After defeating Heskel, Shelly Harrison sits down for a well-earned drink at a local bar — until explosions interrupt everything.

Shelly grabs her Loverboy revolver, finds a high-speed armed Hover Bike, and pursues him through new zones with new enemies, new weapons, and high-speed vehicle combat.
