It was initially released as a modification ('mod') for Half-Life that was designed by Minh 'Gooseman' Le and Jess 'Cliffe' Cliffe before the rights to the mod's intellectual property were acquired by Valve, the developers of Half-Life, who then turned Counter-Strike into a retail product. The series began on Windows in 1999 with the release of the first game, Counter-Strike.
Counter-Strike ( CS) is a series of multiplayer first-person shooter video games in which teams of terrorists battle to perpetrate an act of terror (bombing, hostage-taking, assassination) while counter-terrorists try to prevent it (bomb defusal, hostage rescue).
