Valve announced that it has acquired Turtle Rock Studios, the Orange County-based development studio behind portions of Counter-Strike: Condition Zero, various Counter-Strike maps and the upcoming Left 4 Dead game.
The studio’s Left 4 Dead joins Valve’s game properties which includes the blockbuster Half-Life franchise, Counter-Strike, Team Fortress and Day of Defeat series of games, as well as Portal.
“We have been seeing very strong growth with Steam and Source, our content distribution and development platforms, up over 150% over the last 12 months. Given our expectations for Left 4 Dead and our long-standing relationships with members of the Turtle Rock team, this was an easy decision. It also gives us a base from which to expand our development activities in the Los Angeles area,” said Gabe Newell, president of Valve.
Left 4 Dead is now expected to be released this Summer on PC.
