Space Dungeon

Space Dungeon is a shoot 'em up arcade game released by Taito Corporation in 1981 and designed and programmed by Rex Battenberg. It was available both as a conversion kit and as a full arcade cabinet.

Like Robotron: 2084 (1982), but preceding the release of that game, the controls for Space Dungeon are a pair of 8-directional joysticks: one for moving, one for shooting. Space Dungeon is one of the first twin-stick shooters, after Taito's earlier games Gun Fight and Boot Hill.
