Counter-Strike: Global Offensive is an online first-person shooter developed by Valve Corporation and Hidden Path Entertainment,who also maintained Counter-Strike: Source after its release.It is the fourth game in the Counter-Strike franchise,excluding Neo and Online.
Counter Strike Global Offensive was released on August 21, 2012, and made available for Microsoft Windows and OS X on Steam, Xbox Live Arcade, and a US-only version on PlayStation Network. 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 and PSN players,but was ultimately limited to Windows and Mac OS because of the differences in update-frequency between systems.The PSN version offers three input control methods, which include using either the DualShock 3 controller, PlayStation Move or USB keyboard/mouse.
