With the release of the Call of Duty: Black Ops 3 Salvation DLC expansion pack comes Black Ops 3’s final Zombies map, Revelations. One of the first things you’ll find yourself tasked with in Revelations is turning the power back on. This should come as no surprise, as you were required to turn the power on in previous Black Ops 3 Zombies maps.
Keep in mind, this step is critical for players who wish to use the Pack-a-Punch machine later on and is a required step in several Easter Eggs. Fortunately, turning the power on in Revelations is a pretty straightforward process and can be done in a few simple steps. In this guide, we’ll explain how to override the four corrupt engines in order to turn on the power in Black Ops 3 Revelations!
How To Override The Four Corruption Engines
Similar to the power generators found on the Origins Zombies map, there are four ritual generators strategically placed throughout the Revelations Zombies map that must be activated to turn on the power. These generators are called “Corruption Engines” and each one requires a manual override to become activated. The Corruption Engines feature large glowing spires, which makes them pretty easy to spot. Each will have a small ritual table out front in the center of a circular arena surrounded by pointed rocks.
There are also four triangular pillars along the outer edge of this area. Approach the back of the ritual altar and spend 500 Points to override the Corruption Engine. You’ll repeat this process at each of the four ritual locations to turn on the power for the Tesla device. The override will activate the spire, causing electricity to flow to its outer pillars. A series of Keepers and creatures will also spawn in for a few seconds so prepare yourself. Hold off the enemies, and wait for a portal door to open behind the ritual table.
Upon overriding a Corruption Engine, an icon will light up on the nearby map diagram to help you keep track of which of the four ritual areas still require activation. There are four Corruption Engine ritual areas found in Revelations, and you’ll have to unlock the various classic map locations to find them.
Revelations Corruption Engine Locations
Corruption Engine 1: The first Corruption Engine can be found in the starting area straight ahead from the initial spawn location which makes it pretty hard to miss. Activating this generator opens up a portal door to Nacht Der Untoten, acting as the central hub between each of the other classic map sections. Follow the wires from the Tesla Death Ray panel upstairs to determine which portal door to enter next.
Corruption Engine 2: The second Corruption Engine is found within the Der Eisendrache map section, not far from the pyramid. Repeat the same steps to override the generator, and be prepared to eliminate the wave of enemies that spawn.
Corruption Engine 3: The third Corruption Engine is found within the Verruckt map section. Go through the first door on the left to find the ritual area and override the generator.
Corruption Engine 4: The final Corruption Engine is located within the Mob of the Dead map section. Pass through the underground corridor in Mob of the Dead and head downstairs to the area with the metal platforms. The ritual area will be on your left.
Activating all four Corruption Engines will turn on the power for the Tesla Death Ray, which is located upstairs in Nacht Der Untoten near the Juggernog vending machine. From here, you can access the Tesla panel and continue onward to reach the Pack-a-Punch machine in Revelations.
