Backdoor Rupture

Painted concept art: D-0066 in an orange coverall fires a rifle across a yellow wallpapered room under fluorescent lights, casings flying, cigar smoke drifting.
Concept art, painted from renders of the finished model.

A fast, gore-heavy boomer shooter set in the Backrooms, with Lovecraftian and SCP elements. Endless roguelike runs through procedurally generated dimensions.

Eldritch horror all around you, and you are still the most dangerous thing in the room.

Pre-alpha. The player character is done. There is no gameplay yet.

You are D-0066: a D-Class convict in an orange coverall, with a number where a name should be.

You wake on the carpet of the Lobby next to a dead SCP soldier and a dead scientist. Nobody tells you what killed them. You take their guns and start walking.

Every run starts there: yellow wallpaper, damp carpet, fluorescent tubes humming overhead. Then it goes deeper.

The real model, on a turntable.

He never gets home.

That is the premise, not a spoiler.

If you have played

Quake 1 and 2
that is the feel.
Doom
that is the pace.
Risk of Rain 2
that is how the runs work: they go on until something puts you down.

What it is, and what it isn't

It is

  • A boomer shooter. Fast, loud, first person. You move like it's 1996, and anything that moves gets shot.
  • Gore. Whatever you kill comes apart. That is how you know the shot landed.
  • The Backrooms. Oppressive and indifferent. The place does not care that you are there, and that is where the horror comes from.
  • D-0066. Crude, and very good at this. He is flippant. The world is not.

It isn't

  • A story game. You get a situation, not a plot.
  • Quests. There are none.
  • Cutscenes. You wake up with control.
  • An ending. There is nothing to finish.

How he moves

Firing a rifle.
A two-handed swing.
Death.

Three of his clips. More are in the D-0066 file.
