Turtle Rock Studios, known for their commercially unsuccessful IP Evolve, have confirmed via their career page that they are in fact working on a new IP. Turtle Rock are currently looking for a Narrative Director, an Animation Programmer, a Senior Rendering Programmer, a Senior Character Artist and a Technical Artist for their unannounced new IP.
These job listings suggest the developers probably aren’t hard at working on Evolve 2, despite being received well by critics (), Evolve ended up selling poorly after the game’s initial launch month.
Prior to releasing Evolve, Turtle Rock were known for their work on several Valve games, including the creation of the Left 4 Dead series. Unfortunately, fans of the Left 4 Dead series probably won’t be seeing L4D 3 any time soon, at least not from Turtle Rock.
Phil Robb, the co-founder of Turtle Rock had this to say about the company’s partnership with Valve: “For us this is a big deal, this is our proving ground. We are not just Valve's bitch. I feel for the past 20 years we've been having to prove ourselves over and over. So here we are again, trying to prove ourselves.”
A lot of people credit Evolve’s season pass/DLC as being one of the key reasons the game seemed to fall off the face of the earth. It’s easy to see why this may have been the case, as DLC exclusive map-packs and characters are known to splinter a game’s player-base. This effect is even more powerful when the game is question already has a small player-base.
