Dead in Space

It was supposed to be a simple rescue mission... what really happened was something else entirely.

A strange new alien life form has surfaced on an out of the way colony planet. The deep space research vessel Thanatos Rising has been sent to ascertain what it is and where it came from. They are too late. An infection has spread across the planet killing and changing everyone in its path. Is it related to the Alien or is it something else altogether?
