On a dying planet where two rival clans battle over the last remaining crystals, the Hammerhawk seek to build a star-faring fleet to escape to a new world, while the Bloodfox intend to use the crystals to preserve their way of life, even if it means killing for it. Each clan's CD grants access to a design center where players construct their own forces from scratch. By choosing one of five chassis types, selecting a mode of transport—wheels, treads, hoverers, walkers, or flyers—and equipping exotic weapons, players assemble customized fighting machines meant to operate effectively together on the battlefield.
