Doomsday Bunker Murder Mystery Party
Sealed doors, rationed water, and a survivor who did not survive the night.
5-12 players, sweet spot 8 · the full kit is ready in about 20 minutes. Or name your guests and see who they play, with the opening scene, free in about 30 seconds.
The blast door sealed nine days ago. Inside: a billionaire's prepper bunker built for twelve, with hydroponics, a generator, a radio that only picks up static, and a stockpile of canned peaches. The survivors are the owner's family, the engineer who built it, a doctor, a stranger who got through the door at the last second, and the security chief. There are rules about rations. There are rules about the door. This morning, one of the twelve bunks was empty and the oxygen scrubber has not been touched.
Playing it feels like a pressure cooker with the lid welded on. There is nowhere to go and nobody to call. Everyone is rationing, everyone is scared, and everyone has a reason to want one fewer mouth to feed. Clues hide in inventory logs, the generator room, and the medical bay. Accusations arrive with cabin fever. Your kit gives each guest a survivor, a secret, and clues to follow through the tunnels. The reveal decides who stays sealed in with whom.
Perfect for
A strong choice for corporate team building, Halloween parties, and friend groups who love survival games, and a favourite with teams that enjoy a bit of pressure.
Cast size
5-12 players, sweet spot 8. Every kit is written for your exact headcount and gender mix, so nobody doubles up and nobody sits out.
Who is at the party
A taste of the cast a doomsday bunker kit produces. Your mystery is written fresh, with its own suspects, secrets, and one guilty guest.
The Bunker Engineer
Designed every system down here, knows how to bypass the door lock, and has not been sleeping in the assigned bunk.
The Owner's Spouse
Married into the bunker, controls the ration keys, and has been counting supplies with a different number than everyone else.
The Last-Minute Stranger
Got through the door with seconds to spare, has no paperwork, and knows the layout suspiciously well.
The Security Chief
Was hired to keep everyone safe, carries the only radio, and has been receiving a signal nobody else can hear.
Setting the scene
Costumes
- A grey boiler suit or coveralls, work boots, and a headlamp for the engineer who keeps the lights on.
- A cardigan over a sensible blouse, a lanyard of keys, and reading glasses for the person in charge of the pantry.
- A camo jacket, black beanie, and a walkie-talkie on the belt for the security chief.
- Scrubs or a white coat with a stethoscope for the doctor with a very well-stocked medical bay.
- Layered mismatched clothes, a backpack, and dirt on one cheek for the stranger who came in from outside.
Food and drink
- A ration spread served in labelled tins and foil packets: crackers, cheese, beef jerky, and canned peaches.
- Hot instant coffee and powdered lemonade, the non-alcoholic bunker bar.
- A last bottle of whisky decanted into a jar and served in tin cups, poured by the person with the ration key.
- A one-pot chilli or stew served from a camping pot with a ladle, because the galley has one burner.
Atmosphere
- Cover windows with foil or black bin bags, kill the overheads, and light the room with lanterns and one flickering LED.
- Tape a printed ration ledger and a countdown-to-filter-change chart to the wall, updated each round.
- Playlist: low industrial hum and distant static, with a generator sputter sound effect to open each round.
- Stack cans, water jugs, and a first-aid box in one corner as the supply cache the accusations revolve around.
Host tip
Give the bunker a ticking clock. Each round, announce a new problem from the host guide: the generator dropped ten percent, the scrubber needs a part, the radio picked up something. Hand out ration tokens (poker chips work) and let players trade them for private conversations. Keep the lighting low and the door sealed. For the reveal, announce that the radio has finally reached the outside, and read the solution as the last log entry.

Questions hosts ask
Does the doomsday bunker theme work as a corporate team-building exercise?
Very well. Scarcity, trust, and negotiation are built into the setting, which makes it a natural fit for teams who want a game with stakes. Gather & Gasp kits run 4 to 20 players, print in about 20 minutes, and need no acting experience.
Is it too dark for a mixed group?
You control that. The customize step lets you set the tone from cozy to sinister, and at the cozy end the bunker is played for laughs about canned peaches and rota arguments. The kit never describes gore.
What props do I really need?
Almost none. Foil on the windows, a few lanterns, a stack of cans, and a printed ration chart sell the setting. The character booklets and the host guide provide the rest, including the clues that give the supplies a story.
