Valve has released Counter-Strike: Global Offensive, a long-awaited update to its multiplayer first-person shooter. The game is available through Steam, and marks just the second time that Valve itself has done a simultaneous Mac/Windows launch through the service. In the past couple of years Valve has turned more attention to Mac support for both first- and third-party releases, compensating for the fact that most Steam content is otherwise Windows-centric.
