Die Rise BO3 Custom: Easter Egg

High Maintenance, remastered

The main quest of Die Rise BO3 Custom is High Maintenance, the Easter egg of the Black Ops II map, with both sides: Maxis or Richtofen, who each want the tower of the dragon rooftop powered for themselves. Xela and Dobby’s Workshop page says both sides are “fully remastered and now possible with any number of players”: in Black Ops II it took four players, here it can be done solo. Steps that asked one player per symbol now ask as many symbols as there are players.

The steps below follow Kunjora’s complete map guide, released with the map on February 28, 2025, checked against Grave’s optimized solo guide of September 2025 and Sassy Asi’s Easter egg guide. Where only one guide gives a detail, the text says so.

Stage 1

The same for both sides: the NavCard table, the elevator symbols, the floor symbols and the two dragons.

Stage 2

The side you pick: Maxis in the Buddha room and with four Trample Steams, or Richtofen with the Sliquifier and the golden zombie crests.

Stage 3

The same for both sides again: the mahjong tiles and the tower, struck with the Galvaknuckles.

Before starting

The power

Turned on at the switch, low in the power building, as in Black Ops II.

A sniper rifle

For the dragons. The SVU-AS sold on a wall of the shopping area, in the spawn tower, does the job; Kunjora says no other kind of weapon works.

The Galvaknuckles

For the last step. Grave saves 6000 points by the end of round 4 to buy them down the elevator shaft of the broken tower.

A Trample Steam

Built two floors under the spawn room, for both sides.

Maxis

A Ballistic Knife from the Mystery Box, Pack-a-Punched.

Richtofen

The Sliquifier, built in the power building.

Step 1: the NavCard table

Its four parts lie on the dragon rooftop, at the top of the power building, and the table is built there, under the slope where the dragon sign stands, next to the tower.

The top of the table

On the floor just under the slope of the dragon sign, near the tower.

The radio

In the back corner behind the slope that leads down from the rooftop.

The fuse box

In the back corner of the drop-down section of the rooftop.

The fourth part

On the rooftop, just past the Claymore wall buy.

Saved for good

Since the update of March 12, 2025, the table is saved as soon as it is built: in later games it is already standing. Grave’s guide starts with it built “in a previous match”.

Step 2: the elevator symbols

Four elevators carry a symbol on their roof. Stand on the right one: it lights up and a sound plays. In solo, one symbol is enough, found by trial and error. In co-op, every player stands on a different symbol at the same time.

By the M14

The elevator next to the M14 wall buy, just outside the spawn room.

By the Bowie Knife

The elevator in front of the Bowie Knife wall buy, on the rooftop.

In the PDW-57 room

The elevator of the room of the PDW-57, the NavCard room.

By the Remington

The elevator near the Remington 870 MCS wall buy, on the ground floor of the power building. The update of March 3, 2025 fixed “gold elevator symbol near power switch not progressing the Main Easter Egg”.

Step 3: the floor symbols

Four symbols are drawn on the floor. Their places never change, but the order does. Step on as many as there are players, in the right order: a wrong one resets the sequence. In solo there is only one to find.

Rooftop

Next to the drop-down where the Semtex is sold.

M14 elevator

In front of the elevator next to the M14.

Restaurant

In the restaurant under the SVU-AS.

The jump to the power building

On the jump from the Buddha room to the power area.

Step 4: the dragons

On the rooftop, shoot the ball out of the mouth of each of the two dragon signs with a sniper rifle. Once both have fallen, pick a side: the next step decides it.

The dragon signs

The two dragons of the rooftop, each holding a ball in its mouth.

The lion statues

The balls end up in the paws of the two lion statues on either side of the spawn room door, where both sides use them.

Maxis side

In the lower floor of the upside-down Buddha room, get 15 kills close to the centre of the room. Kills outside that small area reset the count. A radio chime and a line from Maxis confirm it.
Pack-a-Punch a Ballistic Knife from the Mystery Box, go back to the lower floor of the Buddha room and fire it at the floor. Maxis speaks again. Grave advises storing it in the weapon locker afterwards, to take it out in later games.
Place a Trample Steam on each of the four golden crests of the floor, facing the way the crest points, towards the tower: in the spawn room next to the GobbleGum machine, at the foot of the elevator that leads up to the M14, in the drop-down section of the rooftop, and at the back of the rooftop next to two elevators. Once one is placed, the game lets you pick up another.
Take the two golden balls from the lion statues of the spawn room. Put the first on the Trample Steam next to the GobbleGum machine and the second on the one at the foot of the M14 elevator.
The balls bounce between the spawn tower and the rooftop, then explode by the tower, which lights up orange.

The Buddha room

The lower floor of the upside-down Buddha room, where the 15 kills and the Ballistic Knife shot take place.

The update of March 12, 2025 made the Trample Steams of this side impossible to destroy with explosives while they are in place.

Richtofen side

Shoot each golden ball held by the lion statues of the spawn room with 10 Sliquifier shots, until both spin. Kunjora and Grave both give ten shots.
Each player places a Trample Steam on one of the four golden zombie crests, facing the tower like the crest: at the foot of the slope that leads up to the tower, next to it on the other side of the slope, on the rooftop near the Semtex, and by the Quick Revive elevator near the M14. In solo, one crest is enough.
The Trample Steams must fire 16 times, flinging a player or zombies. The base of the tower then glows blue.

Grave calls this side the easier one, less dependent on luck. The update of March 12, 2025 fixed Trample Steams that stopped counting flings once they were placed again.

Step 5: the mahjong tiles

Eight mahjong tiles appear on eleven possible spots. Four show a direction, North, East, South and West, and four show a number from one to four; each is painted red, green, blue or black, and the colours change every game. A number and a direction of the same colour go together: the number gives the place of that direction in the order. In Kunjora’s game, one was black and West was black, so West came first.

1. The tower

On the corner of the railing of the tower, always a tile.

2. The spawn room

On the welcome desk of the spawn room.

3. The M14 elevator

At the foot of the elevator that leads up to the M14.

4. The SVU-AS room

On the broken staircase on the far side of the room of the SVU-AS.

5. The upside-down building

On a broken couch near the first Mystery Box spot.

6. Floor 25

In the broken elevator shaft that can be walked down.

7. The Buddha room

To the right of the teddy bear, on the upper floor of the upside-down Buddha room.

8. Under the power room

On the lowest level of the power building, near the Sliquifier workbench, around the corner from the GobbleGum machine.

9. The power room

On a table facing the Sliquifier workbench.

10. The rooftop drop-down

On a chair in the drop-down room of the rooftop, near the Mystery Box.

11. Past the MP5

In the corner of the room past the MP5 wall buy, near the boiler.

Three in blue

Three circles, painted blue.

Step 6: the tower

Write down the order, then melee the sides of the tower in that order with the Galvaknuckles; Grave says the Electric Bowie Knife works as well. A wrong order can be tried again the next round, according to Grave.

Striking the tower

Each side of the tower is struck in turn with the Galvaknuckles.

The tower stays lit

As in Black Ops II, the next game starts with the tower lit in the colour of the side already done, orange for Maxis and blue for Richtofen, and only the other side can be played.

Perma-Perkaholic

Every player gets every perk of the map, and, in Kunjora’s guide, all of them but Quick Revive stay after going down.

In later games

The NavCard table is already built. When the map came out, the Easter egg also unlocked the GobbleGum machines; the update of March 26, 2025 removed that lock.

A new ending

The update of March 12, 2025 added an end-game intermission of its own for each side.

A tally mark

The first of the five tally marks of the ranking system, added on August 16, 2025, is “Complete the Main Quest on any Victis map”.

Solo and co-op

In solo, the elevator symbols, the floor symbols and the Richtofen crests ask for only one each. In co-op, each player needs a symbol and a crest of their own, and the floor sequence grows with the number of players. The update of February 18, 2026 fixed the main Easter egg being “accidentally disabled”, and the one of March 2, 2026 fixed it “still being disabled”.
