Half-Life house Valve has acquired Turtle Rock Studios, the developer behind the upcoming co-op zombie shooter Left 4 Dead.
Orange County-based Turtle Rock has been closely involved with Valve, creating products based on Valve’s Counter-Strike team-based shooter franchise.
Turtle Rock’s Left 4 Dead is slated for release later this year.
Valve president Gabe Newell said in a statement, “We have been seeing very strong growth with Steam and Source, our content distribution and development platforms, up over 150 percent 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.”
Newell has said in the past, “What Counter-Strike did for multiplayer action games, Left 4 Dead will do for co-op games.”
Michael Booth, founder and CEO of Turtle Rock added, “Valve has had great success bringing in projects and teams such as Team Fortress and Portal. As I spent time working and talking with the creators of those products over the past several years, it became clear that this was the right next step for myself, my colleagues at Turtle Rock, our customers, and our products.”
Aside from game development, Valve is the creator of the successful Steam digital distribution platform and also licenses the Source Engine to third party developers.
