Sineicos is a frozen planet located somewhere in the Gods Will Be Watching universe. According to Burden the place is dominated by the Medusa virus, and is home to various forms of life. Including "ghost like" predators that attack the player in the night, Jack is able to wound one of them during the assault. It seems as though various sectors of the planet get varying degrees of light, as the area the crew makes it's shelter only gets 5 hours of daylight.

The details of such life is unknown, however it is clear the food can be eaten raw without adverse consequences. Predators are described as "ghosts" by Donald, and make loud noises after their attack.
