Nightmare BO3 Custom:
Easter Egg

Step 1: the elevator and the padlock

1. Walk down the hallway of the starting floor and call the elevator. A lockdown of about two minutes starts.
2. When it ends, the window on the right breaks open. Climb through it into the break room, where the first dufflebag waits.
3. Use the blue control panel next to the window. It sounds an alarm, brings more zombies, and arrows and three letters appear on the walls: the first above the panel, the others out in the hallway, the last one at its far end. Nightmare Vision helps to see them.
4. Open the padlock of the locker at the back of the break room with the three letters, in the order they were found. If the alarm stops before the third letter, use the panel again.
5. Take the elevator key card from the locker and ride the elevator down to the sub ground floor, the reception.

The note

A note in the break room explains the puzzle: the combination of the padlock is written “in special ink on the walls”.

The padlock

Three dials of letters. The letters change from game to game: DDE for Fast Guides Glitch, FFB for Pankake101.

The elevator buttons

Eight buttons. Only SB, the sub ground floor, takes the players on with the quest.

Step 2: the code of the security room

The reception has one open door and several locked ones. The goal is the four-digit code of the security room, in the west wing offices.

1. Shoot the chains off the door of the west wing and survive the lockdown.
2. At the end of its hallway lies the flooded laundry room, where a crocodile swims. Cross it in Nightmare Vision, leave the vision at the back to read the note in the locker, and note its first two digits.
3. Back at the reception, find the fuse in one of the drawers of the desk in the office on the left.
4. In the maintenance room, under the reception, put the fuse in the first slot to open the east wing, and survive its lockdown.
5. At the end of the hallway of the east wing, a note on a bookshelf gives the last two digits.
6. Enter the four digits on the keypad of the security room door, in the west wing.

The reception

Where the elevator arrives, with T.E.D.D. behind the counter. Its doors lead to the west wing, the east wing, the maintenance room and, later, the upper floor.

The laundry room

Flooded, with the crocodile in the water. The first half of the code is on a note in a locker at the back.

The fuse

In one of the drawers of a desk, near the reception. The prompts ask to look at the drawers to open them.

The keypad

Next to the door of the security room. Each number is pressed with the use key, then the enter key.

The fuse box

In the maintenance room under the reception. Its four slots each open a different area; the single fuse moves from slot to slot.

Step 3: the four symbols

Four monitors around the building show a symbol, with a number below it that gives its place in the sequence. The security room turns the alarms off once the four symbols are entered in that order.

1. The first monitor is at the end of the west wing offices, across from the laundry room; the second in the staff canteen at the end of the east wing.
2. In the maintenance room, move the fuse to the third slot to open the east wing of the wards, on the upper floor, and find the third monitor in an operating room at the end of the hallway.
3. Move the fuse to the fourth slot to open the west wing of the wards, and find the fourth monitor in another operating room.
4. In the security room, set each of the four terminals to its symbol, then use the center console. The lockdowns stop and every wing opens for good.

A monitor

High in a corner, with its number below. The “EE tips” thread hears the static of the monitors before seeing them.

A monkey

The symbols change from game to game: Pankake101 gets a monkey on three of the four monitors and a radiation symbol on the third.

The terminals

Each terminal of the security room switches through the symbols until it shows the right one.

Fast Guides Glitch saves a lockdown: open the east ward with the third slot, run to its monitor, then move the fuse to the fourth slot at once and survive only the lockdown of the west ward.

Step 4: the vents and Yuri

1. Shoot open three vents: in the staff canteen at the end of the east wing, at the end of the west wing hallway on the ground floor, and in the room of bathtubs of the upper floor, called the hydrotherapy room by Fast Guides Glitch.
2. In the east wing of the wards, open the big silver door of the laboratory. A short scene plays, and Yuri appears.
3. Bullets do not hurt Yuri, and firing a weapon draws him to the player. Lure him to the far end of the building, then walk back without sprinting or shooting, and avoid his electric traps.
4. In the laboratory, take the remote control and the RC-XD, put the car down and drive it with the remote.
5. Follow the yellow arrows into the three vents and drive over the explosive parts in each. Electric traps knock the car out; it must then be repaired by hand, and a new remote taken from the laboratory.
6. Drive the rigged RC-XD up to Yuri and detonate it. Take the key card that drops from his body.

A dining room

Fast Guides Glitch shows this room of checkered tablecloths while it speaks of the staff canteen at the end of the east wing, which holds the first vent and the second monitor.

The RC-XD

The players drive the car through its camera. Until the three parts are collected, the prompt to detonate reads “parts missing”.

In the speedrun thread, ZeRoY wrote that a bug of the “RCXD/BOSS step” let the players take its target out without the three parts, and that it was fixed in the latest build; ZeRoY calls that target “Doc”. The change notes of version 1.01, on July 31, list an “RC-XD exploit fix”. That Doc is Yuri is a reading of these posts, not something a source states.

Step 6: the safe and the chapel

1. In the office on the right at the start of the east wing offices, on the ground floor, take the safe cracker from the drawers of a desk; Kunjora calls it the office of Dr. Gersh. Pankake101 takes it early, right after the first fuse.
2. Open the director’s office, at the top of the stairs of the reception, and shoot down the painting on the left wall. Use the safe cracker on the safe behind it and take the chapel key.
3. Open the chapel, at the end of the west wing of the wards, and use the Kronorium at its back. A long lockdown starts. Fast Guides Glitch runs around the pews on the right; the “EE tips” thread throws a Molotov cocktail at the entrance of the altar.
4. At the end of the lockdown, Blightfathers appear: one for Kunjora, two in the co-op game of Pankake101. Take the Kronorium and kill them.
5. Put the Kronorium in the bookcase of the director’s office. A secret passage opens.

The chapel

Lit by candles, with its pews and paintings. The Kronorium waits at the back.

The altar side

The same chapel on the Workshop page, with the crucifix and the rows of candles.

Step 7: the tunnel and the boss

1. Take the secret passage down to a flooded tunnel. The players cannot run in the water; zombies come from both sides. An Adrenaline Shot helps to move faster.
2. Use the doors at the end of the tunnel. A scene plays and the fight against the Nightmare begins, in a theater.
3. In the first phase, the boss throws theater seats: move from side to side and keep shooting. Zombies and spiders join in.
4. Past half of its health, it comes down to fight at close range and stomps those who come too close. Keep your distance.
5. Use the Adrenaline Shots and the ammo crates of the stage, and Nightmare Vision to get back on your feet.

A tunnel

A brick tunnel from the Workshop page. No guide read for this book says whether it is the tunnel of the boss.

Kunjora beats the boss in three to five minutes. When it falls, the final scene and the end credits play.
