Play Space Mutiny Online — Sci-Fi Traitor Game Like Among Us

What Is Space Mutiny?

Space Mutiny is a sci-fi social deduction game for 4–12 players set aboard a deep-space vessel. The crew must complete critical repairs to save the ship, but one or more Saboteurs are working to destroy it from within. Through discussion, accusations, and emergency votes, the crew tries to identify the traitors before it's too late.

Think of it as Among Us meets a text adventure. Instead of running around a 2D map, you navigate ship systems through narrative choices, report anomalies in crew meetings, and argue about who tampered with the oxygen supply. The AI narrator describes sabotage events, system failures, and the growing tension as trust erodes.

Space Mutiny vs Among Us

If you love Among Us but wish the meetings were deeper and the accusations more strategic, Space Mutiny is your game. Here's how they compare:

Roles — Crew & Saboteur

Crew Members

• Engineer — Can repair sabotaged systems faster and scan ship logs for anomalies.
• Medic — Heals one injured crew member per round. A lifeline when the Saboteur strikes.
• Navigator — Tracks crew movements and can verify where players were when sabotage occurred.
• Comms Officer — Intercepts partial messages that hint at the Saboteur's next target.

Saboteur(s)

• Saboteur — Secretly damages ship systems each round. Wins by destroying the ship (3 critical failures) or eliminating enough crew to prevent repairs.
• Sleeper Agent — Starts as crew but is "activated" after a specific trigger event. Even they don't know they're a traitor at first.

Rules & Gameplay

1. 1

   Briefing

   Players receive role assignments and ship status. The AI narrator sets the scene: deep space, failing reactor, rising paranoia.

2. 2

   Duty Phase

   Each player chooses a ship section to work in. Crew members complete repair tasks; the Saboteur secretly selects a system to damage.

3. 3

   Incident Report

   The AI narrator describes what happened — which system failed, who was nearby, and any clues left behind. Tension builds as failures stack up.

4. 4

   Emergency Meeting

   Players discuss the incident. Who was in engineering when the reactor glitched? Why was the Medic in the cargo bay? Accusations fly.

5. 5

   Airlock Vote

   Players vote to eject a suspect into space. Majority wins. If the Saboteur is ejected, the crew wins. If an innocent is spaced, the ship gets closer to destruction.

Strategy Tips

As Crew

• Coordinate section assignments. If two people are in the same section, they can verify each other's innocence — or catch the Saboteur red-handed.
• Track sabotage patterns. If the reactor fails whenever a specific player is in engineering, that's not coincidence.
• Protect the Medic. The Medic keeps the crew alive through sabotage. Losing them early is devastating.
• Don't eject on thin evidence. Ejecting an innocent crew member is as bad as a successful sabotage. Be sure before you vote.

As the Saboteur

• Vary your targets. Sabotaging the same system repeatedly creates a pattern that leads back to you.
• Create alibis. Sabotage a section you weren't assigned to — if anyone asks, you were busy fixing comms.
• Accuse early and often. The most vocal accusers are rarely suspected. Point fingers before anyone points at you.
• Time your kills. Wait until trust is fraying, then strike hard — two rapid sabotages can end the game before the crew regroups.
