Counter-Strike

Counter-Strike (originally marketed as Half-Life: Counter-Strike) is a multiplayer first-person shooter initially created by Minh Le and Jess Cliffe as a mod for Half-Life. By the fourth beta, Valve Corporation began assisting the two developers and ultimately offered them jobs. Both of them accepted, and the rights for the game were acquired by Valve. After over a year of public beta testing, the retail version of Counter-Strike was published by Sierra Entertainment on November 8, 2000 for Microsoft Windows. Since the creation of the franchise, various sequels and spinoffs have been created such as Counter-Strike: Condition Zero, Counter-Strike: Source and Counter-Strike: Global Offensive. Counter-Strike Nexon: Zombies uses the same engine, GoldSrc.
