Counter-Strike is a mod for Half-Life about the confrontation between terrorists and operatives, which has been reborn into a separate game.

Although Counter-Strike is one of Valve's main games, its real creators are Minh Lee aka Gooseman and Jess Cliffe. Lee wanted to create something more realistic. Then he came up with the idea of ​​a confrontation between special forces and terrorists. When Half-Life came out, Gooseman decided that the new game was much better suited for his purposes than Quake, and he was right.

The mod became a real hit, and in 2000 it attracted the attention of Valve, who invited Min Li to work, thereby obtaining the rights to the mod. That same year, Counter-Strike was released as a full-fledged game.
