Counter-Strike 2 (CS2) is a multiplayer tactical first-person shooter game developed by Valve. Announced on March 22, 2023 and officially released on September 27, 2023, Counter-Strike 2 is the fifth generation of the Counter-Strike series and replaces CS: GO on Steam, which was released in 2012. Like its predecessor, the game pits two groups of players, Counter-Strike and Terrorist, against each other in various game modes, most of which revolve around completing specific goals. Counter-Strike 2 includes major technical improvements, including an updated game engine from Source to Source 2, the introduction of interactive "responsive smoke," improved graphics, and a redesign of some of the classic maps.
