The year is 2089. A collision with a comet has left the earth reeling from radiation poisoning. There's little hope for humanity's survival. It's up to you to rescue the few remaining people. You must leave the protective fortress Albagon and deliver the newly developed radiation vaccine to the survivors. Your journey will not be an easy one. Nefarious henchmen are waiting to knock you off and steal the vaccine to ensure they will survive to rule the planet. Replenish your weapons, armour, and fuel in the cities - if there are any survivors to sell you supplies.
You must then find the rocket poised to launch a satellite that can nullify the effects of this cosmic accident that turned the world upside down. If you are sharp enough to learn the secret code words and live long enough to use them, you can launch the rocket and save the world.
