Call of Duty: Advanced Warfare Reckoning DLC brings a brand new exo-zombies map called Descent which concludes the exo-zombies saga.
Similar to earlier exo-zombies maps in the game, Descent also contains an extensive Easter Egg which can be completed to earn certain in-game rewards and Reunion Achievement or Trophy.
This guide contains step-by-step instructions on how to complete Descent Map Easter Egg in Call of Duty: Advanced Warfare Reckoning DLC:
Step #1 – Terminal Area
You need to head over to the Tidal Generator area having a long spiral staircase and shoot 3 bolts on the top of the walls until you see a blue light turned on. With all 3 blue lights turned on, you will open up an entrance to new Mark-25 Upgrade Station.
Step #2 – Underwater Goliath Switch
First off, you need to depressurize the door to the Floodable Air-Lock area. Afterwards, head over to The Trident Retreat’s The Landing Welcome Center and acquire an Exo-Goliath suit.
After acquiring the suit, head downward from the shaft that reads ‘Please Watch Your Step’ and make your way towards the Promenade.
After arriving at the Promenade, head up the stairway and drop down into the aquarium-like area. After dropping down, follow the path on the right-hand side to head towards the Lounge.
Once you again arrive at the Floodable Air-Lock area, open up the door and head inside to let the water rush in.
Head underwater and continue to follow the path lit by red lights. Interact with the button to turn on the blue lights which will open up a door to the Mark-25 Upgrade Station.
After opening up the door, retreat to surface and wait until Oz provides you with a Drone Challenge.
Step #3 – Drone Challenge
In order to complete the challenge, you need to destroy 5 drones flying around the map. The challenge can easily be completed by not going after zombies and focusing your attention on the drones.
It is highly recommended not to fail the challenge and using CEL-3 Cauterizer to complete it easily.
If you, somehow, fail to complete the challenge, you will have to start it again on the next round. You will know if you have successfully completed the challenge by a green-colored message appearing on the screen.
Step #4 – Charging Bomb Station
After completing the Drone Challenge, a Bomb Charging Station at the Concierge area – near the Galleria Entrance – will open up. The only way to power up the station is by electricity. The idea is to let an electric-charged zombie hit you while you are standing in front of the station.
Therefore, put down all zombies while standing in front of the station, but let the electric-charged zombies hit you.
However, do note that letting an electric-charged zombie hit you will deprive you off your exo-abilities for a while so make sure to run away after getting hit once and repeat the process.
Step #5 – Grenade Challenge
The only thing you need to know about the challenge is that you are not allowed to use your guns. For the sake of completing Grenade Challenge, it is better to buy Contact Grenades which come in really handy.
Step #6 – Jump Puzzle
The ‘Jump Puzzle’ requires you to head from one blue-lit platform to next using jumps and exo-boosts.
The challenge is a bit forgiving in the sense that even if you miss a jump or two, the blue-lit platform will respawn allowing you to try again until you succeed. However, make sure to keep an eye out on the zombies chasing after you.
Step #7 – Move Challenge
In the Move Challenge, you will lose money after each step so make sure to buy whatever you need before starting the challenge.
Another thing to note here is that you will be left with around 2,000 credits at the completion of the challenge so do not waste everything you have got before the completion of the Move Challenge.
Step #8 – Simon Says Game
Once you have completed the Move Challenge, you need to head over to the Reception Self Check-In and activate the lights on each screen in the following order – from left to right:
1, 3, 1, 2, 4, 2
Step #9 – Friendly Fire Challenge
The Friendly Fire Challenge basically produces clones of Lilith, Oz, Decker, and Kahn trying to shoot at you in addition to waves of zombies in the area.
Since you are unable to kill the clones, it is best to avoid them and continue killing the zombies to complete the challenge.
Step #10 – Number Board Puzzle
To start the Number Board Puzzle, you need to head over to the Tidal Generator area where you will come across a board with four numbers on it – top and bottom. All you need to do is to match the numbers on top and bottom of the board.
In order to change the numbers, you will have to complete certain in-game actions which will add ‘+1’ to the number on the bottom rows. For your convenience, here is what the number on the bottom rows mean:
- Row #1: exo-slam hits
- Row #2: jumps
- Row #3: equipment buys
- Row #4: kills
Step #11 – Rocket Challenge
The challenge is almost identical to Grenade Challenge, but you are provided with a Mahem MK-25 Rocket Launcher with infinite ammo.
Step #12 – Final Round
Once again, head over to the Tidal Generator area and go across the Upgrade Station to reach the Memory Tester Machine in order to access Oz’s memory.
Accessing the memory will transport you to another location where you will have to survive battle with the zombies without going down as there will be no reviving.
The final round is pretty tough and you will be provided with 3 AI teammates should you decide to go in solo. Once you complete the challenge, you will unlock Reunion Achievement/Trophy.
