This guide shows how to turn on the Power on Blood of the Dead in Call of Duty Black Ops 4 Zombies (All Power Switches for the entire map). Turning on the Power opens up the rest of the Blood of the Dead map and makes the warden spawn who drops the Warden’s Key. There are 2 power switches that must be activated. Refer to the video below for the exact path.
Power Switch #1: RICHTHOFEN’S LABORATORY > MODEL INDUSTRIES > WEST GROUNDS > POWER HOUSE
Go through the areas as noted above and you’ll find the switch in the power house. You can see the area names in top left corner of the screen. Simply buy open the passages leading from one area to the next.
Power Switch #2: CATWALK > RECREATIVE YARD > CELL BLOCK ENTRANCE > D-BLOCK > C-D STREET > CELL BLOCK 3RD FLOOR > MICHIGAN AVENUE > CITADEL > CITADEL TUNNELS > CHINA ALLEY > BUILDING 64
Go through the areas as noted above and you’ll find the switch in Building 64. You can see the area names in top left corner of the screen. Simply buy open the passages leading from one area to the next.
After turning on the power, a heavy enemy called “The Warden” spawns outside the 2nd power room. Be sure to kill him for The Warden’s Key which lets you access other areas on the map. It can be charged up after crafting the zombie shield. Then you can suck the souls out of zombies with the key to unlock the Pack a Punch machine.
