Entity Research Group — a cooperative first-person horror game where you become part of a special unit investigating highly dangerous anomalous entities. Collect evidence and samples, complete technical objectives, and survive within the ever-changing Backrooms clusters.

Your mission is to locate, interact with, and investigate high-risk entities and carry out assignments in the zones of their activity.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/876ed14a3b3d9aebfcded8ff30bd9bf2.poster.avif?t=1769978767" width=1024 height=212 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/876ed14a3b3d9aebfcded8ff30bd9bf2.webm?t=1769978767" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/876ed14a3b3d9aebfcded8ff30bd9bf2.mp4?t=1769978767" type="video/mp4"></video><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/8972ddc4f0b73e601e2d73918af1668e.webp?t=1769978767" width=800 height=50 /> Expeditions: deploy into one of the Backrooms clusters and receive mission directives.Objectives: collect samples, document evidence, restore life support systems, rescue lost personnel and interact with anomalies.Data collection: use instruments, consumables, cameras and terminals to obtain and analyze information.Evacuation: return to the lobby via the evacuation elevator and complete the mission.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/fde01b8f3eb2d3d516903c3221ae114d.poster.avif?t=1769978767" width=1024 height=212 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/fde01b8f3eb2d3d516903c3221ae114d.webm?t=1769978767" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/fde01b8f3eb2d3d516903c3221ae114d.mp4?t=1769978767" type="video/mp4"></video><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/ae3a9c98a916f856c4c6676d71f180a4.webp?t=1769978767" width=800 height=50 />Procedural generation: each cluster is rebuilt, changing room layouts, objects and points of interest.Random events: power outages, gas leaks, acoustic and visual distortions.Mission variety: from photographing runes and symbols to operations to eliminate aggressive entities.Progression: an upgrade system unlocks new capabilities between expeditions and increases the difficulty of future contracts.Entity research: their behavior and effects are unpredictable, making every encounter unique.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/5c332cb9110569ea14c7e60511c2f1f1.poster.avif?t=1769978767" width=1024 height=212 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/5c332cb9110569ea14c7e60511c2f1f1.webm?t=1769978767" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/5c332cb9110569ea14c7e60511c2f1f1.mp4?t=1769978767" type="video/mp4"></video><img class="bb_img" src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4038080/extras/3a92657d936ceac41278a91330c14f47.webp?t=1769978767" width=800 height=50 />You will face a vast number of entity variants.
