Join the game Betrayal io as two options. Join as a crew member or as a traitor. The traitor will have to destroy every plan his comrades carry out, without being killed.
Crewmates
Both tasks must be accomplished without any members of the crew being injured. If you have a feeling that the traitor is, schedule a meeting and have a vote to evict them.
Betrayers have the potential to interrupt crew operations and kill crew members. There are vents that betrayers can use to get around unnoticed. As a betrayer, you must destroy all of your crewmates in order to win the game.
