Sega Master System / Mark III / Game Gear
Take your WWII fighter across land and sea, machine-gunning your way through oncoming enemy squadrons and putting the torch to battle ships and aircraft carriers. Extra help comes in the form of tiny wing-planes, which fire in different directions, and can be programmed to fly into troublesome enemies, kamikaze-style.
This is a one or two-ptayer conversion of an extremely obscure coin-op which was one of Sega's few arcade failures. The exceedingly bland gameplay is marred even further by blurred, flickering sprites and the "power-ups" are fairly pitiful, too. Unless you're really desperate for a vertically-scrolling shoot 'em up, this isn't worthy of consideration.
