Space 2096: The Invasion Begins

Space 2096: The Invasion Begins is a six-level PWAD for Doom II created by Dave Sherwin. The main theme of the mapset is that of exploring and boarding several UAC spaceships that have been taken over by demons before returning to the main starport back on Earth. The first two levels are cinematic and have no enemies in them, while the last level sets up the story as leading directly to MAP07: Dead Simple, as indicated in the .txt file and shown with the exit area.
