You are the commander of the Rolling Refuge — a rolling fortress crossing the Rust Wastes. Your turret fires on its own. Drive to kite the scrap-beasts, vacuum up the scrap they drop, and spend it on plating, cannon, rapid-fire and magnet upgrades.
Survive all 10 waves. If your hull hits zero, the Refuge is lost.
