Valve has announced the sequel to its classic online shooter Counter Strike, which will be playable for the first time in Europe at the Eurogamer Expo in September.
"Counter-Strike took the gaming industry by surprise when the unlikely MOD became the most played online PC action game in the world almost immediately after its release in August 1999," said Valve's Doug Lombardi.
"For the past 12 years, it has continued to be one of the most played games in the world, headline competitive gaming tournaments and selling over 25 million units worldwide across the franchise.
"CS: GO promises to expand on the CS' award-winning gameplay and deliver it to gamers on the PC as well as the next gen consoles and the Mac."
Development of the game has been lead by Hidden Patch Entertainment in Seattle, with close collaboration from Valve itself.
The game will feature updated assets from Counter Strike: Source, including maps and weapons, as well as completely new content.
Counter Strike: Global Offensive will be available on PSN, Xbox Live and PC and Mac via Steam in early 2012.
