Counter-Strike: Global Offensive (CS:GO) is a first-person shooter video game which is a part of the Counter-Strike series. It was announced to the public on August 12, 2011, and is developed by Valve Corporation and their partner, Hidden Path Entertainment. The game was later released on August 21, 2012, for the PlayStation 3, Xbox 360, Microsoft Windows, macOS, and later Linux as a downloadable title.
Counter-Strike: Global Offensive makes a few adjustments to the original gameplay formula of the Counter-Strike series. Compared to Counter-Strike: Source, weapon damage models were rebalanced. There is improved bullet penetration through some walls, materials, and objects.
The game pits two teams, Terrorists and Counter-Terrorists, against each other in different objective-based game modes. The most common game modes involve the Terrorists planting a bomb while Counter-Terrorists attempt to stop them, or Counter-Terrorists attempting to rescue hostages that the Terrorists have captured. There are nine official game modes, all of which have distinct characteristics specific to that mode.
