G-Nome

In the future, an uneasy peace exists between four races. The Humans, the Darken, the Merc and the Scorp. The Scorp are developing a highly powerful weapon, and it's your job to sneak behind enemy lines to figure out what's happening. You do this in your giant robot, called an HAWC (Heavy Assault Weapons Chassis). One big advantage your HAWC has is you can easily eject. You can fight on foot if you want, but then again, you can also steal other people's vehicles.
