Valve announces Counter-Strike: Global Offensive is now available for worldwide pre-purchase on Steam, offering the upcoming multiplayer shooter at a 10% discount. This will also entitle customers to early access to the game's beta on August 14th, which is a week before its planned official release. Word is:

CS: GO expands on the classic team-based action gameplay that Counter-Strike pioneered. Featuring an arsenal of over 45 weapons, loads of maps, new game modes, new visuals, leaderboards and over 165 Steam Achievements.

Additionally, players can take advantage of huge savings on the entire Counter-Strike franchise during this week's Midweek Madness from August 7 - August 9.
