From the blurb:
Owned and operated by RA-Industries, Cleopatra Station is a small, wheel space station that orbits around Mars's fast moving Phobos moon. This is a long-term lab that conducts experiments in the genetic mutation of Crain, a corn-like grain substance that grows very well on the dust plains of Mars. It is the home of several scientists and their families. Howver, all communications with Cleopatra Station have simply ceased. RA-Industries needs to find out if there is a problem, and your X-plorers team is just right for the job.
Cleopatra Station is a short sample mission. This mission is designed for 3-5 player characters of first level, and will take about 2-4 hours to complete.
