Nuke is the Counter-Strike map set around a nuclear research facility.
Nuke is a bomb-defusal map built around two vertically arranged bombsites. Its industrial setting includes a nuclear facility, reactor areas, storage spaces, and connecting stairways and corridors. The unusual vertical design makes movement between the upper and lower sites a defining part of the map.
The map first appeared in the original Counter-Strike and has been revised across later games, including Counter-Strike: Source, Global Offensive, and Counter-Strike 2. Although layouts and visual details have changed, the nuclear-industrial theme has remained recognizable.
Nuke is sometimes confused with Cache because both feature industrial environments. Cache is associated with a military-industrial depot, while Nuke’s identity comes from its reactor complex and split-level bombsite structure.
