The Xbox 360 lineup will be led by "Gears of War 2," which was shown to reporters at Dogpatch Studios in a demo controlled by the game's lead developer, Cliff Bleszinski of Epic Games. The game might not be done, but the talking points are far along.

Bleszinski reminded reporters that the game was "bigger, better and more badass" than its predecessor several times. To prove it, he controlled returning protagonist Marcus Fenix in an early level of the game. Bleszinski had Fenix standing on top of a rolling derrick, one of several massive flatbed trucks rolling toward a goal in the midst of a war zone. From all sides, giant cannon-backed monsters approached the truck to attack Fenix. Hundreds of locust foot-soldiers swarmed the trucks. Fenix hopped on and off the truck to blow every last one of them to bits.
