Back in the old days of 2008, when Valve actually made and released new games on a semi-regular schedule, the publisher took a chance on independent developer Turtle Rock and a little co-op focused, AI-driven zombie swarm game called Left 4 Dead. The game was a multimillion-selling success, as was its 2009 sequel and associated DLC packs. So of course Valve and Turtle Rock built on that success by... letting the franchise lay fallow for almost a decade now.
Fast-forward to today, when Warner Bros. Interactive announced it has recruited Turtle Rock to bring the Left 4 Dead flavor back with the not-at-all-coincidentally titled Back 4 Blood.
While an accompanying FAQ makes it clear that this is not Left 4 Dead 3 (an IP that's owned by Valve, in any case), the announcement notes that the new game will share the same creators, development team, and zombie-shooting flavor of those well-remembered classics. "We get to return to a genre that was born in our studio with over ten years of additional experience and zombie ideas racked up in our brains," Turtle Rock cofounder and Design Director Chris Ashton said in a statement.
