Unknown Rules

Unknown Rules is a first-person horror puzzle game. You play as an ordinary worker who falls from a Frontroom into the Backrooms, completing tasks alone or with friends and facing an unexpected journey.

Frontroom levels

You can select one Frontroom level, and both lead to Backroom Level 0. In the Office, you are an office worker who stays late, falls asleep at your desk and wakes to find the surroundings changed. In the Logistics Warehouse, you work the night shift retrieving, packing and shipping orders; after completing your quota, you find an unsettling note.

Backroom levels

Backroom levels unlock progressively and cannot be selected freely. The levels described are listed for reference, not in gameplay order. They include:

• Level 0: The Darkroom: procedurally generated terrain.
• Level 37: Sublimity: a serene poolcore environment designed for multiplayer.
• Level 9: Suburbs: a windswept, sinister suburban setting.
• Level 1: Abandoned Public Zone.
• Level 6: Lights Off.

Items and survival

Your inventory has 8 backpack slots and 2 pocket slots. You manage stamina, sanity and health, and use found items to survive and solve puzzles.

• Energy Drink: temporarily boosts stamina.
• Sanity Pills: stabilize your mental state.
• Batteries: restore power to electronic devices.
• Mysterious Notes: provide clues for puzzles.

Stamina is limited and important during escapes. Encounters with the supernatural wear down your sanity, while injuries are survivable unless caused by overwhelmingly powerful entities.

Party mode

Two experimental party maps offer activities beyond the horror levels. In Level 1: Go Parlor, you can play a full match of Go against a friend while listening to music. Level 2: Cinema lets you watch together using a video URL; basic playback works, though its features are incomplete.
