Space Station 13 is a community developed, multiplayer round-based role playing game, where players assume the role of a crewmember on a space station. Together they must keep the station running smoothly, whilst dealing with antagonistic forces who threaten to sabotage the mission.

At the beginning of each round, players select a crew member role on the station. These range from high up positions like the captain and heads of staff, to engineers, scientists, medical doctors, security officers, all the way down to the lower responsibility roles such as the janitor and lowly assistant. At round start, one or more players will be given an antagonistic role at random, and a secret objective that’s very likely to cause disruption to the mission at hand.

When the crew aren’t turning on each other through sheer paranoia, they will face various dangers depending on the round: Sleeper agents hell bent on sabotage, shape-shifting aliens, RPG toting syndicate operatives and more. Not to mention the occupational hazards of working in space, such as decompression, meteor showers, radiation storms, airlock mishaps, rogue AI and catastrophic engine failure.
