Like all good Zombies maps, Firebase Z has a lengthy Easter Egg to complete that will unlock a secret cutscene, as well as a calling card to show off. Here’s how to complete it.
The Firebase Z Easter Egg went live on February 5 so everyone could begin on an even playing field. It didn’t take long for the most skilled hunters to solve it, but we’ve broken it down into easy-to-follow steps so you can solve it yourself. Buckle in though, it might take a while.
Before beginning the Easter Egg, you need to turn on the power, unlock the Pack-a-Punch machine, and get the RAI K-84 Wonder Weapon.
You don’t need to get the RAI K-84 before starting the Easter Egg, but it’ll be easier in the early rounds so we recommend getting it early by following our guide.
Here’s how to complete the Black Ops Cold War Firebase Z Easter Egg.
Step 1: Speak to Ravenov and Peck
Once the Pack-a-Punch machine is online, speak to Ravenov who will be marked with a waypoint. After talking to Ravenov, speak to Doctor Peck who’s located in the Mission Control Room where the leftmost Aether Reactor is.
Head back to the village and speak with Ravenov again, and he’ll give you a keycard. After picking it up, you’ll need to head to three lockers around the map.
Step 2: Open the lockers
The first locker can be found directly opposite Ravenov’s office beside the Quick Revive perk. Simply use the interact button to open it with the keycard, and take the Serum from inside.
The second locker is in the Colonel’s Office above the right-most Aether Reactor. Again, open it and take the Serum.
The third locker is found through the gate at the left of the Portal. Go into building directly in front, and you’ll find the locker on the bottom floor.
Step 3: Create Truth Serum
After taking the Serum from the final locker, head to the Field Hospital near the Barracks by the Heli-Pad. There will be a Chemical Mixer on the table. Interact with it to insert the Serums.
The Serums will begin to mix and you’ll need to fight off a hoard of Hellhounds while you wait. Once the dogs have been defeated, you can pick up the Chemical Mixer and take it to Mission Control Room above Peck’s Office.
Rather than going inside, you can find a vent to the right of the door. Interact with the vent and you’ll administer Truth Serum to Peck below.
Head down to his office, and after doing a little dance, Peck will tell you to head to the Data Center.
Step 4: Capture the Mimics
The Data Center is the building below the satellite dish, so head there and make for the Speed Cola Machine on the top level. On the left of the door beside the machine, there will be a computer with radar on the screen.
When you brush up against the computer, Peck will begin talking and you can unlock the machine. From the machine, you’ll be able to pick up four Essence Traps.
You’ll need to use these Essence Traps to capture Mimics.
Unfortunately, it needs to be specific Mimics. To find them, you’ll need to go around the map until you find a location with several Scorestreaks on the floor. One of the items will be a Mimic in disguise, and you won’t be able to interact with the rest.
Once the Mimic pops out, shoot it until it’s almost dead, throw the Essence Trap on the floor. As it walks over it double-tap interact and it’ll capture the Mimic.
Sometimes the Mimic will escape and if it does, you’ll need to get another Essence Trap from the computer and try again with another one.
Once the Mimic is captured, take the Trap back to the computer and listen for one of three characters to talk. We recommend turning on subtitles so you can see if it’s either:
If it’s not one of these characters, you’ve captured the wrong type of Mimic. Start the next round, then look for the items on the floor again and capture the Mimic that spawns there.
Once you’ve done this three times, a Floppy Disk will pop out of the computer that you need to pick up.
Step 5: Get Aetherium Crystals
After getting the Floppy Disk, take it to the Planning Offices which is the room above where we found the third Serum in Step 2. Insert the Floppy Disk and you’ll be asked to head to the OPC. This is the circular building outside Peck’s Office.
You’ll find the door is now open, and once you’ve looked at the Aetherium Portal, go and talk to Peck. After a lengthy conversation, you’ll be tasked with finding Aetherium Crystals.
Open the locker on the wall opposite Peck’s Office and you’ll be given an Aethermeter. With this, you need to collect three Aetherium Crystals.
You’ll also need the RAI K-84 and a shovel for this next step.
The shovel can be found in the Scorched Defence outside the building with Peck’s Office. Look in the leftmost hut at the top of the hill and it should be easy to find.
Aetherium Crystal 1 location
With the shovel in hand, head to the Jungle Defence area by the Juggernog Machine, at the right-most Aether Reactor. Go down the hill until you’re almost out of bounds and listen for a beeping noise coming from the ground.
When you’re in the right spot, you’ll get a prompt to dig and after doing so, a bubble will form around you. You’ll need to survive inside this bubble for quite a while, battling zombies, Manglers, and Hellhounds.
Once the bubble breaks, you can pick up the Aetherium Canister off the floor.
Aetherium Crystal 2 location
To find the second Aetherium Crystal, you’ll need to head back to the Planning Offices from Step 5. Listen for the beeping on the ground outside again, and dig up the canister once you’ve found it.
After digging it up, lots of Aetherium Canisters will pop up and you’ll need to find the one without black smoke. Almost all of the canisters will have black smoke swirling around inside, so you need to pick up the one with the white smoke. If you get it wrong, you’ll need to try again in the next round.
Just pick up the one with the white smoke and you’ll have the canister in your inventory.
Aetherium Crystal 3 location
You will need to have the RAI K-84 equipped to get the final Aetherium Crystal.
Head to the steps up to the Data Center which is right beside where you created the Truth Serum in Step 3.
After digging up the canister, it will teleport around the Barracks area, moving if you get too close. To pick it up, you’ll need to shoot it with the RAI K’s secondary fire mode. The button defaults to ‘Up’ on the D-Pad or ‘B’ on keyboard, so change the fire mode to the grenade and shoot the canister from a distance.
While the grenade you’ve fired is swirling above the canister, you can pick it up.
Step 6: Activate the portal
Well done for getting this far! We’re almost at the end.
You’ll now need to visit all three of the Aeitherium Reactors you turned on at the start of the game. Deposit a crystal in each, and then visit the OPC again and Peck will destroy the portal.
Go back to Peck and he’ll close the blinds to his office. The characters will all have a chat, and decide that the satellite can be used to reopen the portal. Head to the Planning Offices and interact with the computer by the window.
This will open up a mini-game where you need to click on the Satellite marked with a question mark. Some will have an American or Russian flag so only select the one with the question mark.
Head back to the OPC and you’ll now be ready to start the boss fight.
Step 7: Defeat Orda
After interacting with the control panel on the right-hand side of the OPC room, you’ll be teleported back to the starting village. Here, you’ll have to fight Orda, an Elder God.
Keep shooting him while being mindful of the zombies on the ground attacking you, and you shouldn’t have too much trouble taking him down.
Once he’s defeated, congratulations! You’ve finished the Black Ops Cold War Firebase Z Easter Egg.
This will show the final cutscene for Firebase Z, and you’ll also unlock a Calling Card to show off.

How to unlock the Scythe in Black Ops Cold War
The Scythe is a melee weapon coming to Black Ops Cold War. Here’s everything you need to know about unlocking the Scythe.
A brand-new melee weapon is coming to Black Ops Cold War and here’s everything you need to know about the Scythe, including how to unlock it.
It can be fun to rack up kills from a distance with an Assault Rifle after hopping into a game of Black Ops Cold War, and sometimes it’s more exciting to use a melee weapon to battle your enemies up close.
Treyarch accidentally released the Scythe melee weapon in Black Ops Cold War in a surprise update on June 6, giving players a sneak peek at the weapon. Now there is an official release date for the Scythe in Black Ops Cold War, so here’s how you can unlock it.
How to unlock the Scythe in Black Ops Cold War
The Scythe will be released for Call of Duty: Black Ops Cold War on August 12, 2022.
Here’s how to unlock the Scythe in both Multiplayer and Zombies:
- Multiplayer – Using a Melee weapon, get 2 kills while Ninja or Dead Silence are active in 15 different completed matches.
- Zombies – Using a primary Melee weapon, kill 200 enemies while Insta-Kill is active.
Completing 15 multiplayer matches will take some time, so you might be faster jumping into a game of Zombies.
The in-game description says that the Scythe is a “quick swinging” two-handed melee weapon that allows you to “reap a bountiful harvest by cutting down all who stand in your path.”

Best UGR loadout for Black Ops Cold War
The UGR is a brand-new SMG in Black Ops Cold War, so here’s our best compelte with Attachments, Perks, and Equipment.
The UGR is a brand-new SMG in Black Ops Cold War, and players can’t wait to try it out in multiplayer matches. Here’s our breakdown of the best UGR loadout to run in BOCW.
Even though CoD Vanguard is now in its third season, and Modern Warfare 2 is arriving this year, support for Black Ops Cold War is still going strong. After a huge Zombies patch on April 25, Treyarch have now added a remastered version of the Jungle map, as well as a new weapon.
The UGR SMG is an interesting close-range option, as it’s an “underwater rifle modified for improved land performance.” It doesn’t have the bullet velocity to take enemies out at distance, but it’s formidable in close-quarters combat.
If you’re looking to run it in multiplayer, you’ll need to know how to make the most of it. Check out our best UGR loadout for Black Ops Cold War.
- Best Cold War UGR loadout attachments
- Best Cold War UGR Perks & Equipment
- How to unlock UGR in Black Ops Cold War
- Best alternatives to Cold War’s UGR
Best Cold War UGR loadout attachments
- Barrel: 12.8″ VDV Reinforced
- Underbarrel: Spetsnaz Grip
- Magazine: Explosive Flechettes
- Handle: GRU Elastic Wrap
- Stock: KGB Skeletal Stock
We kick things off with the 12.8″ VDV Reinforced Barrel to seriously boost the UGR’s bullet velocity and damage range. The UGR is severely lacking in both departments, but this attachment makes it far more competitive in longer-range battles.
Next up, we went for the Spetsnaz Grip to keep the recoil in check and make it far easier to control. Then we chose KGB Skeletal Stock and GRU Elastic Wrap for a decrease in sprint-to-fire time and ADS speed, allowing you to get shots earlier while rushing around the map.
Many were surprised to see that the UGR comes with explosive rounds, so we couldn’t resist equipping Explosive Flechettes to our loadout. Aside from the obvious boost in overall damage, they also increase ammo capacity which is vital in a fast-firing weapon.
Best Cold War UGR Perk & Equipment
- Perk 1: Flak Jacket & Tactical Mask
- Perk 2: Scavenger & Assassin
- Perk 3: Ghost & Ninja
- Lethal Equipment: Semtex
- Tactical Equipment: Stimshot
We think the UGR is still effective with only five attachments, so we’re equipping Greed Wildcard to use extra Perks in each slot in BOCW multiplayer matches,
Flak Jacket and Tactical Mask are incredibly important in the first slot, as they’ll keep you protected from incoming explosives and Gas Mines, which can be frustrating when running and gunning.
Next, we picked Scavenger to make sure you never run out of ammo, as well as Assassin to keep the Scorestreaks rolling in. In the final slot, we recommend Ghost to stay invisible on enemy radars, as well as Ninja to help with flanking, which you’ll want to do a lot of with the UGR.
In terms of equipment, Semtex is an easy-to-use lethal, while Stimshot will give you a handy health boost when things get tough out there.
How to unlock UGR in Black Ops Cold War
To unlock the UGR SMG, players must kill an enemy revealed by their Spy Plane, UAV, or Field Mic with an SMG in 15 different completed matches. If you’re not a big multiplayer fan, it can be earned in Zombies by eliminating 1000 enemies while using an Epic rarity or better SMG.
You can also bypass the challenges altogether if you don’t mind spending 2,400 CoD Points on the new Lazar bundle.
Best alternatives to Cold War’s UGR
Black Ops Cold War has some powerful SMGs if the UGR isn’t working for you. The TEC-9 and LC10, in particular, remain incredibly strong in multiplayer matches and rank as two of the best weapons in the entire game.

How to unlock UGR SMG in Cold War & Warzone
Here’s everything you need to know about the new UGR SMG including how to unlock the weapon in Cold War and Warzone.
Treyarch continue to release new weapons for Cold War and the latest is the UGR SMG based on the APS underwater rifle that will be making its way to both Cold War and Warzone. Here’s how to unlock the UGR in Cold War and Warzone.
Although Vanguard is now in Season 3 and 2022’s Modern Warfare 2 has been announced, Treyarch are still releasing content for 2020’s Black Ops Cold War. Alongside a ton of Zombies changes that arrived with the April 25 update, Treyarch confirmed the classic Jungle map and a brand-new weapon would arrive in the “coming weeks.”
On May 6, the new UGR SMG made its way to the game alongside a remastered version of the Jungle map. Here’s how to unlock the UGR in Cold War and Warzone.
UGR SMG in Cold War & Warzone
Those who played Call of Duty: Ghosts may recognize Cold War’s new UGR SMG as it’s based on the APS underwater rifle that appeared in the campaign. The in-game description says it’s a “full-auto submachine gun” and an “underwater rifle modified for improved land performance.”
The weapon is projectile-based with quite a low bullet velocity, so you won’t be beaming enemies at range with ease. Players were also surprised to see that it comes with explosive bullets.
How to unlock UGR in Cold War & Warzone
Players can unlock the UGR by killing an enemy revealed by your Spy Plane, UAV, or Field Mic with an SMG in 15 different completed matches. You can also unlock the UGR in Zombies if you eliminate 1000 enemies while using an Epic rarity or better SMG.
The new UGR SMG has the same unlock challenge for both Cold War and Warzone, so it’ll be up to you to decide which game you’d like to complete it in. In addition, you can also receive the UGR straight away by purchasing the new Lazar bundle for 2,400 CoD Points.
