Characters

There are very few characters in Superliminal. The three main ones are Dr. Glenn Pierce, the Standard Orientation Protocol, and the Player.

Dr. Glenn Pierce
Dr. Glenn Pierce is presumed to be the creator of Somnasculpt and the head of the Pierce Institute. He first shows up after you escape the fake hallways and rooms in Chapter 2: Optical. He speaks to you through radios scattered around the rooms and hallways. Slowly, as the player makes their way farther into the dreamland, he stops needing the radios, and speaks whenever.

Standard Orientation Protocol
The Standard Orientation Protocol is a female-voiced AI who guides the player around the dream world and use the Superliminal perception abilities.

Patient Care Team
The Patient Care Team is referenced by the Standard Orientation Protocol and Dr. Glenn Pierce, however they never talk in the game.
