Halo 3 Heroic Map Pack

The Halo 3 Heroic Map Pack is already up for grabs via the Xbox LIVE Marketplace. You can download the whole pack or just one map at a time. Each map goes for 800 Microsoft Points. The three maps are: Standoff, Rat's Nest, Foundry. The Heroic Map Pack is the first in a series of downloadable content from Bungie Studios. Here's a rundown of what you're prepping to download, in terms of individual features for every map.

Standoff – a symmetrical valley: its entrenched bases and fields of boulders are ideal for mid-sized objectives and Slayer game types.

Rat's Nest – 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.

Foundry – 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 Forge also allows players to edit and customize all three maps, while Halo 3’s matchmaking playlists ensure that ranked and social gameplay remains dynamic and competitive. Xbox LIVE's Major Nelson reports that Bungie Games' Frank O'Connor has posted this FAQ on the map pack. This will answer any questions you have regarding the Map Pack.
