The aliens and their ships are smoothly animated, but when shot they never really explode. Instead, they're obfuscated by some ugly gray "clouds" that are supposed to resemble smoke - not very satisfying. Besides the changing scenery, there's little variety and the challenge is minimal. In terms of sound, a man's voice provides constant alerts and advice, but he's so muffled I can barely understand him. At least the game saves your high score. But in the end, Chaos Control is too shallow, especially now that its once-flashy graphics have faded.
