Still, few captured the magic of that first Left 4 Dead. Valve put out a second Left 4 Dead developed in-house, and countless other studios replicated the formula to varying results. Left 4 Dead was a smash hit for the developer, and both paved the way for the co-op shooting genre and contributed to a zombie explosion in gaming.įollowing the studio’s split from Valve in 2009 (where Valve retained the Left 4 Dead IP), Turtle Rock began work on what would eventually become the asymmetric multiplayer shooter Evolve. Valve was so impressed by the project that it acquired Turtle Rock in 2008 and released the game later that year. However, the studio truly made its name through its first all-original game, a cooperative zombie shooter called Left 4 Dead.
Founded in 2002, Turtle Rock Studios got its start working on the Counter-Strike and Half-Life series alongside Valve.
