A downloadable game for Windows

Please Read

We are not sure we will continue this project.


You wake up in a place you don't know.  You don't remember why you are here.
But one thing you are sure about, is that containment breach has occurred.
In the panic of containment breach and invasion of hostile forces, you will face conspiracy of the Foundation.


Dangerous creatures and hostile forces are coming to kill you! Can you get out of the facility alive?
This game has a lot of atmospheric, and terrifying scenes. They may be nostalgic for you if you've played SCP Unity long time ago.

Early Access!
