Nuke (de_nuke), is a Bomb Defusal map featured in Counter-Strike, Counter-Strike: Source, and Counter-Strike: Global Offensive.

The map takes place in a warehouse containing nuclear materials or a nuclear power plant. In Global Offensive, the original version of the map takes place in a German nuclear power plant, while the revamped version takes place in an American one.

Unlike most Counter-Strike bomb defusal maps, the map revolves around a central structure rather than multiple lanes, with the two bombsites being overlapped on top of each other.

The original Global Offensive version is largely a copy of the Source version, with some changes in the looks of the map and gameplay. In the Beta version, all the hallways in the basement has been removed, leaving only Ramp and Vents the entrances to the bombsite.

During the Beta, professional player and mapper Salvatore "Volcano" Garozzo created his own version of the Global Offensive Nuke, named de_nuke_ve, which made many changes to the map and was accepted by tournaments as "a competitive revision" of the map. On the December 12, 2012 Update, Valve incorporated changes from Volcano's version of Nuke into the Global Offensive Nuke.[1]

In the final version, the crates at Bombsite A and the nuclear missile in Bombsite B have been replaced with nuclear containment barrels. A somewhat significant change in the structure of the map is that the entrance to the lower area of the facility from the outside has been moved slightly away from the CT Spawn Zone and the basement has been removed. Instead of having two pathways, one of the lesser used pathways near bombsite B has been converted into a storage room.

Following the revamp of Train, Nuke was removed from the Active Duty map group and replaced by Train after the March 31, 2015 update. Nuke was later revamped and released alongside Operation Wildfire, incorporating a lot of the feedback to balance out the new version. Shortly after, Nuke was re-introduced to the active map pool, replacing Inferno.

Some of the revamped Nuke's major changes include removing one of the vents between bomb sites, re-opening the access from tunnels to Lower B, blocking access to part of Upper A and easier access to Silo.

The ventilation covers connecting Site A and B can now be interacted with to close and open them, shutting off sight lines. They can still be destroyed normally.

As of now, the official factions are the FBI for the Counter-Terrorist side and the Phoenix Connexion as the Terrorists.
