Epic Games, makers of things Unreal and Gears of War, are fully on board with this Project Natal thing that Microsoft has cooked up. VP Mark Rein calls the company's popular Unreal tech "the unofficial engine of Natal."
In an interview with OXM UK, Rein says he also considers Unreal the "economic engine of Natal," the platform upon which developers should go to if they "want to get a big headstart and use the same tech as Microsoft." Sounds official enough to us.
Rein also says that, going forward, don't be surprised if you see Natal's motion and voice detection control schemes in future Epic Games titles.
"I have no idea what we're going to do from a game standpoint, but from an engine standpoint, it's definitely cool stuff, and we will support it," he says. "I think any future Xbox games we make will have some Natal support."
