]]'' and wrap up work on the [[wikipedia:Playstation 2|Playstation 2]] port of ''[[Half-Life]]'', meaning that the bandwidth needed to manage such a project was finally becoming available.<ref name="actionvault_int">[https://web.archive.org/web/20020802004438/http://actionvault.ign.com/features/interviews/cscz.shtml Action Vault - Counter-Strike: Condition Zero Interview].

Gearbox and Valve quickly reached an agreement whereby further primary development of ''Condition Zero'' would be handled by Gearbox.<ref name="pczone_0112" /><ref>[https://web.archive.org/web/20011214084403/http://www.mgon.com/interviews.phtml?id=104671 MGON  - Randy Pitchford Interview].

To assist in the creation of new content, several well-known designers and modders were recruited from the community. The level designing department at Gearbox was strengthened in June by the recruitment of several prominent community designers, including [[David Johnston]], [[Christopher Auty]] and [[Alexander Manilov]].<ref name="gamespy_0109">[https://web.archive.org/web/20011204193745/http://www.gamespy.com/previews/september01/condzero/ GameSpy.com - Preview: Counter-Strike: Condition Zero (PC)].

[[File:Cscz stephenpalmer.jpg|thumb|left|Project manager [[Stephen Palmer]] at work]]
By November 2001, the game was rapidly approaching alpha stages.<ref name="avault_czfeat" /> The amount of maps was specified to be between 20 and 30, divided into five different campaigns.<ref name="avault_czfeat" /><ref name="intelgamer" />

In December, the game was stated to be feature complete.<ref name="halflife_nu" /> Now the amount of maps had been locked down to 25, divided into six campaigns.<ref name="gamespy_0112" /> Most of the maps were finished by this time with only minor polishing work left to do.<ref name="halflife_nu" /> This meant that many of the map designers recruited from the community had finished their contribution to the project by this stage and left the development team.<ref name="linkedin_manilov" /><ref name="linkedin_ncoombe" />

On February 12, 2002 it was announced that the release of the game would be delayed until Q2 2002.<ref>[http://www.gamezone.com/news/counter_strike_condition_zero_to_ship_worldwide_q2_2002 Press Release - Counter-Strike: Condition Zero To Ship Worldwide Q2 2002]</ref> This delay was accounted to wanting to make the AI act as realistically as possible.<ref name="gamehelper_gdc" /> A factor that may also have contributed to this was the expanded design ambitions of the game, which included raising the number of objectives per map to 12.<ref name="avault_update">[https://web.archive.org/web/20020603175951/http://www.avault.com/news/displaynews.asp?story=4292002-8364 The Adrenaline Vault | News | Condition Zero Update].

In mid-February, Gearbox Software president Randy Pitchford and vice president Brian Martel visited Europe in order to promote the game. In Europe, the game would appear at its first major media event, the Vivendi Universal Games Faire held on February 19 in Paris, France.<ref>[http://www.4players.de/4players.php/dispbericht/Allgemein/Special/2364/988/2/Vivendi_Universal_Games_Faire_2002.html 4Players.de - Special: Vivendi Universal Games Faire 2002]</ref><ref>[https://web-beta.archive.org/web/20020606164820/http://www.vivendiuniversalpublishing.com:80/english_version/press_releases/vup_020219_monster_force.htm Press Reelase - Universal Interactive launches Monster Force, a new multi-player handheld game adventure].

[[File:Cscz_gearbox_randy_gdc2002.png|thumb|left|Randy Pitchford presenting the game at Game Developers Conference]]
Shortly after Game Developers Conference, a major change in direction occurred in the development of the game. [[Valve Corporation|Valve Software]] no longer felt like the arcade-like single-player approach was the right direction for the title and a decision was made to change the narrative portion of the game into a more traditional linear shooter.<ref name="shacknews_ritual" /><ref name="csczvault_joshint" /> This change was made because the narrative of the original single-player mode was not good enough.<ref name="pczone_0208"/> In late April 2002, it was teased that this entirely new single-player experience would be revealed at E3 2002.<ref name="avault_update" />

As promised, the game was present at E3 in May 2002 and was demonstrated in NVIDIA's suite.<ref>[https://web.archive.org/web/20020609022517/http://cs-conditionzero.com/pr_01.html Press Release - NVIDIA and Valve Demonstrate Counter-Strike: Condition Zero at E3 2002]. Archived from the original on 2002-06-09.</ref> At the show, a demo was showcased which focused on pushing the new single-player experience of the game.<ref name="gamehelper_e3" /> The single-player component had evolved from the arcade inspired experience to a more traditional single-player experience complete with scripted sequences.<ref name="csczvault_joshint" /><ref name="actionvault_int" /> This mode was in many ways reminiscent of [[Ritual Entertainment]]'s version that was eventually released as ''[[Counter-Strike: Condition Zero Deleted Scenes]]''.<ref name="csczvault_joshint" /> Another delay was also announced, as the release of the game had been pushed to fall 2002.<ref name="actionvault_intelligence" /> This would end up being the last major media event that ''[[Counter-Strike: Condition Zero]]'' was presented at when [[Gearbox Software]] was still in charge of development.

In July 2002 [[Gearbox Software]] ceased development on ''[[Counter-Strike: Condition Zero]]'' and development was overtaken by [[Valve Corporation|Valve Software]].<ref name="plan_pitchford">[https://www.bluesnews.com/cgi-bin/finger.pl?id=293&time=20021206203741 .plan File for Randy Pitchford]</ref> Gearbox left the project because it wanted to "[refocus] its efforts on future technology and more interesting and innovative game play".<ref name="plan_pitchford" /><ref>[http://www.ritualistic.com/forums/showpost.php?p=148509&postcount=7 Ritualistic Forums - View Single Post (by BrushBaron) - Re: To: Any Ritual team members Re: Thanks]</ref>

The decision by Gearbox Software to leave was likely fueled by displeasure following Valve's decision to change the single-player to a more linear design, an approach which Gearbox had previously called "boring"<ref name="gamespot_video" />. This change in single-player design also meant prolonging the development of the title and the fact that Gearbox had other lucrative projects (including PC ports of [[wikipedia:James Bond 007: Nightfire|James Bond 007: Nightfire]] and [[wikipedia:Halo: Combat Evolved|Halo: Combat Evolved]]) under development could have spread their manpower too thin.

On August 1, 2002, Valve Software released an official trailer for the game based on the demo that had been showcased at E3.<ref name="csn_trailer">[https://web.archive.org/web/20030423195239/http://csnation.counter-strike.net/comments.php?id=4898 CS-Nation - new cs: cz movie].

==Game modes==
===Single-player, first iteration===
{{quote|The fundamental game design is completely different than anything we've seen in a first person action game so far - it's more akin to [[wikipedia:Tony Hawk's Pro Skater 3|Tony Hawk's Pro Skater 3]], than to, say, [[wikipedia:Half-Life: Opposing Force|Opposing Force]].|Randy Pitchford<ref name="lonegamers">[https://web.archive.org/web/20020811131935/http://www.lonegamers.com/content.cgi?mod=Interview&id=2719 Lone Gamers: Condition Zero].

From the time [[Gearbox Software]] started developing the single-player mode until around March/April 2002, the main single-player mode had a very non-linear arcade inspired design which was in many ways reminiscent of the [[Tour of Duty]] game mode that was developed by [[Turtle Rock Studios]]. The designers at Gearbox Software felt that going for a standard linear design for the single-player mode would have been an easy and boring route, so they wanted to try something new and exciting and therefore went for a more arcade like approach.<ref name="gamespot_video" />

Originally, separate single-player campaigns were planned for both the Terrorists and Counter-Terrorists,<ref name="ign_interview" /> however a decision to make the campaign Counter-Terrorist only was made relatively quickly.<ref name="avault_czfeat" /> The general design of the single-player game took inspiration from console titles such as ''[[wikipedia:Tony Hawk's (series)|Tony Hawk's Pro Skater]]'' and ''[[wikipedia:Gran Turismo 3: A-Spec|Gran Turismo 3: A-Spec]]''.<ref name="gamespy_0112" /> In the campaign, the player took the role of a [[Counter-Terrorists|Counter-Terrorist]] squad leader, embarking on various missions.<ref name="cgonline" />

When starting the singe player mode, a player profile had to be created first.<ref name="gamespy_0112" /> After this, the player could choose between the five different Counter-Terrorist factions.<ref name="gamespy_0112" /> Each faction had an exclusive weapon that could only be unlocked for other factions after completing the game with the faction for which the weapon was exclusive.<ref name="ferrago_preview" /> For example, completing the single-player mode with the [[Spetsnaz]] faction would unlock its exclusive weapon, the [[AK-47]], for all the other factions,<ref name="gamespy_0112" /> and completing the game with the [[GIGN]] faction would unlock the [[FAMAS]].<ref name="gamesweb" /> Each faction also had exclusive characters, with the best sniper being a [[SEAL Team 6]] operative and the best demolitions expert a [[SAS]] operative.<ref>[https://web.archive.org/web/20020429202832/http://www.playerofgames.com/articles/index.php?id=35 Player Of Games - Condition Zero interview with Randy Pitchford director of Gearbox software]. Archived from the original on 2002-04-29.</ref> Completing all objectives with all Counter-Terrorist squads would give the player special, undisclosed, rewards.<ref>[https://web.archive.org/web/20020205035646/http://www.zerogamers.com/zt/pitchford.htm Zero-Tolerance - Randy Pitchford Interview]. Archived from the original on 2002-02-05.</ref>

After choosing a faction, the player would land in a virtual ready room with multiple choices.<ref name="tiscalicz_randyint" /> These were:
*'''Personnel''' - Here a player could hire additional squad members for a maximum of four (including oneself).<ref name="gamespy_0112" /> Initially, the player couldn't afford hiring any squad members, thus the first missions were undertaken alone.<ref name="firingsquad_gdc" /><br />Each squad member had skills which affected their performance. There were 10 different skills in total,<ref name="pczone_0204" /> with skill levels ranging from level 1 up to level 5.<ref name="gamespy_0112" /> When hiring squad members, characters could be chosen from a pool of over 100 different possibilities with each character having an unique combination of skill levels.<ref name="gamespot_gdc" /> Characters with better initial skills would cost more to hire.<ref name="pczone_0112" /> For a cost, it was possible to train squad members at the personnel screen,<ref name="gamespy_0112" /> but only five of these ten skills were exposed to training.<ref name="pczone_0204" /> (The improvable skills were small arms, rifle, demolitions, awareness and tactics.<ref name="gamehelper_gdc" />) This meant that some bots were inherently better at certain tasks, e.g. sniping, than others.<ref name="pczone_0204" /><br />In an effort to make players feel more attached to their teammates, each squad member would also have a unique name, head model, personality and and voice.<ref name="cgonline" /><ref name="ign_interview" /><ref name="pczone_0112" />
*'''Arsenal''' and '''Load out''' - At the arsenal screen, one could use cash earned from completing missions for purchasing new weapons and armor to a central inventory.<ref name="gamespy_0112" /> A rifle could cost over $2000.<ref name="gamestar_0204" /> Purchased weapons, armor and other equipment were then equipped at the load out screen.<ref name="gamespy_0112" /> Each squad member could wear two firearms (primary and secondary), a kevlar, a helmet and up to three grenades.<ref name="gamestar_0204" /><ref name="gamesweb">[http://www.gameswelt.de/counter-strike-condition-zero/preview/counter-strike-condition-zero,3450 Gameswelt - Counter-Strike: Condition Zero - First Look]</ref> In contrast to traditional ''Counter-Strike'' maps, there were no buy zones in the maps themselves and squad members were equipped with the arsenal specified at the load out screen.<ref name="avault_czfeat" />
*'''Missions''' - This would take you to a mission map overview from where a mission could be started.<ref name="gamespy_0112" /><ref name="gamehelper_e3" />

Before being able to play any of the actual missions, a [[Range|training mission]] had to be completed.<ref name="gamestar_0204" /> The game would determine the difficulty level of the campaign based on how the player performed in the training.<ref name="gamestar_0204" />

Initially, the missions or maps were divided into four campaigns based on themes (arctic, urban, desert and jungle).<ref name="homelan_randy" /><ref name="gamehelper_interview" /> A later iteration of the game had the maps divided into six different campaigns, which were the jungles of South America, arctic Russia, urban Europe, Far East Asia, the United States and the Middle East.<ref name="pczone_0204" /> These campaigns could be played freely in any order.<ref name="firingsquad_gdc" /> Each map could be played in three different modes and the objectives for the map were unique to the combination of map, mode and faction.<ref name="tiscalicz_randyint" /><ref name="gamespy_0112" /> The game modes that the maps could be played under were the following:
*'''Narrative mode''' - This was the main story mode of the campaign, which was the only mode necessary to complete to play through the game.<ref name="pcgames_magazine" /> (This probably refers to the unlocking of squad specific weapons.) When staring a map in this mode, the player would be presented with an intelligence overview providing mission instructions.<ref name="avault_czfeat" /> As the name suggests, this mode also provided the story for each mission giving players a sense of purpose and incentive to succeed.<ref name="gamestar_0204" /><ref name="pczone_0112" /> Originally there were three objectives for each map in this mode,<ref name="gamespy_0112" /> but the amount of objectives was later raised to four.<ref name="gamespot_gdc" /> Examples of objectives in this mode were:<ref name="gamespot_gdc" /><ref name="gamespy_0112" />
**Rescue hostages
**Defuse bomb
**Plant surveillance equipment<ref name="pczone_0204" />
**Eliminate the terrorist force
**All teammates must survive
**Win in under 3 minutes
*'''Endurance mode''' - This mode was about survival and one would play without other squad members.<ref name="gamespot_gdc" /><ref name="gamestar_0204" /> The tasks in this mode were very varied, examples include:<ref name="gamespy_0112" /><ref name="gamespot_gdc" /><ref name="gamestar_0204" />
**Survive a specific amount of enemy waves for a certain amount of time
**Eliminate 8 enemies and survive for 5 minutes
**Reach the level exit
**Collect specific objects scattered around the map (e.g. suitcases with confidential information)
*'''Challenge mode''' - When playing this mode, the game was made more difficult by imposing restrictions for completing the map. These included a very short time limit, restrictions to certain weapons or being required to achieve a certain accuracy percentage.<ref name="gamespy_0112" /> Examples of such restrictions include:<ref name="gamespot_gdc" /><ref name="gamespy_0112" />
**Win in under 90 seconds
**Win the map using only pistols
**Finish the map without reloading your weapon
**Achieve an accuracy percentage of 50 or higher
**Eliminate 3 enemies with a knife<ref name="gamespot_video" />
**Rescue hostages without firing a weapon<ref name="halflife_nu">[https://web.archive.org/web/20020105164439/http://www.halflife.nu/artiklar/?id=46 Halflife.nu - CS:Condition Zero interview]. Archived from the original on 2002-01-05.</ref>

For each objective completed, the player would receive a certain amount of money (typically around $600<ref name="gamestar_0204" />) that could be used for purchasing equipment or training squad members. Also, while the campaigns could be played in any order, unlocking the next map in a campaign required a specific amount of total earnings.<ref name="intelgamer" /> This usually meant completing at least two objectives per mission.<ref name="gamespy_0112" />

The game would autosave after each completed mission, but no saving was possible while playing a mission.<ref name="cgonline">[http://web.archive.org/web/20020210002837/http://www.cgonline.com/previews/csconditio-01-p1.html CG Online - Counter-Strike: Condition Zero Preview]. Archived from the original on 2002-02-10.</ref> This was because each mission would only last around four or five minutes, about as long as a traditional ''[[Counter-Strike]]'' multiplayer game.<ref name="cgonline" />

When playing the single-player missions, friendly fire would be disabled.<ref>[http://www.pcgames.de/Counter-Strike-Condition-Zero-Spiel-20442/News/Counter-Strike-Condition-Zero-die-wichtigsten-Infos-34010/ PC Games - Counter-Strike: Condition Zero - die wichtigsten Infos]</ref> Since the game was played from the perspective of being the squad leader, death of the player would lead to a mission failure.<ref name="tiscalicz_randyint" /> In early previews, it was stated that dead teammates would be automatically resurrected after a mission to save players from the frustration of having to load a saved game.<ref name="intelgamer">[https://web.archive.org/web/20020127095920/http://www.intelgamer.com/news/articles/2163.htm Intelgamer.com - Counter-Strike: Condition Zero Interview]. Archived from the original on 2002-01-27.</ref> However, later previews indicate that the death of squad mates would've been permanent, making it necessary to replace them.<ref name="gamestar_0204" />

While no specific information regarding the fate of this mode was announced, it is assumed this single-player design was partially or completely replaced with the type of single-player mode presented at E3 in May 2002.

===Single-player, second iteration===
{{quote|Our focus with Condition Zero is on creating a cinematic, story-driven experience, much like [[Half-Life]].|Randy Pitchford<ref name="gamesdomain_2002" />}}
During the E3 show in 2002, a completely new type of single-player experience was unveiled which was a lot more reminiscent of the type in ''[[Counter-Strike: Condition Zero Deleted Scenes]]'' designed by [[Ritual Entertainment]].<ref name="avault_update" /><ref name="csczvault_joshint" /> This new type of single-player experience was mostly inspired by previous [[Gearbox Software]] titles such as ''[[wikipedia:Half-Life: Opposing Force|Half-Life: Opposing Force]]''.<ref name="actionvault_int" /> The decision to make such a major change in the single-player design at this point in development is believed to have originated from [[Valve Corporation|Valve Software]],<ref name="shacknews_ritual">[https://web.archive.org/web/20030127055853/http://www.shacknews.com/extras/e_czero_ritual/ Shacknews Article - Counter-Strike: Condition Zero (Ritual Entertainment)]. Archived from the original on 2003-01-27.</ref> and was made because the narrative of the original mode wasn't good enough.<ref name="pczone_0208" /> It is not completely clear to which extent this iteration of the single-player mode replaced the previous iteration.

[[File:Cscz gbx trailer junglecamp.png|thumb|Scripted sequence providing the narrative for [[Junglecamp]]]]In this updated design for the single-player game, the player was given the backstory of being a special forces soldier that is sent to various counter-terrorist units to impede terrorism.<ref name="actionvault_int" /> This mode would provide storytelling in the forms of cutscenes and scripted sequences and was a more linear type of game.<ref name="actionvault_int" /><ref name="csczvault_joshint" /> The narrative portion of the game included more scripted sequences than any previous games by [[Gearbox Software]].<ref name="actionvault_int" /> All of the scenes shown in the E3 demonstration (which was later released as the official trailer<ref name="csn_trailer" />) were scenes that would actually occur when playing the game.<ref name="pczone_0208">PC Zone - Issue 118 (2002-08) Dennis Publishing Ltd. - Read via [https://web.archive.org/web/20020926233440/http://www.coolguyskrew.co.uk/ Cool Guys Krew A Great Site for Cs stuff].

The missions for this mode were created by editing the maps that had been previously created for the old arcade-like single-player experience.<ref name="csczvault_joshint" /> For example, [[Dahab]] was modified to have a cutscene where a helicopter was shot down, providing the narrative for the task to extract the captured pilots.<ref>[https://web.archive.org/web/20020810224744/http://www.gamespy.com/e32002/pc/cscz/index.shtml GameSpy.com - E3 2002 Coverage - Counter-Strike: Condition Zero]. Archived from the original on 2002-08-10.</ref> Pitchford stated that there would be six chapters in the game with three or four missions each,<ref name="actionvault_int" /> suggesting that most of the already existing maps were to be converted to this new format.

===Skirmish===
A skirmish mode, which was a traditional multiplayer game against bots, was also available.<ref name="ign_preview" />

===Cooperative play===
The game was to feature cooperative play support where the narrative portion of the could be completed together with friends.<ref name="ferrago_int">[https://web.archive.org/web/20021105132751/http://www.ferrago.co.uk/story/65 Ferrago.co.uk | PC Games: Interviews | Counterstrike: Condition Zero - Randy Pitchford]. Archived from the original on 2002-11-05.</ref> All the single-player missions could be played cooperatively.<ref name="csn_randyint" /> While the single-player missions were designed for four player squads, Pitchford mentioned that there were no technical hindrances for cooperative games supporting as many players as traditional multiplayer games.<ref name="csn_randyint" />

===Multiplayer===
{{quote|In multiplayer, Condition Zero IS Counter-Strike.|Randy Pitchford<ref name="actionvault_int" />}}
In Gearbox Software's design of ''[[Counter-Strike: Condition Zero]]'' the multiplayer component was to be compatible with the original ''[[Counter-Strike]]'' in order to not separate the community.<ref name="ferrago_int" /> A patch was to be released for the original ''Counter-Strike'' to add cross compatibility.<ref name="cscentral" />

Much of the new content would therefore be released for the original ''Counter-Strike'' free of charge. This included all of the new maps and some of the new weapons.<ref name="gamespot_gdc" /> The weapons were to be released gradually, at a rate of about 2 weapons per update, to ensure that the weapons would be properly balanced.<ref name="gamehelper_e3" /><ref name="gamespot_e3">[http://www.gamespot.com/articles/e3-2002counter-strike-condition-zero-impressions/1100-2867658/ GameSpot - E3 2002: Counter-Strike: Condition Zero impressions]</ref> Some of the weapons, including the LAW, would likely not have been released to multiplayer.<ref name="csn_weapons" />

However, the bots and the higher quality player models would stay exclusive to owners of ''Condition Zero''.<ref name="gamespot_gdc" /><ref name="gameplanet" /> Owners of ''Condition Zero'' were to be able to freely customize their player model head and skin from the available choices when choosing their faction.<ref>[https://web.archive.org/web/20020827112442/http://www.xgr.com/article.php?article=2169 XGR.COM - The Net's FIRST 24/7 Radio Station For Gamers : The Randy Pitchford Interview]. Archived from the original on 2002-08-27.</ref>

Gearbox Software had close ties with the competitive scene, particularly with the [[wikipedia:Cyberathlete Professional League|Cyberathlete Professional League]] (CPL). Randy Pitchford was on the board of CPL and [[Mike Wardwell]] was the commissioner of the CPL, giving Gearbox a clear understanding of what was needed to accommodate professional competition.<ref name="halflife_nu" /><ref name="avault_czfeat" /> Perhaps due to this, the CPL announced plans to have ''Condition Zero'' featured at their summer 2002 championships.<ref>[https://web.archive.org/web/20020606124433/http://www.thecpl.com/press/sc1.htm Press Release - CPL Announces Summer Championship Event]. Archived from the original on 2002-06-06.</ref> However, due to the game being delayed, ''Condition Zero'' would not end up being featured at the event and the original ''[[Counter-Strike]]'' took its place.<ref>[https://web.archive.org/web/20020604065859/http://www.thecpl.com/index.html?p=sc2002 The Cyberathlete Professional League Summer Championship 2002 Event].

==Scenarios==
All the popular scenarios ([[hostage rescue]], [[bomb defusal]] and [[assassination]]) from the original ''[[Counter-Strike]]'' were going to return in the version of ''Counter-Strike: Condition Zero'' designed by [[Gearbox Software]].<ref name="gamespy_0109" /> New maps were designed for each of these scenarios,<ref name="pcgames_magazine" /> though [[Hangar|the only assassination map]] designed for this iteration of the game ended up getting cut when Gearbox Software was still developing the game.<ref name="csczvault_joshint" />

[[File:Cscz gbx hostages.png|thumb|New [[hostage]] variants]]
While the concept of these scenarios stayed the same, they were slightly updated. For the hostage rescue scenario, new hostage models were created that improved the polygon count to around 1000 polygons. Left-over models suggest that there were at least four different theme dependent skins (arctic, desert, European and jungle) with four different heads each.<ref>Counter-Strike: Condition Zero Deleted Scenes - Presence of ''props/deadguy_arctic.mdl'', ''props/deadguy_desert.mdl'', ''props/deadguy_euro.mdl'' and ''props/deadguy_jungle.mdl''</ref> The head variations suggest that in a regular hostage rescue scenario with four hostages, each hostage would have had a slightly different look. It is likely that a new [[VIP]] model was created for the [[assassination]] scenario to complement the new player and hostage models, but such a model was never shown to the public.

The introduction of one or two new multiplayer scenario types was also mentioned.<ref name="csn_randyint" /> One potential candidate for these new scenario types was a scenario where a player had to reach a certain area and perform an action (such as demolishing a computer). This would have differed from the bomb defusal scenario at least in the regard that no special equipment was needed allowing any player to function as the key player.<ref name="pczone_0112" /> Another candidate was a scenario where a team started off without weapons and had to escape from an area.<ref name="pczone_0112" /> It is not known how exactly this would have differed from the abandoned [[escape]] scenario. As all known new maps were created for one of the three "classic" scenarios, it is possible that these new scenarios would've functioned as an alternate or secondary scenario for select maps.

==Maps==
[[File:Cscz gearbox designer dallas team.jpg|thumb|Community mapping team at Gearbox Software]]
Several prominent community mappers, many known for their previous work on ''[[Counter-Strike]]'', were recruited by [[Gearbox Software]] to help out in map design during the development of ''[[Counter-Strike: Condition Zero]]''.<ref name="gamespy_0109" /> These people were [[David Johnston]], [[Christopher Auty]], [[Erik Doescher]], [[Alexander Manilov]], [[Matt Coombe]], [[Nick Coombe]], [[Dan Haigh]], [[Marc Schröder]] and [[Alex Gingell]].<ref name="gamespy_0109" /> [[Mike Wardwell]] was the lead level designer on the title.<ref name="avault_czfeat" />

Additionally, artists Mike Neumann, Ted Anderson and Chris Greenhaw were recruited to help provide textures for the maps.<ref name="csn_multi"> [https://web.archive.org/web/20020605061813/http://csnation.counter-strike.net/view.php/czinfo/multi.csn CS-Nation - condition zero multiplayer]. Archived from the original on 2002-06-05.</ref> To ensure an authentic look, Gearbox Software sent teams to five of the six campaign locations to take several gigabytes of photos to be used as texture source (texture sources for the Middle East were sourced from [[wikipedia:CNN|CNN]]).<ref name="ign_preview" />

The community mappers were originally recruited on a contractual basis for the design of a few maps.<ref name="thewall_schroeder">[http://www.thewall.de/forum/thread/biografie-gute-brushes-schlechte-brushes.../48998.1.html thewall.de Editing Forum - <nowiki>[</nowiki>Biografie<nowiki>]</nowiki> Gute Brushes, schlechte Brushes...]</ref> This allowed them to perform their work off site, making only a few visits to the offices of Gearbox Software during development.<ref name="csn_chrisint" /> Many of the community mappers would finish their contribution toward the project by the end of 2001.<ref name="linkedin_manilov" /><ref name="linkedin_ncoombe">[https://www.linkedin.com/in/nickcoombe LinkedIn | Nick Coombe]</ref><ref>[https://web.archive.org/web/20030413083004/http://halflife.multiplayer.it/articoli.php3?id=6597&page=5 Half Life Italia - Level design: eight experts confrontation - Nick “Crinity” Coombe].

Originally, there were plans to have over 16 maps divided into four campaigns based on themes (arctic, urban, desert and jungle).<ref name="gamespy_0109" /><ref name="homelan_randy" /><ref name="gamehelper_interview" /> By late October 2001, the amount of maps had been raised to 21 split into five campaigns (the urban campaign had been split into two: a Europe and North America campaign).<ref name="pczone_0112" /><ref name="avault_czfeat" /> Finally in December, the number of maps was raised to 25, which were divided into six campaigns of four maps (plus the training map).<ref name="gamespy_0112" /> The new sixth campaign was the Asian campaign.<ref name="gamespy_0112" /> The final rooster of campaigns was thus the jungles of South America, arctic Russia, urban Europe, Far East Asia, the United States and the Middle East.<ref name="gamespy_0112">[https://web.archive.org/web/20020201193603/http://www.gamespy.com/previews/december01/cscz/ GameSpy.com - Preview: Counter-Strike: Condition Zero Revisited].

All maps (except the [[Range|training map]]<ref name="lonegamers" />) would be playable in single-player, cooperative play and multiplayer.<ref name="csn_randyint" /><ref name="actionvault_intelligence">[https://web.archive.org/web/20020802115614/http://actionvault.ign.com/features/intelligence/cscz.shtml Action Vault - Counter-Strike: Condition Zero  Intelligence Report].

==Weapons and equipment==
The design featured 12 new pieces of equipment of which 8 were new weapons. New weapons were decided for the game based on their appropriateness for characters and locations or because they created new solutions for tactical problems in the game.<ref name="actionvault_int" /> However, some of the weapons were included simply because Gearbox felt they were "just plain cool".<ref name="actionvault_int" />

Notably, the high-definition content included in the design of ''Counter-Strike: Condition Zero'' by Gearbox Software would not include upgraded weapon models and the original models from ''[[Counter-Strike]]'' would still be used.<ref name="csn_randyint" />

==Factions and player models==
[[Gearbox Software]]'s iteration of the game kept the Russian [[Spetsnaz]] [[Counter-Terrorists|Counter-Terrorist]] faction which originated from [[Counter-Strike: Condition Zero (Rogue Entertainment design)|Rogue Entertainment's design]] and additionally introduced a new American [[Midwest Militia|Militia Extremist]] [[Terrorists|Terrorist]] faction.<ref name="ign_interview">[https://web.archive.org/web/20011201163232/http://pc.ign.com/news/37789.html pc.ign.com: Counter-Strike: Condition Zero Interview]. Archived from the original on 2001-12-01.</ref>

In addition to the new factions, each faction model could have four different heads.<ref name="gamespy_0109" /> Further variation was also achieved by introducing alternate skins for the character classes. [[Counter-Terrorists]] would wear mission appropriate camouflage in the form of arctic, jungle, desert and urban uniforms.<ref name="avault_czfeat" /> The urban camouflage was based on the real-world design for each unit.<ref name="pczone_0112" /> The [[Terrorists]] wouldn't don camouflage, but would wear environment appropriate clothing and you wouldn't "have guys running around in short sleeve shirts in the Arctic".<ref name="gamespy_0112" />

With 10 different factions having 4 unique head models and 4 unique skins/uniforms, a total of 160 different model combinations were possible.<ref name="csuk" /> Due to this huge amount of variation Gearbox quickly found themselves short of people to model. To overcome this issue, they started pulling in random visitors who they then photographed and motion captured to use as bases for their models.<ref name="gamesdomain_2002">[https://web.archive.org/web/20021222153956/http://www.gamesdomain.com/gdreview/zones/previews/may02/cs_condition.html Games Domain - Counter-Strike: Condition Zero hands-on - Pipeline Preview]. Archived from the original on 2002-12-22.</ref><ref name="ign_preview" /> This included people from package delivery companies such as [[wikipedia:United Parcel Service|UPS]] and [[wikipedia:FedEx|FedEx]].<ref name="actionvault_int" />

The new player models also offered an improvement in visual quality in addition to visual variation. In the original ''[[Counter-Strike]]'', player models had around 750 polygons each while the new models created by Gearbox sported around 1250 polygons.<ref name="gamespy_0109" /> There was also going to be lip-syncing for the models when players used radio commands.<ref name="gamespy_0109" /> All the player models were the work of Matt VanDolen.<ref name="avault_czfeat" />

==Music and sound effects==
Each campaign in the game would have an unique music score composed by Chris Jensen, who had previously scored the music for e.g. ''[[wikipedia:Half-Life: Opposing Force|Half-Life: Opposing Force]]''.<ref name="gameplanet" /> All sound effects were also to be enhanced to 16 bit sound quality.<ref name="intelgamer" />

==Interface==
The game main menu front end had been completely rethought and would be drawn by the game engine itself.<ref name="ign_preview" /> This meant that the menu would no longer be fixed at 640x480 and it would be possible to use any resolution in the main menu.<ref name="csn_tech">[https://web.archive.org/web/20021008073430/http://csnation.counter-strike.net/view.php/czinfo/tech.csn CS-Nation - condition zero technology]. Archived from the original on 2002-10-08.</ref>

[[File:Cscz csc cscz029.jpg|thumb|right|Interface with location and accuracy indicators]]
All the in game menus (e.g. the buy menu) as well as the mission load out and mission selection screens were designed utilizing the new VGUI 2.0 technology developed by Valve.<ref name="gamehelper_e3">[https://web.archive.org/web/20020816101513/http://www.gamehelper.com/common/default.asp?App_Module=ARTICLES&ID=210 Gamehelper.com - E3 | Condition Zero Update]. Archived from the original on 2002-08-16.</ref> The introduction of several new weapons also saw some changes to the buy menu interface. A separate menu for grenades was added, and the ability to repurchase the same weapons one bought in the previous round was also added.<ref name="gamespy_0109" />

The game interface also saw the addition of a text map location indicator in the lower-left corner of the screen. This was partly introduced due to the expanded size of the maps present in ''Condition Zero''.<ref name="csn_single"> [https://web.archive.org/web/20020605063936/http://csnation.counter-strike.net/view.php/czinfo/single.csn CS-Nation - condition zero single-player]. Archived from the original on 2002-06-05.</ref> Additionally, an accuracy indicator was also seen on the interface in some screenshots. This was probably added to make it easier to complete the challenge mode tasks which required the player to achieve a certain level of accuracy.

==Technology==
While still utilizing the original ''[[Half-Life]]'' engine, various enhancements were made to the technology in order to ensure a more current look for the game.

===Bots===
The bot technology was perhaps the single most important piece that the game centered on. [[Gearbox Software]] recruited Markus Klinge, the creator of PODBot, after testing all unofficial bots in an effort to find the best one.<ref name="gamespy_0109" /> Klinge now got access to the engine internals and could work together with the game engineers to improve the way the bots functioned.<ref>[https://web.archive.org/web/20070328115650/http://www.computerandvideogames.com/article.php?id=25843 ComputerAndVideoGames.com - Feature: Shifting up a gear: Randy Pitchford Interview]. Archived from the original on 2007-03-28.</ref><ref name="gamespot_video">[https://www.youtube.com/watch?v=e2RWs6vsPwE GameSpot - Counter-Strike: Condition Zero Video Interview. (2002). <nowiki>[video]</nowiki>. CNET Networks, Inc.]</ref>

The bots still relied on waypoints to guide them around, much like the original PODBot.<ref name="csn_randyint" /> Also, waypoints had to be manually created for each map,<ref name="tiscalicz_randyint" /> unlike the final bot by [[Turtle Rock Studios]] which has the ability to automatically learn new maps. However, the bot had the ability to learn from successes and failures and would revisit or avoid certain areas depending on previous outcomes.<ref name="gamespot_video" /> This functioned by having the bot update the waypoint file itself depending on the outcome.<ref name="gamehelper_gdc">[https://web.archive.org/web/20020622212317/http://www.gamehelper.com/common/default.asp?ID=162&App_Module=ARTICLES Gamehelper.com - GDC | At Ground Zero with Condition Zero]. Archived from the original on 2002-06-22.</ref> It was possible to turn this learning feature off.<ref>[https://web.archive.org/web/20020410004138/http://www.gamigo.de/index.php?site=previews_full&id_preview=703 gamigo.de - CS: Condition Zero - Angespielt]. Archived from the original on 2002-04-10.</ref>

There were also several possibilities for modifying the behavior of bots. One could manually edit the map specific waypoints to tweak the way in which the AI/bot would play the map.<ref name="csn_randyint" /> In addition, the bots had numerical values for several skill levels which could be modified from a simple text file.<ref name="gamehelper_gdc" /> Technically, these values ranged from 0-10 with floats giving actual possible skill levels from 0 to 99.<ref name="ign_preview" /> However, bots with skill levels over 5 (or 50) would be "doing head shots through doors", making it necessary to clamp the skill levels to 5 for the single-player mode.<ref name="ign_preview" /> There were 10 different skills in total, five of which were revealed:<ref name="gamehelper_gdc" /><ref name="pczone_0204" />
*Small Arms
*Rifle - Affected reloading speed and accuracy of rifles<ref name="avault_czfeat" />
*Demolitions - Ability to defuse bombs and utilize explosives (grenades)<ref name="avault_czfeat" />
*Awareness - Ability to react to surroundings, such as responding to the sound of gun fire<ref name="pczone_0204" />
*Tactics - Ability to communicate with other squad members and move as a unit<ref name="pczone_0204" />

Controlling the bots was to be kept simple since the people at [[Gearbox Software]] felt that complicated control systems were just a substitute for bad AI.<ref name="pcg_0205video" /> Originally, a player could control bots in their squad by using radio commands.<ref name="csuk">[https://web.archive.org/web/20011124025125/http://www.counter-strike.uk.net/features/cscz.php counter-strike<nowiki>[uk]</nowiki> - Counter-Strike: Condition Zero Preview]. Archived from the original on 2001-11-24.</ref> This was a somewhat extended version of the traditional radio command system to allow for better squad control.<ref name="pczone_0112" /> However, a later iteration aimed to remove the need for radio commands by making the bots react better to their surroundings and actions by the player.<ref name="gamehelper_gdc" /> This included things like responding to fire and mimicking the approach the player was making to areas.<ref name="gamehelper_gdc" />

For naming the bots, the nicknames of various people who were involved in the development of the title were used.

The bots had managed to fool a freelance gaming journalist into thinking he was playing against actual humans, a testament to the quality of the bot.<ref name="ign_preview" />

===Visual effects===
Improvements in how models were handled in the engine included the addition of support for alpha blended textures.<ref name="gamesdomain_2001">[https://web.archive.org/web/20011204190635/http://www.gamesdomain.com/gdreview/zones/previews/oct01/zero.html Games Domain - Counter-Strike: Condition Zero - Pipeline Preview]. Archived from the original on 2001-12-04.</ref>

A level of detail system was also added in ''[[Counter-Strike: Condition Zero]]''. There were about five different levels of detail for regular models and three levels of detail for special effects.<ref name="ign_preview" /> The detail level of models would change dynamically depending on the performance of the machine, thus ensuring compatibility with older machines.<ref name="ign_preview" />

Another new addition was a material system. It made material specific gibs possible meaning that shooting a wooden board would result in wood gibs and sound effects.<ref name="gamespy_0109" /> In order to utilize the system to its full potential, several different types of the same material were modeled into the game, including three different types of glass.<ref name="firingsquad_gdc" />

Finally, a weather system was also added into the game making it possible to have levels with rain or snow.<ref name="pczone_0112">PC Zone - Issue 109 (2001-12) Dennis Publishing Ltd.</ref> This was a purely visual feature that had no effect on gameplay.<ref name="pczone_0112" />

===Mapping, modding and editing tools===
New features for mapping included the possibility of placing world models into the void area, creating an illusion of a bigger playable area.<ref name="gearboxforum_entities">[https://web.archive.org/web/20020821145858/http://www.gearboxsoftware.com/forums/showflat.php?Cat=&Board=cscz&Number=45&page=&view=&sb=&o=&fpart=2&vc=1 Gearbox Software Forums - Designing Levels For CZ]. Archived from the original on 2002-08-21.</ref> This could also be used to make the sky seem like more than just a background image.<ref name="cscentral" /> Another new mapping entity was a particle emitter that could be used to make effects like smoke coming out of chimneys.<ref name="gearboxforum_entities" /><ref name="csn_tech" /> The location indicator that had been added to the interface was implemented by introducing location entities that were present in the map file.<ref name="gearboxforum_entities" />

Custom weapon models would not have been allowed in the game. This decision was made in an effort to thwart cheating where people would replace the models with "spiked models" making it considerably easier to detect other players.<ref name="cscentral" /> Curiously, custom player models would still be allowed.<ref name="cscentral" />

A new SDK was planned to be released coinciding with the release of ''[[Counter-Strike: Condition Zero]]''.<ref name="cscentral" /> This was going to enable the community to create custom single-player content for the game.<ref name="cvg_sdk">[https://web.archive.org/web/20071018051727/http://computerandvideogames.com/article.php?id=48859 ComputerAndVideoGames.com - PC Interview: Interview: Still-life? Not on your nelly]. Archived from the original on 2007-10-18.</ref> The SDK would include an updated version of Worldcraft (or possibly Gearcraft,<ref name="avault_czfeat" /> the Gearbox custom version of Worldcraft) and various other tools that Gearbox Software had developed during the design of Condition Zero.<ref name="tiscalicz_randyint">[https://web.archive.org/web/20020522134625/http://games.tiscali.cz/interviews/conditionzero/indexeng.asp Tiscali Games | Counter-Strike: Condition Zero - interview]. Archived from the original on 2002-05-22.</ref><ref name="cscentral" /> These other tools included updated versions of the map compiling tools by Zoner, which provided better quality lightning and texturing.<ref name="gamespy_0109" /> In addition, the new and improved player models would be included with the SDK to facilitate using them as base for other mods.<ref name="cvg_sdk" />

===Content delivery and anti-cheat===
The game was to be released both at retail and through the [[Steam]] client by [[Valve Corporation|Valve Software]].<ref name="avault_update" /> Besides allowing quick content updates, a major reason for its usage was the anti-cheat technology provided by it.<ref name="gamespot_gdc">[https://web.archive.org/web/20030622073715/http://www.gamespot.com/pc/action/counterstrikeconditionzero/preview_2857775.html Counter-Strike: Condition Zero Preview - Counter-Strike: Condition Zero Previews for PC at GameSpot]. Archived from the original on 2003-06-22.</ref> The original functioning principle of the anti-cheating technology was the verification of game files prior to launch and the ability to push quick updates in an effort to keep ahead of cheaters.<ref name="gamehelper_e3" />



==Legacy==
Despite essentially getting canned when [[Ritual Entertainment]] took over development on the title, many of the ideas would end up being used in future development of ''[[Counter-Strike]]'', ''[[Counter-Strike: Condition Zero]]'' and ''[[Counter-Strike (Xbox)]]'':
*The concept for the first iteration of the single-player design by Gearbox was used as the base for the [[Tour of Duty]] single-player mode by [[Turtle Rock Studios]], while the second iteration was used as the base for ''[[Counter-Strike: Condition Zero Deleted Scenes|Deleted Scenes]]'' by [[Ritual Entertainment]].
*Some of the multiplayer maps made their way into the final release of ''[[Counter-Strike: Condition Zero]]''. Other maps were used as starting geometry for the single-player missions produced by [[Ritual Entertainment]].
*The [[Tactical Shield]], [[IDF Defender|Galil]] and [[FAMAS]] made their way into regular ''[[Counter-Strike]]'' and ''[[Counter-Strike: Condition Zero]]''. In addition, the [[Machete]], [[M72 LAW]], [[Suicide Belt]] and the [[M60]] made their way into Ritual's single-player experience.
*Both [[Spetsnaz]] and [[Midwest Militia]] were included in the final version of ''Condition Zero''.
*A location indicator was inherited to the design of the game by [[Ritual Entertainment]], though it functioned in a quite different way.
*While the bots by Klinge were scrapped, the idea lived on in both Ritual's and Turtle Rock's designs.
*The weather system was eventually implemented into regular ''[[Counter-Strike]]'' and ''[[Counter-Strike: Condition Zero]]''.
*Support for alpha blended textures was also eventually implemented into regular ''[[Counter-Strike]]'' and ''[[Counter-Strike: Condition Zero]]''.
*The material system was inherited into Ritual's version of ''Condition Zero''.
*The Bot control idea eventually made it into [[Counter-Strike: Global Offensive]].
