Inside Project Darwin in Darwin Village, you must take Finster's Head to a room on the righthand side of the map. Using Cyborg tech on a disbanded character, that character is then transported to the Mind Maze. Once inside, this character will face a series of challenges as you proceed from room to room. You will face a few fights including the Night Terror, which if you can kill is worth 32,000 xp (double if you kill it in melee).
