The latest in Krail War-Droid technology is to be tested on the toughest assault course yet built ... The "Cybasphere". It isn't easy, it would be beyond human ability, but the Metaldrone might just (and only just) make it! 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. - From the inlay.
