You are a GATE employee working to expand the boundaries of human knowledge and explain the unexplainable, including various anomalies and paranormal phenomena: from gravity-warping artifacts to supernatural creatures with highly pronounced violent instincts. Security and secrecy are of paramount importance… most of the time.
A catastrophic security breach has turned your workplace into a cosmic battleground: anomalous entities roam free, enemies from other dimensions break through portals, and a secret military sect known as the Order indiscriminately attacks laboratories and staff in an effort to seize artifacts and eliminate the chaos.
Containment procedures have failed and there is no help on the way. You and your fellow scientists, trapped deep underground, must join forces to find a way to the surface, and until that happens, you will have to adapt to living in the subterranean complex.
