The title screen has some animation, showing how the Earth is incinerated, leaving behind mutated life in the Wasteland.
You create a party and move across the land, armed with crowbars, knives, and World War II era weapons.
You are free to look at and adjust your party as you need.
You can radio back to base to see if you are ready for promotion.
You spend much time cleaning up the planet of dangerous mutants.
Sometimes you help farmers, killing the dangerous "possums" in their fields.
