Counter-Strike (aka CS) is a tactical first-person shooter video game which originated from a Half-Life modification by Minh "Gooseman" Le and Jess "Cliffe" Cliffe. The game has been expanded into a series since its original release, which currently includes Counter-Strike: Condition Zero, Counter-Strike: Source, Counter-Strike: Anthology and Counter-Strike on Xbox.
Counter-Strike pits a team of counter-terrorists against a team of terrorists in a series of rounds. Each round is won by either completing the mission objective or eliminating the opposing force. The latest incarnation of the game, Counter-Strike: Source, is based on the Source engine developed for Half-Life 2.
CS is almost entirely based on the dynamically streamlined multiplayer experience activated
Counter-Strike was developed first as a Half-Life modification. Therefore named "Half-Life: Counter-Strike." The original version was a 3rd-party Half-Life modification, but since then it has grown into a commercial mod and later advertised as separate game in itself. Counter-Strike still uses and runs on the Half-Life game engine and is based on its unchanged structure.
