Backrooms  #999999999 Demo

Backrooms #999999999 is a singleplayer/4 player co-op horror exploration game. Unlock the puzzles, survive the entities, escape the deadly geometry and try to reach the final level in one piece. Good luck, wanderer!

Explore the infinite spaces beyond the reality you know, as you fall into the eerie levels of the backrooms.<h2 class="bb_tag" >Levels</h2>Each level has a unique aesthetic, the geometry is weird, yet somehow familiar, as if something tried to put it together, but that something is not human. You will have to traverse the spaces carefully, because the walls themselves will try to kill you.<br><br><span class="bb_img_ctn"><video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2785620/extras/0747a383e70467edcc011e4d8e1ad7e9.poster.avif?t=1762719210" width=544 height=230 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2785620/extras/0747a383e70467edcc011e4d8e1ad7e9.webm?t=1762719210" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/2785620/extras/0747a383e70467edcc011e4d8e1ad7e9.mp4?t=1762719210" type="video/mp4"></video></span><h2 class="bb_tag" >Entities</h2>Weird abominable creatures live here, and most of them want you dead.
