Backrooms: Monster Merge

About Backrooms: Monster Merge: Collect and Merge 60 Terrifying Entities

Backrooms: Monster Merge drops you into the unsettling corridors of the Backrooms, where you collect, merge, and battle with its most dangerous inhabitants. The goal is to discover all 60 monsters lurking across the different levels — named entities like Smiler, Pirate Clark, and Many-Arms are among the creatures waiting to be found. Every two levels, a new location opens up, pulling you deeper into the Backrooms.

One scene shows yellow-tinted hallways lined with fluorescent ceiling lights and beige walls, with various characters set against that backdrop. Another scene reveals a dark room filled with rows of black metal bunk beds and exposed ceiling pipes.
