Assault City (1990)

Assault City is a light gun, rail shooter released for the Master System in 1990. There were two versions of Assault City released for it, the original version, which only supported the directional pad and a second edition which supported the Light Phaser gun. The two versions are distinguished by an image of a large red light phaser on the cover of the light phaser edition, though both cartridges appear identical. (wikipedia.org)
