In a secure facility gone dark, you and a partner must solve cryptic puzzles, uncover hidden truths, and survive unearthly anomalies. Cooperation is your only hope, trust is optional.

I wake up to silence. The hum of the containment doors is gone. No alarms. No guards. Just flickering lights and the smell of ozone in the air. The last thing I remember is… running. Now the facility is wide open, and the anomalies are moving freely.Somewhere in the dark, my partner’s voice crackles through the comms. Together we’ll have to restore systems, piece together what happened, and contain whatever escaped. Every corridor is a puzzle, every control panel another locked door between us and survival.We share scraps of information, sometimes by choice, sometimes because the system forces us to split up. I never know if my partner is telling me everything. Maybe they are saving themselves. Maybe I am.The walls groan. The lights dim again. I hear footsteps that aren’t mine. If we can solve the puzzles fast enough, we might keep the next breach from happening. If not… we’ll be the next file in the archive.<h2 class="bb_tag" >Features</h2><ul class="bb_ul"><li>Play in tense online co-op</li><li>Solve layered environmental puzzles that demand communication and timing</li><li>Explore the SCP Foundation facility from abandoned labs to locked research vaults</li><li>Experience a reactive story shaped by your actions, trust, and survival</li><li>Encounter anomalies that adapt to your choices and the facility’s systems</li><li>Multiple endings and hidden truths to uncover across replays</li></ul>
