As a party game, we recommend playing with friends at a LAN party or online via voice chat.
The game requires one player to host, and supports 4 to 12 people playing at the same time.

The Astronaut

Objective: Complete all missions or discover all traitors!

If all traitors are expelled, or if all missions are completed, the astronaut wins!

• Astronauts need to complete a series of tasks on the spacecraft, including repairing equipment, cleaning the room, navigation control and so on.
  
• Missions help astronauts earn victory points, but also let others know what they're up to, making it easier to deduce the traitor's identity.
  
• Astronauts need to respond quickly to neutralize the traitor's sabotage.
  
• The ghost after the death of the astronaut can still continue to carry out the task assigned to him, and strive for victory for the astronaut camp.

The Traitor

Objective: Eliminate the crew or destroy the spaceship!

If the number of traitors is greater than or equal to the number of astronauts, the traitors win!

• Traitors need to sabotage the ship undercover, killing the crew and framing bystanders, causing confusion and suspicion.
  
• Traitors can pretend to perform missions to hide their identities, but they also need to avoid being discovered by others.

Emergency Meeting

• When the player walks near the corpse or the emergency meeting button, they can press the report button to call the entire astronauts for an emergency meeting.
  
• At this time, the player can tell who he suspects to be a traitor and what information he has. Traitors must try to prove their innocence, or accuse the other crew.
  
• A vote can be held in the meeting, and the result of the vote will determine whether to expel a player. The ejected player will be immediately thrown out of the airlock.
