- "Consume the flesh and spice it well! Let the bones be burned!"
Corgan is briefly first encountered at the beginning of the game watching Blake as enters Temple Gate before backing away into the dark. Later on, as Blake stumbles into a room with a mangled corpse lying on a bed, Corgan lunges out at him from the dark and violently thrashes him around before shoving him down a staircase.
Corgan, along with several cultists, pursues Blake at walking pace through several buildings until Blake blocks Corgan off with some wreckage next to a doorway in a dormitory. However, Corgan quickly makes his way around and barges into the dormitory, forcing Blake to sneak his way out. After this, he is not seen again until the very end of the game, where his corpse is seen among the rest of the dead cultists.
- If the player is quick enough, it is possible to sprint up to and make physical contact with Corgan in The Crash while he watches Blake, which will result in him instantly killing him.
- On harder difficulties, an executioner will accompany Corgan in the dormitory, in which the former will enter through the basement.
