See Hall (disambiguation) for other related uses.
The power hallway is a location and one of the many Level K rooms from Chapter 3 of Bendy and the Ink Machine. This is where the first Butcher Gang enemy, Piper, is encountered. It appears to be a breaker room, as apparent from the presence of power switches.
The power hallway appears to be a breaker area, given the power switches in the area.
The hallway is connected between the toy storage and the entrance to Level K.
When Henry enters this location, he will need to pull both of the levers at the same time to activate the door. Henry tells Buddy Boris to get the one closer to the door, and then Henry goes to the other switch. Before he gets to the lever, Piper pops out of the "The Butcher Gang" poster. Henry cannot pull the switch until he finishes Piper off.
