High Maintenance

High Maintenance is a zombie-related gameplay achievement/trophy in Call of Duty: Black Ops II, for Die Rise. This achievement/trophy requires the player to "be the architect of their instruction".

This easter egg must be completed on the Original difficulty setting if you started the game in a 'Custom Games' lobby.

Step 1
Note that the Navcard from TranZit is required to complete the first step.

You must build the NAV Table in order to complete the first step, the NAV table consists of the meteorite, the radio, the table and NAV card reader.

Step 2
Now that you have built the navcard table, you must step on the four golden rings on top of the elevators. Once done, Richtofen and Maxis will speak to you.

Step 3
Match the gold symbols on the floor. Two in the spawn area, one on the very top, another on the bottom, past the SVU by standing on them. The other two are located in the radio tower area. They are the same symbol as the elevator symbols. Then one person gets on the symbol and the other people follow, but not at the same time. Richtofen and Maxis will speak to you.

Step 4
Acquire the SVU-AS and from the spawn room look into the dragon's mouths. There should be a small ball in each mouth and snipe it out. Look behind you and if you hit both balls out of both dragons mouths they should be under the lions paws.

Step 5
Shoot each ball with the Sliquifer and once complete Richtofen should tell you to make a "blood sacrifice".

Step 5
Remove both of the balls from under the lion's paws.

Step 6
Kill zombies in the tilted room (the Buddha room with red color), Maxis will prompt you saying 'Enough! Enough!' when you have killed enough.
