Metaldrone

You are the METALDRONE, the latest in a series of war-droids. To test your ability, you have been placed on the Cybasphere Assault Course, an artificial course which consists of 10 levels.

To complete a level, you must find a disk, shoot the Cybasphere Leader (the Leader will appear in a certain room on each level from out of a "generator"), pick up the missile disk that he will drop, fire the missile at the level's exit door, and go through to the next level.
