The next entry in the Counter-Strike series is coming early 2012 as Counter-Strike: Global Offensive. Global Offensive will be released through Steam (compatible with PC and Macs), Xbox LIVE Arcade, and the PlayStation Network.
CS: GO features new maps, modes, weapons, matchmaking, and leaderboards to compare scores with other players. In addition to the new content, CS: GO will also include updates of fan-favorite maps like de_dust.
CS: GO will be shown off at this year's PAX Prime and London Games Festival events where it will be playable by attendees.
