'''''Counter-Strike''''' ('''''CS''''') is a series of [[multiplayer]] [[tactical shooter|tactical]] [[first-person shooter]] video games, in which opposing teams attempt to complete various objectives. The series began on [[Microsoft Windows|Windows]] in 1999 with the release of the first game, ''[[Counter-Strike (video game)|Counter-Strike]]''. It was initially released as a [[Game mod|modification]] ("mod") for ''[[Half-Life (video game)|Half-Life]]'' that was designed by [[Minh "Gooseman" Le]] and [[Jess "Cliffe" Cliffe]] before the rights to the mod's [[intellectual property]] were acquired by [[Valve Corporation|Valve]], the [[Video game developer|developers]] of ''Half-Life'', who then turned ''Counter-Strike'' into a retail product released in 2000.

The original ''Counter-Strike'' was followed by ''[[Counter-Strike: Condition Zero]]'', developed by [[Turtle Rock Studios]] and released in March 2004. A previous version of ''Condition Zero'' that was developed by [[Ritual Entertainment]] was released alongside it as ''Condition Zero: Deleted Scenes''. Eight months later, Valve released ''[[Counter-Strike: Source]]'', a remake of the original ''Counter-Strike'' and the first in the series to run on Valve's then-newly created [[Source (engine)|Source engine]].<ref name="Counter-Strike: Source beta begins">{{cite news |title=Counter-Strike: Source beta begins |url=http://www.gamespot.com/pc/action/counterstrikesource/news.html?sid=6104577 |work=[[GameSpot]] |publisher=[[CNET Networks]] |date=August 11, 2004 |access-date=July 1, 2008 |archive-url=https://web.archive.org/web/20140314043506/http://www.gamespot.com/articles/counter-strike-source-beta-begins/1100-6104577/ |archive-date=March 14, 2014 |url-status=live }}</ref> The fourth game in the main series, ''[[Counter-Strike: Global Offensive]]'', was released by Valve in 2012 for Windows, [[OS X]], [[Xbox 360]], and [[PlayStation 3]].
