Space Attack

Space Attack is a shoot 'em up that mixes elements from a number of popular arcade games of its time. The player's task is to defend a city which, like in Missile Command, occupies the bottom part of the screen. The city is being attacked by aliens unleashed by a feared warlord who aims to fully destroy it. The aliens attack from above and move around in patterns similar to fixed screen shoot 'em ups like Galaxian.
