Sinistar

A DOS remake of the arcade classic Sinistar, part of the "Williams Arcade Classics" series. Your task is to control a small space fighter and prevent some alien race from collecting enough Sinist crystals to create Sinistar - a giant spacecraft that would allow the aliens to capture the entire Universe. The gameplay is as follows: driving a fighter, you need to shoot asteroids, from which crystals fall, and collect them before the aliens. You should also destroy the alien ships to faciliate it - both crystal collectors and the warships that try to protect them.
