Rip Off - MAME - Shoot 'em up

RIP OFF is a 1- or 2-player action game that offers features guaranteed to capture and prolong player interest: an accelerating competitive level with a clearly visible object and a team competition option that allows players to combine scores as well as skills in defense strategy against a futuristic enemy. The center of the playfield is occupied by a selectable number of triangular fuel cells that pulsate with radioactive energy. The player commandeers a land craft that turns left, right, accelerates and fires torpedo energy bursts activated by push-buttons mounted on the "bridge" control panel. All is quiet as the background audio repeats an ominous low frequency tone. Suddenly, alien craft enter in waves from the edges of the playfield attempting to attach their vehicles to the fuel cells and drag them off to restock their own dwindling supplies. The player maneuvers his land ship into position and fires a volley of torpedoes at the first invader, causing his vehicle to explode in a thunderous roar and a flash of light. A second invader retaliates by firing short range laser bursts at the defender ship while a third invader escapes, dragging off a precious fuel cell. The background audio quickens its pitch and tempo as another wave of sleeker, faster invaders attack and maneuver to rip off fuel canisters - and the battle rages on!
