Terrible news for immobile couch potatoes: According to a Square Enix representative, Infinite Undiscovery will ship on two discs when it releases exclusively on the Xbox 360 in September. The real-time role-playing title from tri-Ace marks the first game to be published by Square Enix on an Xbox platform since 2006's space shooter, Project Sylpheed.

Shipping on September 2 in North America, September 5 in Europe and September 11 in Japan, Infinite Undiscovery promises an epic 20-25 hour adventure for the Xbox 360. And that's just while you're busy changing discs.
