カウンターストライク２/ Counter-Strike 2

Counter-Strike 2 is a free-to-play multiplayer tactical first-person shooter developed and published by Valve. Released in September 2023, it is the fifth main entry in the Counter-Strike series and serves as a direct replacement for Counter-Strike: Global Offensive on Steam. Two teams, Terrorists and Counter-Terrorists, compete in objective-based rounds across modes such as bomb defusal and hostage rescue. Built on the Source 2 engine, the game introduced volumetric smoke physics, revised weapon handling, and a new sub-tick server architecture. It inherited all cosmetic items from its predecessor and features both a map-specific Competitive mode and a numerically ranked Premier mode.
