GRIMBUS is a 4-player online co-op horror-comedy loot-extraction game coming to Steam for PC. You and up to three friends are a salvage crew working for a shady company. A rusty, armoured yellow bus drives you to creepy abandoned dungeons hidden in hillsides – desert dunes, jungle, frozen ice fields and an old quarry.
Sneak through dark, twisting rooms with a flashlight, grab whatever looks valuable, hide in lockers when something breathes nearby, and haul everything back to the Vat at the back of the bus before the timer runs out. Hit the quota over three drops, or meet management.
Play solo or host up to three friends online. Walkie-talkies are standard issue. Friendship is optional. The quota is not.
Sneak through dark, maze-like dungeons that grow new floors the deeper the run goes. Grab everything and haul it to the Vat before the timer hits zero.
Flashlight off. Locker door shut. Breathe quietly. Actually, don't breathe at all. Some monsters see you, some hear you, one just wants your stuff.
Miss quota over three drops and the company sends a flying saucer to tractor-beam your bus into a mountain. Performance review: complete.
Vehicle inspection // fails most categories
The GRIMBUS is a rusty armoured school bus with a plough, a roof rack and a ramp that drops at the dungeon door. It's how you get to the job, where you count the loot, and the only thing standing between you and the dark. Killed a monster? It drops a soul. The bus buys souls. Don't ask.


Dump your loot in the glowing green Vat at the back of the bus. The quota meter does the judging.

One seat. Four opinions. Fight about it on the way.

Three gauges, five buttons, zero manuals.

Pull it to leave. Count heads first. Or don't.

Company HQ. A cavernous garage with a painted bus bay, a cork board full of bad news and a hanging lamp that has seen things.

A roadside shop for flashlights, batteries and med kits. Spend your cut wisely. Or on hats.
Job sites // hazard pay not included
Every drop is a maze of modular rooms – corridors, junctions, loot rooms and a locked vault – built from chunky low-poly 3D models with crisp pixel-art textures. Runs start on one floor and add more as you go, with plenty of places to fall.

A buried tomb under the dunes. Sandstone corridors, sarcophagi and a vault full of things the pharaoh specifically asked you not to touch.
Loot: Golden idols, pharaoh masks, scarab amulets
Mossy temple halls swallowed by the jungle. Rope bridges, hanging vines and a stepped altar that is definitely not a trap.
Loot: Jade frogs, emerald skulls, tribal masks
An abandoned research bunker and mine dug into the ice. Frosted lockers, mine carts and a computer bank still blinking.
Loot: Snow globes, yeti teeth, frozen fish
A quarry works with conveyor halls, filing rooms, locker rooms and a steel vault full of deposit boxes nobody came back for.
Loot: Deposit boxes, tools, copper wireHazard register // known residents
Company policy is to avoid these. Company policy is also to hit quota. Good luck. Hover or tap a photo to turn the lights on.
Hangs out in the dark with a little light on its head. That is not a reading lamp.
Wrapped in bandages. Unwrapped in anger.
Lives under the floor. Loves footsteps. Loves yours specifically.
An empty hood with a very full schedule of haunting.
Screams to tell its friends where you are. It has a lot of friends.
Made of stone. Takes its job extremely seriously. Unlike you.
Rooted to the spot. Its roots, however, are not.
Thin, cold and very, very patient.
Wears a hard hat. Follows zero safety guidelines.
Reports from crews who made it back. Mostly. No clear photos exist.
Follow the pretty light. Everyone does. Once.
Doesn't want to hurt you. Just wants your stuff. All of it.
Stares until you look away. Then it does cardio.
Can't see you. Can hear you breathing. Has a laser.
Terrible handicap. Excellent swing. Yells FORE as a courtesy.
4.5 metres of "you should've left by now."
Inventory manifest // handle with care
Every zone has its own treasure, from golden idols and jade frogs to snow globes, frozen fish and one very important bowling trophy. The company buys it all. The company pays very little.
















Personnel files // dress code: optional
Every salvager gets goggles, overalls and a name tag floating over their head so your friends know who to blame. The rest is up to you.

GRIMBUS is a 4-player online co-op horror-comedy loot-extraction game for PC. You and up to three friends are a salvage crew for a shady company. A rusty armoured bus drops you at haunted dungeons in the desert, jungle, frozen ice fields and an old quarry. You sneak in with flashlights, grab loot, avoid monsters and haul everything back to the Vat on the bus before time runs out.
GRIMBUS does not have a release date yet. The game is in active development (alpha). Join the crew list on this page to hear first when the Steam page, playtests and release date are announced.
GRIMBUS is being made for PC and will release on Steam.
One to four. Play solo, or host an online co-op game for up to three friends.
It is spooky, but it is also silly. Think dark dungeons, flashlights and monsters that sprint at you, mixed with propeller hats, a yeti in a hard hat and a monster that yells FORE.
If you enjoy co-op loot-extraction horror games like Lethal Company, R.E.P.O. or Phasmophobia, GRIMBUS is built for you. Its own twist is a rusty armoured bus that is your ride, your base and your bank, plus a company that sends a flying saucer when you miss quota.
You get three drops to hit the quota. Miss it and the company sends management: a flying saucer that tractor-beams your bus and throws it into a mountain.
Playtests are planned. Sign up on this page to get an invite when they open.
