In an interview with IGN, Bleszinski, lead designer at Epic, said, "We've added five new chapters to the single-player campaign. These chapters take place later in the campaign, right in the middle of Act Five." Producer Fergusson added, "In Gears of War for 360, the Brumak, aka '40 feet of guns, armor and teeth,' was a cinematic character, but in Gears of War for Windows, the Brumak is a relentless beast that chases you throughout the five new campaign chapter and ultimately climaxes in a boss fight where you can finally take the big guy down."
While Gears of War will support Games For Windows Live, there will be no cross-platform play between the Xbox 360 and the PC. However, Gears of War will run on Windows XP as well as Vista. Multiplayer on the PC will also include three new maps along with the 16 included in the original release, as well as a new "King of the Hill" game type.
Unfortunately for Xbox owners, Epic isn't planning on bringing the new PC content to that platform. "There is no plan to provide the PC exclusive content to Xbox 360 gamers for a number of technical reasons," Fergusson said. "One is simply the size and scope of the new content which would be difficult to deliver as an update. But more importantly, Gears of War for Windows was not created with the same version of Unreal Engine 3 as Gears of War for 360. We wanted to take advantage of all the latest and greatest optimizations and features that are constantly being added to UE3, and as such, this new content is not easily compatible with the Xbox 360 version." There is also currently no way to bring PC-created game levels to the Xbox 360.
