The "Halo 3" Heroic Map Pack has launched on Xbox 360's Xbox LIVE Marketplace.

More than five million "Halo 3" players worldwide can now enjoy a package of three all new multiplayer maps. The Heroic Map Pack is the first in a series of downloadable content from Bungie Studios.

Available for 800 Microsoft Points exclusively on Xbox LIVE Marketplace, each map offers a unique experience.

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.

The maps of the Heroic Pack are available in matchmaking to those who have purchased the download.

If you're really short of cash, then all three maps will be available as a free download via Xbox LIVE Marketplace, but not 'til Spring 2008, just prior to the next wave of all new "Halo 3" multiplayer maps.
