Escape on 13th: Species Unknown

You and your Expedition 1 crew are at your research station on a habitable planet, Ares. You have continued the time old search for signs of extraterrestrial life. Among the samples most recently brought back to the lab for analysis is a strangely smooth shaped stone. Not only do you and your crew discover the first alien life, but also find yourselves trying not to lose your own. There will be no rescue party; you're on your own. Will you survive?
