Auto Assault [GameStop Presale CD-Rom]

Auto Assault is an MMORPG with fast-paced combat in a post-apocalyptic setting. As a player, you choose to play one of three different factions; human, biomek, or mutant, and will spend most of your time inside your vehicle, fighting the surviving enemy groups and mutated creatures. Characters level up (with a max level of 80) and become stronger, gaining new skills and abilities and have access to a wide assortment of items due to the game's random loot generator. Vehicles can be customized in many ways, including paint colors, styles, and by adding new items and accessories.
