Metal Storm (Nescube) Java Game

Metal Storm's stage 6 boss fight, the battleship from stage 3
M-308 Gunner robot that you control can reverse gravity at any time. It turns a fairly good action-shooter into an altogether unique game, as Irem puts the idea through its paces by sticking that tubby little robot in both traditional blast-everything environments and more demanding puzzles. Its short but fairly tough, and, like the best old-school games, fun simply to screw around with.
