Counter-Strike began as a Half-Life mod created by Minh Le and Jess Cliffe in 1998-1999. The public beta launched on June 19, 1999 and ran through seven major beta cycles, culminating in the full retail release on November 8, 2000. When Valve launched Steam in 2003, Counter-Strike 1.6 became one of the first titles distributed digitally - and it remains one of the longest-running active games in Steam history. As of 2013, Valve ported the game to macOS and Linux, making it available across all major desktop platforms with no end of service announced. Latest API refresh: 2026-03-21 10:41 UTC.
