Revelations:
Corruption Engines and Pack-a-Punch

How Revelations replaces the power switch: the four Corruption Engines, what an override costs and spawns, the Corruption Turrets, the Death Ray panel by Juggernog, and freeing the Pack-a-Punch from inside the Giant Apothicon. The House holds the first engine.

No power switch

Revelations replaces the power switch with four Corruption Engines, tall Apothicon machines spread over the islands. At the start of the game, a Giant Apothicon, an Elder God, has swallowed the Pack-a-Punch machine and circles the map with it. The four engines are the way to trap it and get the machine back.

The four engines

The House

In front of the church, in the starting area. Overriding it opens the church portal to Nacht der Untoten.

Der Eisendrache

In the Undercroft, near the pyramid.

Mob of the Dead

Outside the cafeteria. Overriding it also opens the door towards Origins.

Verrückt

Outside, past the 1250 debris from the ground floor.

Overriding an engine

  1. Pay: hold the action button on the engine, 500 points, so 2000 for the four.
  2. Hold: a small horde comes for the engine; survive about 30 seconds near it. During the first, second and fourth overrides of the game, Furies join the attack.
  3. Done: the engine is overridden for good, and a Corruption Turret can be used at it.

Overriding all four engines before round 6 earns the Controlled Chaos achievement.

Corruption Turrets

An overridden engine becomes a beam turret that a player mans for a short time, sweeping a laser over the area. Killing 40 enemies with one activation earns the Death Ray achievement. The beam can also bounce off glowing rocks on the platforms. During the main quest, the turrets shoot four floating blue rocks to bring Sophia back, which takes 8000 points in all.

Trapping the Giant Apothicon

The Giant Apothicon flying past the islands of Revelations, Call of Duty Black Ops III Zombies
  1. Override the four engines.
  2. Go up to Juggernog, on the top floor of Nacht der Untoten. The panel to its right lights up and buzzes when the Giant Apothicon flies past the electrical structures.
  3. Use the panel while it flashes: the Death Ray electrocutes the beast, which stays trapped next to Nacht der Untoten.
  4. Go down the stairs and walk into its mouth.
  5. Inside, shoot the yellow tubes on both sides of the sac that holds the machine. The Pack-a-Punch falls free.

Recovering the machine earns the Pack-A-Punch-ectomy achievement. An upgrade costs 5000 points.

Inside the Apothicon

A different look

Flesh walls, a pool of stomach acid and more skeletal zombies, which climb out of nine small doorway-shaped holes.

The resident Parasite

One Parasite always flies inside and comes back shortly after it dies. It does not count for the round.

Spiders

The only place on the map where they spawn, every three to five rounds.

Bosses on a timer

Keeping the last zombies of a round alive inside for about five minutes brings a Margwa of any kind or a Panzersoldat, even on early rounds, and again every five minutes or so.

Exits

To Mob of the Dead, Verrückt, Der Eisendrache and the House.

None of this exists in a First Room game: with the doors closed, only the House engine is in reach, and the Pack-a-Punch stays inside the beast.
