Coinciding with the twelfth anniversary of Counter-Strike Beta 1's release in 1999, Valve has announced it is working on a new title in the franchise, titled Counter-Strike: Global Offensive, or CS: GO.
Expanding upon the original's wildly successful team-based action gameplay, CS: GO will be a downloadable title targeted for release in early 2012 on Steam for PC and Mac, on Xbox Live Arcade and on PlayStation Network. It is being developed by Valve in cooperation with Seattle-based Hidden Path Entertainment.
CS: GO will introduce new gameplay modes, matchmaking, leader boards, "and more". Classic maps such as "de_dust" will return.
