Traitor Mode is a mode in which a lone Syndicate Agent aboard Space Station 13 must complete a specific objective given to him and then escape from the station. The crew must find out who the Traitor is and arrest or eliminate him.
Traitor objectives are usually one of the following:
- Hijack: Hijack the shuttle before it reaches the station, or escape on the shuttle alone.
- Assassinate: Assassinate a specific crew member. They are usually in secure posts, such as Toxin Researcher or Engineer.
- Slaughter: Kill everyone on the station.
- Sabotage: Eject the engine from the station.
- Steal: Steal a paticular item. Usually a Flashbang, Plasma Flask, Plasma Tank, Sleep Toxins or Sleeping Pills.
The AI can also be a traitor. It is usually required to force an evacuation of over 50% of the crew, or to kill everyone.
