Everyone knows the rules of the Backrooms: don't make noise, don't look back, and run when something starts following you. Backrooms with Guns throws those rules out. You walk into the yellow halls armed, and the things that live there are about to learn what it's like to be hunted.

You start with a pistol and a knife. The pistol turns a crowd of crawlers into a wet mess on the carpet, and when the magazine runs dry in the middle of the swarm, the knife finishes what the bullets started. Running out of ammo here just means the killing gets personal.

Each round the horde comes back bigger and faster, and each round you leave more of them on the floor. Spend the cash they drop on a progression tree: harder hits, faster reloads, ammo and medkit drops, new combat styles, and heavier hardware like Uzis and the AA-12 shotgun for when one bullet per monster starts to feel too polite.

Pick one of four heroes and carve a path from the Backrooms through the Office, the Hotel, the Parking garage and the Pools. Every zone throws more at you, bosses included, and somewhere in the dark the Smiler is waiting. It has scared plenty of wanderers to death. It has never met someone with a shotgun.

By the end of a good run, the yellow walls aren't quite so yellow anymore.
