About This Game

"Backrooms: Lethal Expedition" is an enthralling game that transports players back to the early 90s when scientists managed to unlock access to a new dimension code-named "Backrooms." As an explorer sent as part of a scientific expedition, you are tasked with delving into the depths of the levels of the famous creepypasta.

Your mission is to explore a multitude of levels, each promising new challenges and puzzles. The levels will be filled with a variety of puzzles, many of which pose a deadly threat. You must not only uncover the secrets of each level but also survive in this unpredictable and dangerous world.

Join forces with friends for collaborative exploration and puzzle-solving. Gather supplies, unlock new levels and try to collect everything you find along the way to strengthen your chances of survival. Embark on a lethal expedition to face the unknown and test your strength in the fight for survival in the backroom world.

In developing levels and entities, we are guided by the Backrooms Wiki/Fandom.
We are also inspired by the work of the talented artist Kane Pixels.
