THE FINAL REICH

Hold interact on each of the 3 pressure valves in the Village until the dial reaches 60 and turns green. Releasing early lets the pressure fall back down.

1. Village Square: behind the Armour station
2. Bunker entrance: to the left of the main door
3. Riverside: near the Pub entrance

Once all three valves are active, return to the circular device in the Village Square and interact with the Pilot Light. Flames erupt from the hole and several Pest Zombies climb out. Kill them, then drop into the hole.

Follow the underground path and interact with the generator at the top of the slope. This restores the main power and opens the Bunker door.

Open the main Bunker door and purchase access to both the Laboratory and the Morgue.

Activate both power switches within roughly one minute of each other. If too much time passes, the first switch resets and must be activated again.

• Laboratory: upper level, rear of the room
• Morgue: near the STG-44 wall purchase

Once both switches are active, return to the Command Room and open the large Salt Mine door. Proceed down through the Salt Mine into the Emperor's Chamber.

In the centre of the Command Room, hold interact on the large crank until it stops moving.

Travel down to the Emperor's Chamber and interact with the machine containing the Hilt, in front of Emperor Barbarossa's statue. A circle appears on the floor. Kill zombies inside it to transfer their energy into the machine. Once enough have been killed, the Geistkraft Transfer Device rises through the ceiling into the Command Room.

Return to the Command Room and climb onto the upper platform. Press the large red button to send the transfer device along the overhead rail. Follow it into the Laboratory: it will stop several times and create a red circle beneath itself. Kill zombies inside each circle until it moves again. When it reaches the generator beside Schnellblitz, wait for the first Tesla Gun part and pick it up.

The device continues on toward the Morgue. Keep following it and clearing the red circles. When it reaches the Morgue generator, collect the second Tesla Gun part.

Return to the upper platform in the Command Room. A Brenner will spawn. Shoot the fuel tanks on its back and kill it. Pick up its severed head; the Brenner Head is required later for the Voice of God puzzle.

Place both parts into the Weapon Forge on the upper platform and wait for it to finish constructing the weapon. In co-op, make sure every player collects a Tesla Gun before continuing.

Behind the Weapon Forge is the Power Grid machine. Interact with it and read the four numbered columns. Each shows one coloured light (Rot = Red, Grün = Green, Blau = Blue). Write the four colours down in numerical order. The combination changes between matches.

Visit the 4 power boxes under a time limit and set each one to its matching colour by interacting until the dial points to the right color. If the timer expires, return to the Power Grid machine to reactivate the puzzle.

1. Command Room: immediately to the right of the Power Grid machine
2. Sewers: on the fire-trap side of the Pack-a-Punch room
3. Sewers: at the opposite end, near the passage to Riverside
4. Pub: beside the door leading toward the Tower

Travel to the Tower and interact with the lever beneath its central structure. This begins a defence sequence and starts an enemy wave. Protect the lever until the Lightning Rod has fully risen and its health bar disappears. If the lever takes too much damage, the rod lowers and the defence must be attempted again.

Two more levers become available on the front-left and front-right supports of the Tower. Activate and defend both until the sequence is complete.

Return to the Emperor's Chamber and interact with the Right Hand of God, on the left side when facing Barbarossa's statue. This causes the hostile Zeppelin to appear above the village.

Bloodthirst:

1. Shoot the Sparking Streetlamp in Riverside with the Tesla Gun to move the spark to the next lamp. Shoot each sparking lamp with a normal weapon to keep moving it along until it reaches the bottom of the Morgue and the Battery falls.
2. Pick up the Battery and place it in the Device next to it.
3. Get Pest kills using the Trap in the same room until the Battery is fully charged.
4. Pick up the Battery and place it in the left slot of the Machine in the main Morgue room.
5. Interact with the Battery to start a defense. Defend it until it produces a Part to pick up from the Machine.
6. While holding a Tesla Gun, place the Part on the Bloodthirst Slot at the Tesla Gun Table in the Command Room to build it.

Hurricane:

1. Blow up a Bomber next to the Metal Panel in the middle of the stairs in the Laboratory near the Power Switch to reveal the Battery.
2. Place the Battery in the Device in the Electric Trap.
3. Kill 2 Wustlings at the same time with the Electric Trap, twice, to fully charge the Battery.
4. Pick up the Battery and place it in the right slot of the Machine in the Laboratory.
5. Interact with the Battery to start a defense. Defend it until it produces a Part.
6. While holding a Tesla Gun, place the Part on the Hurricane Slot at the Tesla Gun Table in the Command Room to build it.

Midnight:

1. Use a Brenner Head to shine a light on the Statue on the left side of the Courtyard, making it explode and reveal a Battery.
2. Pick up the Battery and place it in the Device next to the Statue.
3. Kill zombies using the S-Mine Trap to fully charge the Battery.
4. Pick up the Battery and place it in the left slot of the Machine in the Laboratory.
5. Interact with the Battery to start a defense. Defend it until it produces a Part.
6. While holding a Tesla Gun, place the Part on the Midnight Slot at the Tesla Gun Table in the Command Room to build it.

Reaper:

1. Have a Wustling run into the Metal Panel on the wall in the Sewers to reveal the Battery.
2. Pick up the Battery and place it in the Device near the door.
3. Kill 2 Bombers at the same time with the Saw Trap, twice, to fully charge the Battery.
4. Pick up the Battery and place it in the right slot of the Machine in the main Morgue room.
5. Interact with the Battery to start a defense. Defend it until it produces a Part.
6. While holding a Tesla Gun, place the Part on the Reaper Slot at the Tesla Gun Table in the Command Room to build it.

Return to the Morgue and Laboratory power switches and turn them back to green, then turn on a third power switch to the right of the Salt Mine doors.

Shoot the Coils that appear with a Tesla Gun to turn off the lights, then quickly use a Brenner Head to shine light on the two panels at the entrances of the Morgue and Laboratory. Rotate the numbers below each panel until every number shows a purple fingerprint. Once both panels are correct, they open and reveal a piece of a coin.

After picking up both coin pieces, place the coin in the wall in the Emperor's Chamber, then interact again to obtain the Red Talon Sword.

Go outside and watch the underside of the Zeppelin. When it attacks, four lights become visible beneath it. Concentrate fire on one. As the generator takes damage its light shifts from yellow toward red. Keep shooting until the generator breaks away and falls somewhere in the village. Watch its flight path so you can find it quickly.

Kill zombies close to the fallen generator. Their energy charges it. Once fully charged, it explodes and leaves behind a battery.

Pick up the battery and carry it to the Emperor's Chamber. The carrier moves more slowly and can't use a weapon while holding it, but it can be dropped and picked back up when needed. Place it into the Left Hand of God, on the right side when facing Barbarossa's statue.

Repeat this three times total. On the third cycle the Zeppelin may pull the falling generator back into the air. Damage the Zeppelin again to force another one to drop. Once all three batteries are inserted, interact with the Left Hand of God.

Equip the Brenner Head and aim down sights at each of the four paintings. Its purple light reveals a bird or eagle symbol and a Roman numeral. Record which numeral belongs to each symbol. The symbols and numbers change between matches.

1. Pub: upstairs, beside the Gramophone
2. Courtyard: inside the S-Mine trap area
3. Sewers: to the right of the door leading to Riverside
4. Morgue: inside the Spike Trap room

Return to the Voice of God machine in the Emperor's Chamber, directly in front of Barbarossa's statue. Set each of its four pillars to the Roman numeral matching the bird symbol marked on it. Once all four are correct, press the large red button. An energy field forms around the Hilt.

There are three Keepsakes: one of each colour per match. Shoot them down and collect them.

Yellow Keepsake: one of these locations:

• On a ledge above the Lebenblitz Machine in the Village Entrance
• On a windowsill between the Pub and Village Entrance
• On a roof above the Type-100 wallbuy in the Village Square
• On a windowsill above the Gas Valve in Riverside

Red Keepsake: one of these locations:

• On a windowsill above the Pub
• On a windowsill on the building next to the Pub
• On a roof in Riverside

Green Keepsake: one of these locations:

• On a windowsill above Klaus's Toyshop
• On a windowsill on the Clock Tower in the Village Square
• On a roof in the Courtyard

Place the Keepsakes in the window of Klaus's Toyshop.

Find the two Enigma Machines around the map with a Yellow or Red ribbon on them. The number shown on each represents which position to turn the matching Keepsake to, as if it were a clock.

1. Yellow Enigma Machine: one of these locations:
   • In a barrier in the Village Entrance
   • In the barrier near the Weather Vane in Riverside
   • In the barrier next to the Valve near Klaus's Toyshop
2. Red Enigma Machine: one of these locations:
   • In a barrier to the left of the Type-100 wallbuy in the Village Square
   • In a window looking through a window in the top of Klaus's Toyshop
   • In a barrier to the right of the Grease Gun wallbuy in the Command Room

Once the Yellow and Red Keepsakes are set, spin the Green Keepsake until a drawer beneath the Keepsakes opens. Pick up the Record inside.

Interact with a Weather Vane in Riverside. It points to one of three locations with a small yellow light. Shoot the light.

• Wall underneath the Bridge
• Window behind the Weather Vane
• Wall outside above the Courtyard

Shoot the Tesla Coils on the Water Wheel below the Weather Vane with a Tesla Gun to activate it.

Place the Record into the Gramophone in the Pub. This starts a sequence. Kill enough zombies near the Gramophone with the Red Talon Sword within a minute to make the song play in reverse. If you don't get enough kills, wait for the record to start again.

Once the record plays in reverse, listen for clicks or watch the green light on the side of the Gramophone. It flashes 4 numbers in a specific order. A short break between flashes marks the end of a number, and a red flash marks the end of the sequence. Remember the full sequence in order.

Input the numbers into the Voice of God in the Emperor's Chamber, left to right, then activate it.

Shoot the Chandelier above Barbarossa's statue with all 4 Upgraded Tesla Guns to obtain the Rabenherz.

Shoot the energy field surrounding the Hilt with the Tesla Gun. In co-op, every player must shoot the Hilt with a Tesla Gun at the same time.

Once the energy field disappears, interact with the Hilt to begin the boss fight.

Wait for a light to appear beneath the Zeppelin, then shoot it until a generator falls into the arena.

Kill zombies close to the fallen generator until it's fully charged and releases a battery.

Lure the Panzermörder close to the battery and shoot it repeatedly until it drops to one knee and becomes stunned.

While it's stunned, pick up the battery and interact with the boss to attach it. The boss then temporarily leaves the arena. Survive until it returns.

Repeat this process three times total. On the third phase the Zeppelin may pull a generator back into the air. Shoot it again to force another one to fall. After the third battery is attached, the Panzermörder is defeated and the ending sequence begins.
