// Phantom of the Asteroids(1985)

The earth is under threat from an asteroid hurtling towards it. Your mission is to destroy the asteroid and save the earth from invasion by a swarm of bloodthirsty Phantoms. To destroy the asteroid you must find and collect the 36 Uranium cubes on it. When these are gathered together in one place you will have 5 minutes (real time) to reach the teleport and escape before the nuclear explosion will blow up the asteroid. There are 3 types of force wall which will bar your way. The cyan, purple and green force walls are all of varying strengths but contact with any of them will result in instant death! Each type can be deactivated for a different period of time by standing on their respective control pads. Other hazards to avoid include the Phantoms who will slowly drain your energy and poisonous plants. To replenish your energy and oxygen stores you must find and stand on the supplies which are scattered all over the asteroid. Your mission is highly dangerous but not impossible! GOOD LUCK!
