No Power
Not a third chapter. A toggle in the lobby that strips the lighting out of whichever chapter you were going to play anyway.

It applies to both chapters
There are two No Power badges, one per chapter, which is the cleanest proof that this is a modifier rather than its own map. The official VIP pass says the same thing from the other direction — it grants “Infinite Lives in Escape and No Power”, naming them as two states of the same thing rather than two maps.

Turning the lights off costs roughly twenty-three out of every twenty-four completions in the school. That is a far steeper penalty than the wording “no power” suggests, and it is the strongest argument for learning the room layout in the lit version first.
