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. 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. Several spin-off titles have been released for Asian territories.
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.
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 11 August 2004. On 18 August 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 23 June 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 runs 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. The game involves anime-designed characters in a futuristic designed version of Counter-Strike. A selection of single-player missions, mini-games, and seasonal events were added to prolong the game's interest with players.
Counter-Strike Online series
Counter-Strike Online is a free-to-play spin-off available in South Korea, Japan, Taiwan, China/Hong Kong, Singapore, Malaysia, Indonesia and Turkey. It was developed by Nexon Corporation with oversight from Valve. It uses a micropayment model that is managed by a custom version of the Steam back-end. Announced in 2012 and aimed at the Asian gaming market, a sequel titled Counter-Strike Online 2 was developed by Nexon Corporation on the Source game engine.
Counter-Strike Nexon: Zombies
In August 2014, Nexon announced Counter-Strike Nexon: Zombies, a free-to-play, zombie-themed spin-off, developed on the GoldSrc game engine. On 23 September 2014, an open beta was released on Steam. The game launched on 7 October 2014, featuring 50 maps and 20 game modes. The game features both player versus player modes such as team deathmatch, hostage rescue, bomb defusal, and player versus environment modes such as cooperative campaign missions and base defending. Reception from critics was generally negative with criticism aimed at the game's poor user interface, microtransactions, and dated graphics.
