The Backrooms: Mass Extinction

The Backrooms: Mass Extinction is a survival game set in the Backrooms, an endless purgatory of damp carpet, mono-yellow rooms and buzzing fluorescent lights. You enter it by noclipping out of reality in the wrong place, and find no one left to help you.

Explore the levels

You can explore a massive Level 0, a maze of non-Euclidean rooms that stretches infinitely in every direction, along with its sub-levels and other Backrooms areas. These include Level 0.2, called Remodeled Mess; Level A, the Poolrooms; Level 0.3, Level Fun, home to the Partygoers; and Negative Levels. The Manila room is hidden behind a wall you can noclip through, and books document the levels.

Survive the Backrooms

You collect items, including Almond Water, and use vending machines to avoid dying of hunger or thirst. A torch helps you light dark areas, but you need to keep enough batteries on hand. You can also find hidden weapons to use against entities.

The current entity types are Partygoers, Smilers and Hazmat entity. Options let you disable entities, play with guns to defend yourself and choose a difficulty.

Play modes

You can play on desktop or in VR, and switch between the two modes. The Poolrooms water is interactive in both modes, and in VR you can splash it with your controller.
