One of Imagic's initial three offerings (along with Star Voyager and Trick Shot), Demon Attack is an excellent game in the ubiquitous "slide-and-shoot" genre. Players maneuver a laser cannon along the bottom of the screen, firing upward at waves of beautifully drawn and animated, bird-like alien creatures, some of which split in two (á la Phoenix).
As with so many shooters of its type, the action can get repetitive, but no matter -- the game is fun, the enemies are incredibly varied, and the sound effects are solid. There are 10 game variations, including Tracer Shots, in which lasers move in conjunction with your ship, and two-player modes, in which gamers alternate shots.
