Vertigo (de_vertigo) is a bomb defusal map featured in Counter-Strike and later added to Counter-Strike: Global Offensive with the October 1, 2012 update.


Vertigo is based on a skyscraper that was under construction and centered the conflict between the Counter-Terrorist and the Terrorist teams. The main objective for the Terrorists were to bomb the building while the CTs must prevent them from achieving their goal.

Near the Terrorist Spawn Zone, there is a ladder leading from the first playable floor to the second playable floor that appears to be inaccessible from the bottom. In Global Offensive, a teammate can boost you up by crouching below the ladder. Prior to Global Offensive, the ladder can still be accessed from the bottom without teammates by carefully jumping from nearby ladders laying on the floor.

Another (infamous) fact is a CT can jump from the top spawn zone to descend below and quickly kill Terrorists at the beginning of a round. This is often achieved with a Negev or P90. (This is no longer possible since the current version of the map does not have both spawn points below each other)

Official description

Terrorists are trying to bomb Rizzleton tower before it reaches completion.

Counter-Terrorists: Prevent the building from being destroyed.

Terrorists: Plant the bomb and blow up the building.

Other Notes: Don't fall off.

Development History

Counter-Strike 1.6

Vertigo reused the textures from Half-Life and the background consisted of other skyscrapers. The props mainly consisted of construction materials, such as concrete. Vertigo's skybox is reused from Assault.

Counter-Strike: Global Offensive

The map was greatly revamped from the textures to the overall structure of the map, thus greatly enhancing realism. The background featured more realistic buildings and city streets from below, indicating that the unnamed building where the map takes place in is probably located somewhere in New York City.

The roofs of the bombsites were mostly removed and new props were added throughout the map. The height of the walls were reduced, allowing some players to jump on top of some props to eliminate stationary or incoming players. Finally, the middle hallways and the pathways that connected between the bombsites and the stairwell and ramp were changed to a great extent.

Notably, the ramp has two ladders and there is a penetrable wooden wall that blocks visual contact between the ramp and the entrances to bombsite A.

If the C4 was dropped outside of the building or into the elevator shafts, map triggers will return the dropped C4 back to the playable area.

On the November 13, 2017 update, the map was removed from the game files, making it inaccessible in game. The reason for removal was stated to be due to the map being a lesser played map. On the CS GO Blog, developers hinted that deleted maps could be reworked and re-added.[1]

On the January 24, 2019 update, the map was reworked and re-added to the game (along with Zoo and Abbey), but only for play on Wingman.[2] Initially only Bombsite B was accessible (while the rest of the map was noted to also have been changed), then in the March 7, 2019 update, the gameplay area was changed to only include Bombsite A. The map was made fully available for the bomb defusal mode for both Casual and Competitive gameplay in the March 19, 2019 update.

On the March 28, 2019 update, the map was moved from Reserves Group into the Active Duty Group while Cache has been moved from Active Duty Group into Reserves Group while it undergoes some renovations.

The official factions for this map are the FBI and the Professionals.

  • Moved generator in T spawn up to second floor
  • Made it slightly easier to throw grenades out of ceiling in T corridor to mid
  • Minor tweaks and fixes


  • Bots can occasionally fall off, especially those who are being engaged by enemies while strafing. However, this only applies for higher difficulty bots as normal and easy bots will not strafe unless they see a sniper.
    • In CS 1.6 and Condition Zero, bots from both teams may jump off the building by accident though this is quite rare. The problem is presumably navigation issues.


  • Vertigo means "height sickness" or dizziness caused by looking down from a great height as the conflict is centered around an incomplete skyscraper.
  • If a player falls off the map, the console will read "{Victim} killed self (with headshot) from trigger_hurt"
  • A secret enclosed room can be found right beneath bombsite B, accessible via noclip or free look spectator mode. The room contains the developer credits.
  • Some of the "unprotected" edges are barricaded with invisible walls like the two walls at the CT spawn zone, but any weapons and the C4 entity will bypass the invisible barricade.
  • The corpses of players will simply "stop" after falling through 3-4 floors in Counter-Strike 1.6 due to a map border limit.
  • A player falling off the map can hear screaming and a splat sound before dying.
Global Offensive
  • Some of the .NAV file areas are named "50th floor" and "51st floor", indicating that the skyscraper has 51 stories.
  • On Wingman mode only, a helicopter can be seen hovering in the sky on the Northeastern corner of the map. Shooting at the helicopter will cause it to fly away. In this case, its broadcast will be interrupted, which is shown on the TV set on the Terrorist base.
    • This helicopter is similar to the one which survivors are saved in the "No Mercy" campaign from another Valve's game - Left 4 Dead. It is noteworthy that the campaign finale also takes place on the roof of a skyscraper.
  • Signs saying "This jobsite has suffered X injuries" were added to the map in the March 21, 2019 update. The sign counts the number of deaths from falling off the map, starting at 0 at the start of the map, and increases by the number of deaths from falling in the last round at the start of every new round.
