Counter-Terrorists must rescue hostages captured and put into a warehouse by a group of Terrorists. Despite being included in Counter-Strike and Counter-Strike: Source, both versions are noteworthy for their extreme differences. Counter-Strike: Source brought forth a very realistic approach, as well as excluding the Security cameras. Besides taking away the cameras, one of the major changes was the replacement of the highway with the train station. Some players got frustrated with the new changes, however, they are still present in Counter-Strike: Global Offensive. Even so, Assault is still one of the most popular maps in all Counter-Strike games.
This map is considered to be unbalanced and gives an advantage to the Terrorist team as they can easily swarm around higher sections of the map, including the warehouse. In Source, this problem was somewhat nullified as the back entrance of the warehouse has an additional entry-point on the second floor. In Global Offensive, CTs can shoot Ts from the roof due to the windows, balancing the map more.
Counter-Terrorists: Rescue the hostages. Take out the terrorists without jeopardizing the hostages. The terrorists may be watching you with their cameras. Terrorists: Prevent counter-terrorist force from rescuing the hostages. Use whatever force needed. Other notes: There are 4 hostages in the mission. Rescue them!
The Marr Freight Company has fallen victim to a band of terrorists hell bent on using their operation to launder money. The Harper Appliance Company is unwittingly shipping out more than they bargained for. Counter-Terrorists: Enter the terrorist stronghold and rescue the hostages. Take out the terrorists without jeopardizing the hostages. Terrorists: Prevent counter-terrorist force from rescuing the hostages. Other notes: There are 4 hostages in this mission.
There are several important differences from the retail map in the Beta 1.1 version of Assault.
- The hostages do not have their own room. They are just standing in the camera room in the Terrorist Spawn Zone
- There are no containers past the back entrance.
- The second ladder on one of the containers near the front entrance is missing.
- The containers near the front entrance are in a different position compared to later versions.
- There is no additional vent that is leading to T Spawn Zone camera room. Also, the lightning in the vents is missing (it's a lot darker).
- The bridge nor the road under the bridge are inaccessible. These pathways were blocked off by a police blockade and a fence respectively.
- Dumpsters near the bridge are missing.
The map was largely updated bringing it close to the final version. This version of Assault features a Half-Life desert canyon skybox instead of the night city one seen before. This change was reverted in the next patch, Beta 2.1 .
The hostage room was expanded and a fourth hostage was added.
The map was visually overhauled and the time has been changed to day. A new second floor back entrance was added, right above the original back door. The security cameras have been removed.
This version is very similar to the version seen in Counter-Strike Source. One notable change is the addition of skylights on the roof of the warehouse allowing Counter-Terrorists to look inside the warehouse before entering and attack the Terrorists.
- Assault (
gd_assault) has a separate unused map for the Guardian mode.
- The objective was "Plant the bomb or get 10 AWP kills".
- Bots have common navigation problems in this map due to its narrow passages and ladders, such as the catwalks in the warehouse or the vent accesses. In early Counter-Strike games, bots may fall to their death sometimes. It's also common for bots to get stuck in the vents.
- In Counter-Strike and Condition Zero, the CT Spawn Zone does not show the Hostage rescue zone on the HUD. Instead, the Buy zone icon is used in place for the Rescue zone.
- In Counter-Strike, a buy zone for the Terrorist team is available at the roof above the main entrance of the warehouse. This mistake happens because the spawn zone for the Terrorists is just close enough to the roof.
- In Global Offensive, the ventilation shaft is quite bugged as it's possible for other players to see enemies inside. Example is the the blocked off vent hole is actually visible for player below who looks at the skylight (but not for the player who's in the vent). In addition players at train tracks may fully visible see the player at the end of the upper vent.
- In Counter-Strike 1.6, there's a grammatical error on the entrance sign of the warehouse; it reads 72th street rather than 72nd street.
- In Counter-Strike, a satellite dish above the CT spawn truck can be destroyed by firing at it repeatedly, inflicting minor damage for everyone caught in the blast radius. This renders the security camera permanently interoperable even round restart unless map is reloaded.
- The containers in Counter-Strike have the Black Mesa logo on them while in Counter-Strike: Source and Counter-Strike: Global Offensive, they have the "Starline" logo instead.
- In Counter-Strike: Source, if one becomes a spectator and goes through the ground near the CT spawn zone, or uses noclip, a room containing a single boot can be found.
- In Source, Assault appears to be located on Belmont Avenue in Chicago, as stated by a sign on the railroad. The coordinates on the sign match the station's location in real life.
- The same sign appears in Global Offensive; however, additional signs added into the map make Assault's location inconclusive. A road sign for Riverside can be seen under the train station, possibly referring to the fictional town of Riverside, Pennsylvania from Left 4 Dead. Another road sign down the street references Interstate 405, an auxiliary interstate highway running through the west Los Angeles area. Curiously, this sign lists Redmond, Clyde Hill, and Overlake as nearby locations; all three are located east of Seattle, Washington.
- In Global Offensive, there is a rack in the hostage room that contains all the weapons featured in the game, which is derived from the Weapons Course. These weapons are static and cannot be obtained; as the glass is unbreakable.
