Outpost Erebus

In a distant future, mankind has spread across the stars. Prisons have been moved to far-flung remote world outposts. Erebus, an old outpost on Mars, now turned into a high security prison, has gone radio silent. A group of well equipped marines have been sent to investigate, suspecting a prisoner revolt. They soon realise there is a far darker truth behind the seemingly abandoned outpost. What started as a simple check-up mission quickly takes a turn for the worse and now the odds are stacked against the marines. Surviving outpost Erebus is going to test them to the core!
