Mahjong in Die Rise. Four colors: red, black, blue, green. Four directions: north, south, east, west. Various shapes. The Zombie mode in Black Ops 2 continues to reveal its secrets. The “Maintenance” guide is available here.

The ultimate Survivor Guide is available here. This guide helps you uncover all the secrets of the Zombie mode in Black Ops 2. With its new DLC: Revolution and the new map Die Rise, the Zombie mode returns once again. Surprisingly, Black Ops intertwines with Mahjong.
You may wonder, what does Mahjong have to do in Black Ops 2? The answer lies in the fact that the puzzle pieces of Die Rise are numerous and come in various forms, including those of the famous yet obscure Chinese game. Throughout the Die Rise map, you will find different pieces (or tiles) of Mahjong.

The Mahjong tiles come in several colors, specifically, there are a total of four colors for these tiles:
– Blue
– Green
– Red
– Black

Additionally, certain tiles indicate directions, which correspond to the four cardinal directions that everyone is familiar with:
– North
– South
– East
– West
Based on the colors and the indicated directions, you’ll need to head to the radio tower equipped with your Galvaknuckles (taser fists). Methodically strike the tower at its four corners in a specific order (an order dictated by the combination of colors, the number on the tile, and the associated direction) to make it work.

Keep in mind that the Mahjong pieces you discover will vary from match to match, making it crucial to know the representations and values of each tile. You will only need six tiles to achieve your objectives; the rest are extraneous.
These Mahjong tiles can be found easily. Thus, this guide helps identify the most important ones, which have fixed locations, while others may appear randomly across the map. Here’s a list with precise locations for these tiles.

Near the radio tower

Right by the Spawn, on the table in front of the two lion statues

On the sofa on the lower levels

In the kitchen, clearly visible

On the shelves in the AK74u room

In the elevator shaft, on the floor at the lowest level of the map
Once all the Mahjong tiles are discovered, you’ll just need to activate the Tower to earn the achievement or trophy “Maintenance“. If you’ve succeeded, you’re undoubtedly a seasoned Zombie mode enthusiast.
