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

It applies to every map
Every map has its own No Power badge, including the Play Place, which is the cleanest proof that this is a modifier rather than a map. The official Infinite Lives 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.
