The human race is about to be without a home, Earth having been turned into a toxic wasteland by decades of war and centuries of neglect.

Now united and desperate to put down new roots, humanity sets off across the galaxy.

Good thing they have that miracle in the form of a team of 30-foot human-piloted battle robots known as the Mech Corps!
