High Maintenance

High Maintenance is a zombie easter egg in Call of Duty: Black Ops II, for Die Rise. This easter egg requires the player to "be the architect of their instruction". High Maintenance features branching Easter Egg storylines (Ludvig Maxis and Edward Richtofen) just like Green Run; the players also need to activate another polarization device like the one in Green Run.
As with the Tower of Babble Easter Egg, this Easter Egg must be completed on original difficulty, as easy difficulty will render all Easter Eggs throughout the map invalid and will not work accordingly. High Maintenance also requires four players for both Maxis' and Richtofen's path of the Easter Egg.
Completing one side of this Easter Egg will carry over into subsequent playthroughs, however the player will still be able to complete the other side freely so long as none of the other players that started the game have completed that side of the Easter Egg beforehand. Completing the other side of the Easter Egg will unlock the originally completed side for future playthroughs, however it will also lock the more recently completed side. In other words, one side of the Easter Egg may not be completed twice in a row. To switch which side of the Easter Egg is saved to the player's profile (by completing the opposite side Easter Egg), they need to host or be in the game from the lobby; they cannot join a game in progress. For example, if a player has the Richtofen side completed, and joins a game in progress in which they complete the Maxis side, the Richtofen completion will still be saved regardless of the Maxis completion, because they weren't in that game from the beginning. However, activating the endgame on Buried will reset all Easter Egg progress across that map, Die Rise, and TranZit, allowing the player to do either side as both will be unlocked as neither side will be considered to have been completed. Alternatively, to simply repeat the Easter Egg side that is currently saved to the profile, the player may join a game in progress so long as none of the players who started the game have the desired side locked as the game does not lock the Easter Egg after the game has begun.
The canon ending is confirmed to be Maxis' side of the quest in the official Zombies Timelinehttps://www.callofduty.com/zombieschronicles. 
==Walkthrough==
===Step 1 ===
Simply turn on the power to begin. Note that building the NAV table is required to start the Easter Egg or standing on the symbols may not work during the Easter Egg, and is required for the final ending Easter Egg which is on Buried.
Note: This Easter Egg tends to be very glitchy, be prepared to encounter them and be unable to progress.
===Step 2 ===
All four players must step on the four golden rings on top of four elevators. One spot is on the elevator that leads to the Bowie Knife and is accessible from the power room. Another spot is on the elevator near the Remington 870 MCS and the MP5. The other spots are on top of the Quick Revive elevator and the other elevator next to Quick Revive, both elevators are adjacent to where the player builds the Trample Steam. All four players must step on them simultaneously. Care should be taken that the elevators kill the player if standing on them while they are near the top floor by crushing the player. Once done, Richtofen and Maxis will speak to the player. 
===Step 3===
Match the gold symbols on the floor. There is one by the M14, one above the AK74u, one on the roof to the left of the Semtex Grenades, and the last is past the SVU-AS by the cafeteria. They are the same symbols as the elevator symbols. They must be lit up by stepping on them in sequential order. This order changes per game, so it is mostly guessing and trying different combinations. Once all four are lit up, Richtofen and Maxis will speak to the player.
===Step 4===
Acquire any sniper rifle and look into the dragons' mouths. There should be a small ball in each mouth. If the player shoots both balls out of both dragons' mouths, they should teleport under the lions' paws in the starting room, adjacent to the Olympia.
This is the point where the player must choose a side.

===Step 5===
The player who has acquired the Sliquifier needs to continuously shoot the balls until they begin to spin. This will take 20 direct shots on each ball, so it would be wise to save the Sliquifier's ammo prior to this occasion. Once both balls are spinning, Richtofen should tell the player to make a "blood sacrifice". Maxis is now locked in the systems, allowing Richtofen to proceed.
===Step 6===
Scattered throughout the map are golden zombie symbols with circles outlining them around the map, one near the spawn by the M14, two near the Claymores on the roof with the NAV table next to the pathway that leads down to the floor below, and one near the Semtex on the same building. Each player will need to place a Trample Steam on the symbols so that they face the radio tower on the roof. Once all four have been placed down, allow zombies to be killed by the Trample Steams. It is advised that the player does not clear the couch debris blocking the escalator near the M14 so that zombies can only come from one way and the other way blocked by the Trample Steam. Richtofen will indicate that the step is completed by asking Samuel to use the Galvaknuckles. However, any player can use them. Each zombie symbol will give a quote from Richtofen if the Trample Steams are placed correctly; the player needs to make sure that they have heard all four or they will not be able to move on.
Note: Simply activating the Trample Steams works for this step, whether that is by having players fling from them or by having zombies get flung.

===Picking up the Balls===
After the balls have been shot from the Dragons' mouths and moved to the lion statues in spawn, they will give a prompt to " Hold [interaction button] to pick up ball" once near them. The balls can be picked up at any point as long as they have not been shot with the Sliquifier until they spin. When the balls are picked up, there will be no indication that the player has them or not. In order to identify whether a player has a ball, make them walk into both lion's paws. If the player gets a prompt to "Hold [interaction button] to place ball", that means they have a ball.
Note: A player can only hold one ball at a time.
===Step 5===
Kill zombies on the ground floor of the Buddha room, Ludvig Maxis will say: "Reincarnation will reveal the way forward" when the players have killed a satisfactory amount of zombies. The step requires 15 zombies to be continuously killed inside the Buddha room, meaning that any kills that occur outside the Buddha room during this step will reset the progress and the player will have to start over again for the 15 kills.
===Step 6 ===
A player must then acquire the Ballistic Knife from the Mystery Box and Pack-a-Punch it into The Krauss Refibrillator or have acquired The Krauss Refibrillator beforehand. After the player has Pack-a-Punched it they should hear a quote from Maxis. If they do not, it most likely means the player holding The Krauss Refibrillator does not match the requirements. Check IMPORTANT below for the requirements. The player must then take The Krauss Refibrillator into the Buddha room and fire it. Provided all steps have been done correctly and the requirements are still matched, a quote from Maxis will play.
IMPORTANT: This step only works if the player holding The Krauss Refibrillator: has not bought either the Galvaknuckles or the Bowie Knife, and also has not bled out.
===Step 7===
The players must now each place a Trample Steam on each of four lion symbols on the ground, facing in the directions of the lions within the symbols. The lion symbols are located as follows:
* In the spawn room, near the foot of the left staircase
* In the first room after the spawn room, at the bottom of the escalator that's near Quick Revive
* On the rooftop with the dragons, next to the two elevators which are right beside each other on a corner that descend into the power room
* On the rooftop with the dragons, near the elevator on its own in the east corner, accessible by running up the ramp towards the spawn building, turning right, and dropping down
Grab the balls from the lion statues. The players must then place the balls on top of the Trample Steam; each ball will bounce from one Trample Steam to another that are across from each other. Once both balls are being flung around, an orange surge will go through the radio tower. After this is done, a player must now obtain the Galvaknuckles.
IMPORTANT: Picking up another player's Trample Steam can make the players holding the balls not get the prompt to place the ball on the Trample Steams. If a Trample Steam does not give the prompt to place the ball on it, destroy all Trample Steams.
Note: Sometimes a ball might move back to under the lion's paw. If that happens, have a player pick it up and place it down on a Trample Steam that does not have a ball already being flung from it.

===The Mahjong Tiles===
There are Mahjong tiles of different colors located throughout the map. These tiles indicate the order in which the player should melee the radio tower with the Galvaknuckles (see the final step). There are eight tiles, but there are eleven locations for the tiles to spawn. The order changes from game to game so it will not be the same each game.
Four of the tiles have Chinese Mahjong symbols, which indicate a compass ordinal. The other four tiles are color coded with the directional tiles and they indicate the order in which that particular post should be hit. Each compass point and bamboo tile is colored, and same-colored ones are correlated. The colors are red, blue, green, and black. For example, if the player finds a green "north" and green three bamboos, the north side of the tower is hit third. This order changes every match.
Note: The numbered tile for 1 is a bird instead of a bamboo and is commonly mistaken for a directional tile.
Note: These tiles can be found at any point in the game as the order does not change at any point.
The potential location of these tiles is as follows:
*One corner of the tower will have the North directional tile that also corresponds with that corner.
*In the spawn room on the same desk the compressor for the Trample Steam sometimes spawns on.
*At the bottom of the escalator near the M14.
*On the broken stairs that lead to the SVU-AS from the spawn.
*On the couch with four circular cushions near the initial Mystery Box spawn.
*On the last level of the elevator shaft that the player can stand on above the AN-94.
*The Buddha room (after the AN-94 room) on the top level at the back of the room to the right.
*On a shelf, near the Sliquifier next to a soda can and a basket.
*On a table with a sewing machine in the power room.
*On a lawn chair near the Mystery Box spawn on the roof.
*In the kitchen near the MP5.

===Final Step (for both sides)===
Once the order is determined, the player must melee the bars with the Galvaknuckles in that order. North faces the Trample Steam room and has a tile on its corner and West faces the sun. Figuring out South and East are just opposites. Once the correct order is inputted, the radio tower will have a surge of electricity hit it and light up in the taken side's respective color (blue for Richtofen or orange for Maxis), with all of the dragon's flares sparking, and the High Maintenance achievement will be unlocked.
Alternatively, trial and error can be used due to the order not changing. However, this is not recommended as this step can only be attempted once per round. Should the player melee the poles in the wrong order, the tower will cease to glow until the round ends.
Note: This step has a possibility of glitching, making it so that when the tower is punched even in the correct order, the step will not complete, and the tower will stop glowing but will light up next round. 
* One way to bypass this glitch is to have the player(s): deactivate the tower’s corners, progress onto a new round to reactivate the tower, punch each corner once in any order while avoiding the corner in the 1st position, then input the order obtained from the Mahjong tiles even if the tower stops glowing.
This is then the completion of the High Maintenance Easter Egg.
==Reward==
Once the players have completed either side of the Easter Egg, each player will receive all six available perks in Die Rise; this does not include PhD Flopper as the perk is not in the map, only the machine as its own miniature Easter Egg or "troll" on the part of Treyarch. Unlike previous maps which awarded players with every available perk upon completion of the Easter Egg, they can be lost if the player is downed.

*Richtofen's version of the "High Maintenance" Easter Egg.
==Trivia==
*If the player completes Maxis' path, the pylon will be lit orange and the "Die Rise" icon will flash with orange lightning on the world map.
*If the player completes Richtofen's path, the pylon will be lit blue and the "Die Rise" icon will flash with blue lightning on the world map.
*If different players that did different sides of High Maintenance play in the same lobby, the pylon will be lit both blue for Richtofen and orange for Maxis.
