Heroic Map Pack

The Heroic Map Pack was announced on November 19, 2007. It includes three new maps, Standoff, Rat's Nest, and Foundry. It will be released on December 11, 2007. Available for 800 Microsoft Points exclusively on Xbox live Marketplace, each map presents a totally different play style.

Standoff
The symmetrical valley of Standoff, with its entrenched bases and fields of boulders is ideal for mid-sized objective and Slayer game types.

Rat's Nest
The vast, labyrinthine passages of the Rat's Nest bring something completely new to the multiplayer experience: an indoor vehicle paradise. Strongly influenced by the Campaign mode, this map is ideal for big team battles.

Foundry
Foundry is the ultimate Forge map. Players can edit every single object in this voluminous industrial warehouse, placing stairways, walls, bridges, and tunnels to create an entirely new play space and build almost any kind of map imaginable.

All three maps will become available for free download via Xbox live Marketplace in Spring 2008, just prior to the next wave of new Halo 3 multiplayer maps.
