Sega Master System / Mark III / Game Gear
As the name suggests, this is a 3D electro-specs game, which puts you in the middle of a naval war. Sink as many of the patrol boats and battleships zooming across the horizon as possible, and zap any aircraft swooping overhead.
The hostile sprites don't whoosh out of the screen, and the 3D specs only provide the illusion of ships zipping across he screen at different distances from the player. The action is quite basic, shoot 'em up stuff too, so all in all, this isn't a particularly stunning game, even with the added dimension.
