Boss Fighter features five different boss levels. The bosses range from everything from a destructive fighter jet to a robot which has gone haywire and wants to take over the world. To complete each level you have to perform a series of tasks and none of them (rarely) are never the same from the previous. This makes it a quite enjoyable map to experience.
Before entering each level there will be a brief introduction/story about the situation and also a hint what needs to be done. In some levels you will also find clues hidden on different places to indicate what you need to do to destroy the boss.
