What is GRIMBUS?

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.

4-player co-op

Play solo or host up to three friends online. Walkie-talkies are standard issue. Friendship is optional. The quota is not.

Loot, then run

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.

Hide or die

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.

Meet the management

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 bus is your ride, base and bank

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.

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

The Depot – a big industrial garage where the GRIMBUS crew parks the bus between contracts

The Depot

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.

The Pit Stop – a roadside shop front with shelves of supplies and a street lamp

The Pit Stop

A roadside shop for flashlights, batteries and med kits. Spend your cut wisely. Or on hats.

Job sites // hazard pay not included

Four zones. Zero safety inspections.

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.

GRIMBUS FAQ

What is GRIMBUS?

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.

When is the GRIMBUS release date?

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.

What platforms will GRIMBUS be on?

How many players can play GRIMBUS?

One to four. Play solo, or host an online co-op game for up to three friends.

Is GRIMBUS scary?

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.

What games is GRIMBUS like?

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.

What happens if 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.

Will there be a GRIMBUS playtest or demo?

Playtests are planned. Sign up on this page to get an invite when they open.

How much will GRIMBUS cost?

Pricing has not been announced yet.
