Dubium is a 5-player social deduction game set in a near-future sci-fi universe.

Players take on the role of Frontier or Traitor and must escape from an abandoned space station by any means necessary. Frontiers will cooperate to repair solar panels that power the escape pod while trying to uncover the identity of the sole Traitor.

Players must not relax until they escape; the Traitor will sabotage the Frontiers’ efforts at every step as they try to complete their own mission. The Traitor needs to hide their identity and use deceit and treachery to take the Frontiers out one by one in order to escape the station unopposed.

Everyone wants to get out alive. Trust no one!
