'Gears of War 3' cinematic sets the scene

With the government in disarray and soldiers' outposts overrun by enemies, Gears of War 3's Lt. Anya Stroud introduces the game storyline in a new trailer.

The full game will be released for Xbox 360 on September 20 and, as well as wrapping up the current story arc, will institute four player co-op and an inverted take on the series' popular Horde Mode.

It's an early launch for one of the 360's biggest exclusives this year, well ahead of Forza 4 (October 11) and Halo Anniversary (November 15).

The PlayStation 3 goes with Resistance 3 (September 6) and Uncharted 3 (November 1); no-one really wants to go toe-to-toe with Battlefield 3 (October 25) nor Call of Duty: Modern Warfare 3 (November 8).
