World's Edge

World's Edge is a text adventure game for the TRS-80.

Smog problems have reached critical proportions. The people of Earth desperately need 2.2 kg of APC-80 to absorb all of this air pollution. Spectrographic analysis indicates that this mineral is only available on Planet AW-8, orbiting Alpha Centauri. Inhabitants of AW-8 will try to prevent you from succeeding, for the mineral is central to their religious beliefs.

The player starts on their Earth farm, using their rocket ship disguised as a silo to land on the alien planet. There, they must explore the swamps and caves of wilderness on the surface of the planet to find their way into the city of Polarizon. Upon entering the city, the player must outsmart the local guards, steal the required crystals, and escape back to Earth.

All commands are via VERB NOUN commands, and there is a save and restore feature.
