One player is enough to complete the map. Requirements for completing the map:

• Collect the plane and fly to the Bridge three times
  
• Have the Hell's Retriever and the Spoon
  
• Obtain the Blundergat by collecting skulls
  
• If the conditions are successfully met, the Counter in the Catacombs will cycle through numbers.

This guide is also relevant for Black Ops 2, with the following exceptions:

• No Gobblegum
  
• It is not possible to complete the map solo.
  
• No Magmagat
  
• No "Stamin Up" perk
  
• No "Hide and Seek"
  
• When the Washing Machine is activated on the 1st round, the Warden will not be in the Remaster

Mob of the Dead remaster allows you to use Gobblegum. Recommended for completing maps and simplifying difficult moments:

1. "Idle Eyes" - will not only allow you to avoid fatal accidents, but also make it a little easier to obtain a Magmagat.
2. "Immolation Liquidation" - Although you can get a Blundergat for free, it is unlikely that you or your friend will refuse to receive a second one.
3. "On the house/Soda fountain/Perkaholic" - The Gobblegum "On the house" will be the most useful for a cooperative game, as it allows the whole team to get a free perk.
4. "Extra Credit/Shopping Free" - there are many doors on the map, especially in the docks and catacombs, buying perks is also not cheap, "Extra Credit" or "Shopping Free" will help, but since perks and some doors can only be activated in the "Afterlife" mode, "Extra Credit" is best suited.
Choose the last 2 Gobblegums according to your taste.

To collect materials, you need the Warden's Key. It can be found in one of two locations:

• In front of the Cafeteria entrance
  
• At the entrance to the Warden's Office.
  

• You can retrieve the Warden's Key by electrocuting the panel in the "Afterlife" mode.
  

• Before entering the Shower and Laundry, it is necessary to open the door with an electric shock. To do this, we interact with the nearest electrical panel
  
• In the "Afterlife" mode, we enter a hidden passage, turn around, look up and electrocute the shield.
  
• Open the door to the Laundry room with a Key, power another shield next to the washing machine.
  
• Interacting with the washing machine will cause a horde. Wait until the laundry is washed.
  

The rigging are lying on the elevator in the Catacombs.
To lower the elevator, open the Counter with the Warden's Key, then enter the "Afterlife" mode using the switchboard near the elevator
Enter the numbers in the Counter in the order they appear (in each game session, the order is random)
The elevator will descend and you can pick up the rigging, you are given 1 minute to open the elevator.

The engines are behind a closed door in the Warden's office, powered by electric barrier.
To turn off the current, you need to turn off 3 panels in the Generator Room at the docks, using the "Afterlife" mode.
2 panels will be in one room
The last one will be in a hidden passage in the same room.
When 3 panels are turned off, generator in the corner of the room will light up and the barrier in the Warden's Office will turn off.

The tank are in the docks, the entrance to them is locked and the door can be opened with electric shock. The easiest way to open the doors is not to touch the lock, but to enter the "Afterlife" mode and shock the panel with an electric shock, then open the door with the Key. Otherwise, you will have to spend up to 2 charges of "Afterlife".
An important tip is that the step of turning off 3 panels in the Generator Room can also be done during the step with the Tank, the main thing is to open the door leading to the room, so you will save up to 2 digits of "Afterlife", in a cooperative game, the 2nd player can resurrect the player in "Afterlife", but not to the end which will allow him to stay in the "Afterlife" much longer.

Lock in the Infirmary.

In the Infirmary near the Hellhound, activate the electrical panel and in the "Afterlife" mode find a hidden passage to the roof, climb up and shock the panel.
NOTE - after the players get back to Prison, all the assembled parts will be replaced with canisters at the places where the aircraft parts are picked up. The flight to the Bridge must be repeated at least 2 more times to complete the map

To obtain this Wonder weapon, you must feed three hellhounds.

• The first hound will be near the starting location, in the lava room.
  
• The second hound is in the Infirmary, near the Deadshot Daiquiri perk
  
• The third hound is in the docks, next to the craft table
  

After feeding the hounds, you can pick up the Hell's Retriever in the Catacombs.

The Hell's Redeemer is optional for completing the map. You need to have the usual Hell's Retriever kills (15-20)
On the Bridge, you need survive 1 round (for sure, survive 2), using only the Hell's Retriever. If successful, there will be a sound of execution.
Return to the Prison and throw the Hell's Retriever into the lava near the starting location (the Tomahawk should not return to us)
Wait for 1 round and you can pick up the Hell's Redeemer in the Afterlife mode, where you picked up the Hell's Retriever before.

After obtaining the Hell's Retriever, collect 5 blue skulls by throwing the Tomahawk to obtain a free Blundergat. You can collect them in any order.

• In the cell near the Starting Location
  
  
• In the Warden's Office, behind a barricade on a lamppost
  
  
• In the docks, on a wooden post
  
  
• Behind the Jugger-Nog perk, on the lantern stob
  
  
  
• On the roof behind the plane, at the edge on the left side.
  
  
• Take the Blundergat in the Warden's Office.
  
  

Obtaining a Magmagat is not necessary to complete the map. You can get a Magmagat only after arriving at the Bridge at least once. It is recommended to take the "Idle Eyes" Gobblegum before.

• In the Warden's Office, press the default F button on the fireplace (there will be no interaction button on the screen), after which the boards will burn and it will be possible to temper the Blundergat
  
  
  
• Kill zombies in the zone until 3 skulls turn blue, you can pick up a Tempered Blundergat (before taking the Blundergat, use the "Idle Eyes" Gobblegum to make the way easier)
  
  
• We need to take the Tempered Blundergat to the Forge in the Generator Room at the docks. The Blundergat will cool down over time, because barrels with blue flames will meet along the way, bring the Blundergat to them and this will prolong the time before it cools down.
  
• The path passes through the Catacombs, immediately after leaving the Warden's Office towards the "Double Tap Root Beer" Perk
  
  IMPORTANT NOTE: DO NOT CHANGE WEAPONS OR USE GUM, THIS WILL REMOVE THE TEMPER. IN CASE OF FAILURE, THE BLUNDERGAT MUST BE TEMPERED AGAIN
  
• There will be a Forge in the Generator Room, interact with it to power it, then forge the Blundergat into a Magmagat.
  
  

Getting Acid Gat is not necessary to complete the map. A variation of Blundergat that shoots explosive shells filled with acid and attracts zombies.
To make a Converter to Acid Gat, it is necessary to collect materials.
1. The coil. He lies in the Warden's Office in one of three places

• Under the door
  
• Near the fireplace
  
• To the left of the Mysterious Box
  

2. The suitcase. It lies in one of the three corridors.

• Near the starting location
  
• Under the stairs in the hallway to the Warden's Office
  
• Next to the electrical panel near the shower.
  

3. A vessel with acid. It is always in the Infirmary.

• On a table near a hidden passage
  
• In the corner of one of the rooms
  
• Near the bath
  

Create a Converter in one of the Craft Tables

You can get a Spoon after flying to the Bridge at least 1 time.
Use a Hell's Retriever to remove a poster in one of the cells near the Warden's Office.
Enter the "Afterlife" mode and move the Spoon in a hidden passage with an electric shock.
In the Cafeteria, there will be a Spoon on the table behind the barricade, pick it up with a Tomahawk throw.

Getting a Golden Spork is not necessary to complete the map. It is necessary to obtain an Acid Gat and a Spoon
We lower a Spoon into the blood bath in the Infirmary with the F button by default (the interaction button is not visible)
Take Acid Gat and go down to the Shower, kill zombies only with of Acid Gat in the Shower until you hear laugh.
Go back up to the blood bath and press the default F button (the interaction button is not visible), to take the Golden Spork

This step will only be available after completing all the previous steps. Make sure to fly to the bridge three times.
In the Catacombs, the Counter will start counting numbers. Enter the "Afterlife" mode and enter the prisoner numbers in any order:
101 - 481 - 386 - 872
The Warden's voice will indicate that everything is done correctly, and the screen will turn black and white. Audio recordings will appear from the Catacombs to the Roof, and you must listen to them all.
Laugh means that all Audio Recordings have been listened to. All players must enter the "Afterlife" mode and board the plane using the default F button (the interaction button is not visible)

• The shield grid is located in the Catacombs or in the corridor to the Generator
  
  
• The shield clip is located in the generator room
  
  
• Last piece in Dock
  
  
  Zombie Shield
  
  

To obtain the perk, you must have a Magmagat.
The perk is located in a secret room behind a door in the Infirmary, opposite the hidden passage to the roof. The door can be opened by shooting a wooden board with a Magmagat

Samantha doll can only be found after entering the numbers 115 on the Counter in the Catacombs.
After entering the numbers, the Warden will speak.
The doll lies in a Hidden passage that activates the Shower Room.
We jump onto the first platform and there will be a doll lying on the bottom left, electrocute it.
The doll will move under the acid trap in the Cafeteria. To start the game with the doll, interact with it with the default F button (the interaction button is not visible)
In total, you need to find and shoot 6 dolls, the music serves as a clue to them, the closer the clearer. Places where the doll appears:

• On burning tables facing the Cafeteria exit
  
• On a pipe in front of the Cafeteria entrance
  
• Behind the barricade on the table
  
• Behind the closed grate on the right immediately after entering the Cafeteria
  
• Over the barricade
  
  After the 5th doll, the last one will be under the acid trap.
  

As a reward, you will receive a Maximum Ammo bonus and the song Where Are We Going (2018) from Blood of The Dead.

Activate 3 bottles of whiskey in any order to play the song "Rusty cage".

• The first bottle is on the shelves to the right of Olympia
  
• The second bottle in the Infirmary
  
• Third in the docks, behind the crate
  

• The song "Where are we going" is activated in the Catacombs on the Counter. Enter the "Afterlife" mode and enter the numbers 935
