This Steam news bulletin reports that Valve Corporation acquired Turtle Rock Studios today. Turtle Rock is currently working on a team-based, multiplayer zombie FPS called Left 4 Dead that’ll utilize Valve’s Source engine.
Turtle Rock is no stranger to Valve either; their shared works include the Xbox port of the original Counter-Strike, partial development on Counter-Strike: Condition Zero and various maps for Counter-Strike: Source. Since both companies are working together now, I hope Turtle Rock can work on new maps for Team Fortress 2.
Gabe Newell, president of Valve, said, "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."
Michael Booth, founder and CEO of Turtle Rock Studios, said, "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."
Left 4 Dead is set for release in a few months on PC and Xbox 360.
