Condition Zero was first introduced as a modification (mod) for the original Counter-Strike, released in 2000. Developed by a community-driven team with the support of Valve Corporation, it aimed to provide a more authentic and competitive Counter-Strike experience. The mod's popularity led to its integration into Counter-Strike: Source and later into the mainline Counter-Strike: Global Offensive (CS:GO) as a game mode.
