Call of Duty Black Ops Cold War‘s newest Zombies map is now out. Yesterday afternoon, top YouTube and Twitch streamers raced to see who could be the first to discover and complete the Firebase Z Easter Egg. Although the new map launched on February 4, Treyarch did not unlock the Firebase Z Easter Egg until 1 PM EST/ 10 AM PST on February 5. From there, the hunt was on. Before the afternoon was finished, NoahJ456 and MrRoflWaffles were able to complete the Firebase Z Easter Egg.
The Firebase Z Easter Egg is not hard to complete but it does take some patience. During the Easter Egg, you will need the R.A.I. K-84. The easiest way to get this is by completing trials. You can also get the wonder weapon from the box. If luck is not on your side, you can build the R.A.I.K 84 as well. Below, we will be going over the steps it takes to complete the latest Zombies easter egg. Warning, cutscene spoilers are included!
Step 1 – Turn on the Power
At the start of the game, run over to Ravenov and talk with him by pressing Square or X. After you start the interaction, teleport over to Firebase Z. You can get to the teleporter either by unlocking the door or parkouring on the ledges. Once at the Firebase Z, you will need to turn on the power. To do so, you must go to the three Ethereum reactors and turn them on. Once there, you must protect it while killing zombies around the three generator nodes at each reactor. Once all three reactors are turned on, the power to the base is restored. Restoring power to the base also enables you to use the pack-a-punch machine in the starting area.
Step 2 – Peck’s Errand Boy & Grabbing the Serums
Once all three reactors are turned on, return to the starting area again and speak with Ravenov. After the conversation ends, you will get a message from Peck telling you that you need to return to the Military Compound to help with a job. Peck can be found in Mission Control behind the lower level shutters/glass window. Once you see Peck, hold square or X to talk to him. After the conversation, return to Ravenov in the spawn and talk to him once more. Once the conversation is complete, Ravenov will give you a keycard that you can pick up below his window.
With the keycard, you are now able to open three lockers around the map. The first locker can be found in the starting area right by Quick Revive in the room that has the stairs that lead to the teleporter. Hold Square or X to open the locker and collect the serum inside. The second locker can be found in the Colonel’s office located on the right side of the Firebase Z. Grab the serum and then head to the third locker located in Engineering.
Step 3 – Mixing the Serums & Getting the Essence Trap
Next, run over to the Field Hospital located behind the Barracks. In the Field Hospital use the vial mixer to fuse the three serums. While the vial mixer spins, Hellhounds will spawn so be prepared. Once all the Hell Hounds are dead, grab the mixer and bring it to the air conditioner located outside of the OPC by the giant globe. Placing the agent delivery system on the air conditioner will pump truth serum into Peck’s lab. Head down to Peck’s lab to see him dance.
Once he’s done with the quick jig, Peck will tell you to go to the big satellite dish. As you are running, run across the left-hand side until you reach the tall green computer in the Data Center. Hold the square / X button to interact with the computer and receive the essence trap. The essence trap takes the support grenade slot so be prepared.
Step 4- Collecting Mimics
Now that we have gotten the essence trap, we will need to collect mimics with them. To do so, you will need to lower their health and suck them up with the essence trap. If you’re confused, throw it down on the ground and have the mimic get close to it. Once it is near the trap, double tab the Square/X button to activate it. Capture is not guaranteed, mimics do have the chance to break out. If they do break out you will need to go back to the computer and pick up another essence trap. There are special mimics that need to be collected. If multiple items are on the ground and unable to be picked up, one will spawn into a mimic.
Capture that mimic and bring the essence trap back to the computer. Interact with the side of the machine while avoiding the pickup area for the essence trap. The computer will then process the memories of the mimic. If you have captured the wrong mimic, the computer will either say memory corrupted or a random voice will talk. The three characters you want to gain memories from are Sokolov, Brahms, and Zabim. Look for mimics at Pecks room in the village, in front of the weapons lab by the motor vehicle pool, or the planning offices by the reactors. If no mimics spawn, progress the round when ready. Each of the three character’s memories will give you a code that Weaver will remember.
Step 5 – Open the Portal and Gather Ethereum Crystals.
Once you have all three codes, a floppy disk will come out of the computer. Pick up the floppy disk and take it over to the planning office’s green computer. Enter the floppy disk into the computer. You will then be instructed to head over to the OPC or the Omega Portal Chamber. The Omega Portal chamber is the giant globe by the OPC room. The computer will then unlock the Portal chamber and a portal will open. Once you see the portal open, return to Peck and talk to him. Peck will then tell you that you need to gather Ethereum Crystals.
Once the conversation is over, head to the left of Peck’s room to the locker outside. Use said code to open the locker. The locker will give you a new device called the Ethereum Canisters Detector. With this detector, you will need to find the crystals around the map. Before doing that though, you’ll need a shovel. Head over to the Scorched Defense bunkers. Inside will be the shovel you’re looking for.
- The Lockdown Canister can be found at the Jungle defense zone. Down at the very bottom of the zone look for a pile of dirt. As you get closer to the canister the detector will start to beep faster. Once the beep is rapid, dig up the canister. After digging it up, a lockdown phase will begin. Defend yourself from Manglers, Mimics, dogs, and zombies until the lockdown is complete. Once the lockdown bubble is gone, pick up the canister.
- The Smoke canister dig spot can be found in the Open Lot by the window. Once you dig it up, multiple canisters will spawn in the open lot. You will need to find the canister that does not have any black smoke inside it. Canisters will spawn in the Open Lot, Engineering, The Planning Office, and the outside. If you pick up the wrong one, Mimics will spawn and you will have to progress to the next round. The correct canister will have only white smoke and particles around the crystal.
- The teleporting canister requires one player to have the R.A.I.K – 84. This canister is located on the outside of the right side of the Field Hospital. You will see the stairs leading to the Data Center on your right. This canister will teleport around the Barracks Lot. Do not attempt to run to the canister to pick it up. Instead, you will need to use the R.A.I.K- 84 grenade launcher to shoot it; to switch to the grenade launcher, hit up on the D-Pad. Once you have shot the canister, run over to it and pick it up.
Deposit the Crystals
Once you have all three Ethereum canisters, you will need to take a canister to each reactor. Interact with the reactor to deposit the Etherum crystals. Depositing all three crystals will overload the power in the facility. Once you have deposited the third crystal, you will need to return to the OPC. Once at the OPC, you will see that Dr. Peck has manipulated you. Run back down to Dr. Peck’s area. Peck’s shutter will be closed and Weaver will start talking to your character. Once Weaver is done talking, you will need to head back to the Planning Offices.
Once in the Planning offices, the computer by the window closest to Helipad will turn on. Interact with the computer to trigger a mini-game. The mini-game will have you move around a blue dot to align the satellite. Hover over the yellow dots to see each area. You will need to select the “?” mark yellow dot to correctly align the satellite. Once you have correctly confirmed the correct location, the satellites in the area will realign. A giant beam will come down from the sky hitting the satellites and go throughout Firebase Z.
Once the Satellite is aligned, head back to the Omega Portal Chamber and go to the right terminal computer. Interact with the computer to start the boss fight.
Once you interact with the computer in the OPC, a cutscene will start. A well-known character (Samantha Maxis) will step out of the portal wearing important gear of the original Zombies’ crew. Your characters will then run to the teleporter as things start to get hectic. Once you return to spawn, the boss fight will start.
The boss fight is against an Elder God called Orda. The Orda is primarily weak to Tomahawks but the R.A.I.K 84 is a good secondary form of damage. The easiest way to damage the Orda is by hitting the exposed lava pools on its body. Shooting the lava pool will do increased damage to The Orda. Ranged weapons will help you to stay safe while hitting the boss.
While you are fighting the boss, Manglers, Mimics, Zombies, and dogs will spawn. Make sure to clear smaller enemies to stay safe. If you do go down or need an extra punch, the WonderFizz and Pack-A-Punch Machine is in spawn. You also have the ability to grab new armor in the room next to the Wonderfizz.
The Orda Boss has a variety of attacks. A slam that throws down its big club hand will instantly down you if hit. It can also shoot out a plague cloud that can be shot out of the air. If hit, they will burn the player’s health. The final attack has The Orda shooting flaming Hell hounds out of its hand at you.
With that, congratulations! You have completed the Call of Duty: Black Ops Cold War Firebase Z easter egg!
