The Underground Complex

Located below the Hawkins National Laboratory, this underground complex released dozens of interdimensional creatures in November 1984, before the rift was sealed.

The site kept some vestiges of its past as the mental health institute, including a moldy isolation tank used by patients suffering from acute anxiety that was later modernized for mind control experimentation on promising test subjects.

Now the walls of the abandoned facility are sprayed with bullets and blood, evidence of a battle against interdimensional creatures.
