Space Quest: The Lost Chapter (aka Space Quest 2.5) is a fan made sequel to Space Quest II: Vohaul's Revenge.

This previously unknown sequel in the Space Quest saga begins with Roger Wilco, our beloved hero, still floating in space after defeating Vohaul in SQ2. After who knows how long drifting in space, Roger's escape vessel is trapped by an unknown planet's gravitational pull and crash lands on the planet. The crash triggers the release of the sleep chamber that Roger is snoozing away in. He soon wakes to find himself still inside the escape pod, and also quite blonde!

After clearing his head, and exiting the chamber, Roger surveys his surroundings, finding that he has crashed on a planet that is heavily vegetated. He exits the pod and starts exploring the planet. In his explorations, Roger comes across many new forms of life, some of which aren't too happy to see him, but what's new?

Unbeknownst to Roger, aliens testing a weapon in nearby space were responsible for the crash. Having detected his escape pod and that one life form was aboard, they move to deal with the situation.

Back on the planet Roger is trying hard to stay alive long enough to get off the planet. Your job, should you decide to accept it, is to help Roger escape... or at least hope he finds edible plant-life so he can survive.
