Turtle Rock have announced what they’re doing next, though they’re yet to give it a name. It will be a fast-paced, co-op focused FPS developed in association with the community. For a publishing partner they’ve got F2P moguls Perfect World, and while they’re yet to announce a business model, that hints strongly that you won’t be paying a full boxed price.
Given they’ve made one of the best co-op games ever, quite the pedigree to live up to.
As for setting, it’s a “new franchise” in an “all new universe” and all Steve Goldstein, president of Turtle Rock, would tell GI.biz about it is that it’s got a “strong dark fantasy element” to it. He also clarified that it isn’t post-apocalyptic or zombie-related, clearly distancing it from Left 4 Dead while maintaining that it will appeal to fans of the studio’s particular co-op style.
Co-founder Phill Robb says that it "leverages the style of gameplay our community loves and expects from Turtle Rock Studios. We're focusing on what we do best - heart-pounding moment-to-moment online co-op FPS action.” He goes on to say that the plan is constant communication with players, and makes it sound like some sort of soft-launch beta / early access period is on the cards.
They speak a lot about “service-orientated games” - League of Legends, Dota 2 and Overwatch to you or I - and how they’re proving far more popular than a traditional boxed product and increasing competition for those normal releases. Much more in the full interview.
