Counter-Strike (frequently abbreviated as CS) is a series of multiplayer first-person shooter video games, in which teams of terrorists and counter-terrorists battle to, respectively, perpetrate an act of terror (bombing, hostage-taking) and prevent it (bomb defusal, hostage rescue). The series began on Windows in 1999 with the first version of Counter-Strike. It was initially released as a modification for Half-Life and developed by Minh "Gooseman" Le and Jess "Cliffe" Cliffe, before the rights to the game's intellectual property were acquired by Valve Corporation, the developers of Half-Life. The game was followed-up with Counter-Strike: Condition Zero, developed by Turtle Rock Studios and released in 2004. Later that same year, Counter-Strike: Source was released by Valve Corporation. Released only eight months after Counter-Strike: Condition Zero, in November 2004, the game was a remake of the original Counter-Strike and the first in the series to run on Valve's newly created Source engine.
An arcade adaption of the Counter-Strike series titled Counter-Strike Neo was released in 2005. In contrast to previous iterations in the series, the game was developed by Nexon Corporation and published by Namco. With various parallels to Counter-Strike Neo, Counter-Strike Online was released in 2008, developed again by Nexon Corporation with oversight from Valve Corporation.
The fourth game in the main series to have been developed by Valve, Counter-Strike: Global Offensive, was released in 2012 for Windows, OS X, Xbox 360, and PlayStation 3. Hidden Path Entertainment, who also worked on Counter-Strike: Source post-release, helped to develop the game alongside Valve.
Originally a modification for Half-Life, the rights to Counter-Strike, as well as the developers working on it, were acquired by Valve Corporation in 2000.
Counter-Strike: Condition Zero
Counter-Strike was followed-up with Counter-Strike: Condition Zero, developed by Turtle Rock Studios and released in 2004. It used the Half-Life GoldSrc engine, similar to its predecessor. The game was poorly received in contrast to its predecessor and was quickly followed with a further entry to the series titled Counter-Strike: Source.
A remake of the original Counter-Strike, Counter-Strike: Source was the first publicly released game by Valve Corporation to run on the Source engine. Counter-Strike: Source was initially released as a beta to members of the Valve Cyber Café Program on August 11, 2004. On August 18, 2004, the beta was released to owners of Counter-Strike: Condition Zero and those who had received a Half-Life 2 voucher bundled with some ATI Radeon video cards. While the original release only included a version for Microsoft Windows, the game eventually received a port to OS X on June 23, 2010 with a Linux port afterwards in 2013.
Counter-Strike: Global Offensive
Counter-Strike: Global Offensive was the fourth release in the main, Valve-developed Counter-Strike series in 2012. Much like Counter-Strike: Source and other Valve games released in recent years, the game ran on the Source engine.
A Japanese arcade adaptation of Counter-Strike, the original Half-Life multiplayer modification. It is published by Namco, and runs on a Linux system.
