The first of many Halo 3 map packs has landed itself on the Xbox LIVE Marketplace today. The Heroic Map Pack contains 3 maps and will set you back 800 MS points for now.

The Heroic map pack contains three new maps, each presenting 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 quite 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.

3 maps for $10? Pretty hard to justify that purchase if you ask me. Especially when Microsoft has already announced that these maps will be released for free this Spring. Patience is a virtue my friends.
