Phantom of the Asteroid

A giant asteroid is heading toward Earth, and the only way to destroy it is to find 36 uranium cubes and gather them in one place. You are equipped with a jet-pack which you use to navigate the asteroid, but it has a limited amount of fuel, and when it is running low, you need to refill at the fuel depots scattered around the asteroid. Your oxygen also depletes, but you can restock on this as well.

Your task of finding the uranium cube is made hard by three types of force fields, which block different sections of the asteroid. Each type can be deactivated for a different period of time by standing on their respective control pads. To make matters worse, creatures known as Phantoms know about your task and will home in on your location. The only thing that they do is disappear upon contact, draining your energy in the process. Like oxygen and fuel, energy can be restored by finding energy depots.

Other hazards to be on the look out for include fire, spikes, and poisonous plants. If you make contact with any of these, the game is over. Once you have found all the uranium cubes and gathered them in one place, you have five minutes to reach the teleport and escape before the nuclear explosion blows up the asteroid. You can save and load games anytime during the game.
