Map descriptions are as follows:
Sandbox -- Combines large-scale vehicular combat with a limitless amount of Forge customization. Boasting a tiered, open-world layout, "Halo 3" players will be able to build their own unique game experiences using the Forge map editor. Sandbox is a map unlike any Bungie has ever created.
Assembly -- Set in the heart of a Covenant Scarab manufacturing facility. With two identical bases on either side of this medium-sized map, it's a perfect environment for both Slayer and objective games like Capture the Flag and Assault.
Orbital -- A small asymmetrical map, is set in the docking station of the Quito Space Tether. One-sided games like One Flag, and One Bomb are sure to become quick fan-favorites, but the Slayer faithful will also find plenty of action on this battleground.
Now the bad news: If you’ve built up a great big grunty thirst that can only be slaked by the Mythic pack, and absolutely must own it on day one, you’ll have to toss your piggy bank at Halo Wars. Otherwise, you’ll be forced to wait until “later this spring” when the maps hit Xbox Live Marketplace.
The last time this happened, though, we got Crackdown, so we think we’ll take our chances with Halo Wars. How about you?
