Exterios is an underground base deep down, 300 KM below the surface. The main hero awakes in healing capsule and sees that something terrible has happened on the base. Everyone is either dead or turned into horrible monsters. You will have to reveal the mystery of what happened in this atmospheric FPS with puzzles, and break free in the end.
