Game Overview

The Backrooms: Mass Extinction Demo immerses players in a surreal and unsettling world where escaping reality through a glitch, or "noclipping," traps you within the eerie confines of the Backrooms. This liminal space is characterized by endless, monotonous yellow rooms, damp carpets, and the constant hum of fluorescent lights, creating a haunting atmosphere of isolation and suspense. As you navigate the maze-like environment, you’ll encounter several distinct areas to explore, including Level 0 with its infinite, non-Euclidean corridors, the sub-level known as “Remodeled Mess,” the mysterious Poolrooms of Level A, and the Habitable Zone. The demo offers a glimpse into this vast, unnerving universe, setting the tone for the full game’s expansive exploration of multiple levels and hidden sub-areas. Gameplay revolves around survival and exploration, with players managing resources like food, water, and battery power for their torch to illuminate dark passages. The game features an inventory system for collecting useful items such as Almond Water and hidden weapons to defend against hostile entities like Partygoers, Smilers, and Hazmat figures. Players can choose to engage with these threats or disable them for a more relaxed experience. The game supports both desktop and VR play, allowing seamless switching between modes, with interactive elements such as splashing water in the Poolrooms enhancing immersion. Progression involves uncovering secrets, finding hidden rooms like the elusive Manila room, and piecing together the lore through scattered documents. Built on Unreal Engine 5, The Backrooms: Mass Extinction offers a tense, atmospheric journey through a surreal nightmare that challenges both your wits and nerves.
