With the announcement of Gears of War: Judgment, some were surprised to hear that Bulletstorm developer People Can Fly is pitching in on the game’s development. Epic Games design director Cliff Blezsinski and People Can Fly founder Adrian Chmielarz explained to Joystiq why the collaboration came about.

“It takes multiple studios now to really make a game that can have all of this between the campaign and multiplayer and the co-op elements and things like that, and plus they're quite fucking crazy, to be honest with you," said Blezsinski.

"Making the campaign have that many Locust and be that intense made it a requirement for the younger guys working on the Epic side to refine the controls, and there's just non-stop back and forth [between Epic and People Can Fly]."

People Can Fly is not well-versed in all things Gears of Wars, so together both developers can find something new to say about the universe.

"The big idea is, yes, we can bring something fresh to this. I think we basically inspire each other – we have these new ideas and then sort of shake the foundation of Gears up without changing too much; it's still Gears,” added Chmielarz.
