There have also been several official third-party spinoff titles developed for Asian gaming markets over the years. As of 2020, Valve continues to support Global Offensive with regular updates and sponsored competitive tournaments. In 2012, Valve released Counter-Strike: Global Offensive, a completely modernized take on the series. In 2004, Valve released Counter-Strike: Condition Zero, a reworked version of the original game with two singleplayer campaigns, and Counter-Strike: Source, a port of the game to Valve's new Source engine. It was later made as a standalone game in 2003 on Valve's then-new Steam digital distribution platform, after which it was most commonly known as Counter-Strike 1.6.

Impressed with the mod, Valve hired Le and Cliffe and turned Counter-Strike into a retail product, which they released as Half-Life: Counter-Strike.

Counter-Strike began as a modification developed by Minh "Gooseman" Le and Jess "Cliffe" Cliffe for Valve's Half-Life.
