Counter-Strike: Global Offensive (CS:GO) is a multiplayer first-person shooter video game developed by Hidden Path Entertainment and Valve Corporation. It is the fourth game in the main Counter-Strike franchise.
Counter-Strike: Global Offensive was released for Microsoft Windows, OS X, Xbox 360, and PlayStation 3 on August 21, 2012. The Linux version was released in September 2014. It features classic content, such as revamped versions of classic maps, as well as brand new maps, characters and game modes. Cross-platform multiplayer was planned between Windows, OS X, Linux, and PlayStation 3 players, but was ultimately limited to Windows, OS X, and Linux because of the differences in update-frequency between systems.
