Space: Zotaxian Ruins

Two astronauts have crash-landed on a desolate planet whose surface is covered with the ruins of an ancient civilization. The white spaceman attempts to repair the ship, while the yellow spaceman explores the ruins. However, a surviving Zotaxian (the aliens from the UFO and Inscectoids theme) has spotted them, and is not benevolent. While the yellow spaceman falls through a trapdoor, the white spaceman and the ship are captured by a shadowy creature. Will either of the spacemen make it out of the ruins and back into the twinkling stars?
