"Five amazing games in one" boasts the cassette inlay... but "Five amazingly average screens in one" would be a little more appropriate. Cosmonut puts you in control of a little spaceman who has entered the maze-like head of an enormous robot. The mission is to destroy it by draining its power, a task requiring the completion of a series of three sub-games. When all are completed, the spaceman meets the robot for a final confrontation.

The graphics are very bland and sound isn't anything special. If a little more thought had been put into the sub-games, Cosmonut could have been fun, but the three games bear little repetition and quickly become predictable and dull.
