In honor of the shopping madness that is just four days away, we are running a three-for-one news special today without the need to be at a store at 5am. It's because we care. First and foremost, we have just announced that there were be a Halo 3 map pack releasing on December 11th. From the media alert: Available for 800 Microsoft Points exclusively on Xbox LIVE Marketplace, each map presents a totally different play style. Standoff’s symmetrical valley, with its entrenched bases and fields of boulders is ideal for mid-sized objective and Slayer game types, while Rat’s Nest’s vast, labyrinthine passages bring something new to the “Halo” multiplayer experience: an indoor vehicle paradise, strongly influenced by the Campaign mode, ideal for big team battles. Finally, Foundry is the ultimate Forge map – players can edit every single object in this voluminous industrial warehouse, place stairways, walls, bridges and tunnels to create an entirely new play space and build almost any kind of map they can think of. And coming out this Wednesday on Xbox LIVE Arcade is Undertow.
