A darkly funny bunker management sim. Build down, admit survivors at the gate and pray none of them is infected. Every night something new tests your layout: diggers from below, crawlers in the vents, spores in the air, screamers drawn to your generators.

About This Game



LET THEM IN. FIND OUT LATER.

The world ended on a Tuesday. You've got a hole in the backyard, a shovel and a line of strangers at the gate. Some of them are carpenters, cooks and nurses. Some of them are hiding a bite.

CHECK EVERYONE AT THE GATE

Look them over, take their temperature, read their papers and go through their bags. Then stamp it: Admit, Quarantine or Turn Away. Everyone has a story. Some of them are even true. Get it wrong and you'll find out days later, in the middle of dinner.

BUILD DOWN

Dig through soil and rock, pour concrete, raise walls and hang blast doors. Build dormitories, a mess hall, hydroponic farms, generators, air filters, water purifiers, a med bay and a quarantine ward. Start in a backyard shelter for six and work your way down to a ten-level mega-bunker for three hundred.

KEEP THEM ALIVE

Food, water, power, sleep, morale - and air. Every survivor breathes, and every generator is loud. Give people jobs, set the daily schedule and keep an eye on who's coughing.

EVERY MONSTER TESTS SOMETHING DIFFERENT

Walkers pile up at the door. Diggers tunnel up through the floor. Vent crawlers come in through the air ducts. Spore carriers poison the air. Screamers follow the noise of your generators. And some nights, everything comes at once. Your radio warns you before dark. Use the time.

HOLD THE NIGHT

Turrets, traps, sandbags, searchlights and guards with very little training. Combat runs on its own, and you can take control of your guards when it counts. In the morning, count the losses, patch the walls and open the gate again.

BREAK IT

In the sandbox, turn the threat up a hundred times and watch thousands of them press in round one hatch. Ring the yard with diesel trenches and light the lawn. Lay a field of blast mines and press the button. Then look at the whole bunker at once, ten levels deep, everyone in it going about their day. Photo mode hides the interface for the screenshot.

A DARK COMEDY OF THE APOCALYPSE

A clean isometric cutaway of a 1980s civil defense bunker: hazard paint, lamplight, CRT terminals and a shelter kit from a company that promises everything will be fine. It won't. But the monsters are cartoony, and nobody's insides end up on the outside.

WISHLIST NOW

Add it to your wishlist and Steam will let you know the moment the hatch opens.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Some of the game's art, such as the characters, objects, tiles and portraits, was generated with an image model from my own prompts and style guide, and I reviewed and picked every piece. I used an AI writing assistant to help draft the game's text, this store page and the trailer's captions, and I edited it myself.

Mature Content Description

The developers describe the content like this:

Cartoony violence: guards, turrets, traps, mines and fire fight off monsters, which end in goo and puffs of smoke, with no blood or gore. Survivors can die, shown in a cartoony way, and the dead are kept in a morgue. The story is about an infectious outbreak, and you decide who to let into your shelter. Children are never infected or harmed.
