Counter-Strike: Global Offensive (CS:GO) is a 2012 multiplayer first-person shooter developed by Valve and Hidden Path Entertainment. It is the fourth game in the Counter-Strike series. Developed for over two years, Global Offensive was released for Windows, macOS, Xbox 360, and PlayStation 3 in August 2012, and for Linux in 2014. Valve still regularly updates the game, both with smaller balancing patches and larger content additions.
