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:

  • Sokolov
  • Brahms
  • Zabim

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.

Firebase Z in-game

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.

RAI K-84 bocw zombies firebase z

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.

Top 5 tips to dominate Apocalypse in Black Ops Cold War

Black Ops Cold War Season 2 has added Apocalypse to its ever-growing arsenal of maps. Here are our best tips for it.

Published

cod bocw apocalypse tips

The Black Ops Cold War lore has taken us to the jungle, which is why we’ve been able to set foot in the new Apocalypse map. Season 2’s new Jungle-themed map is here, and we’ve come up with some top tips to master it.

Season 2 of Black Ops Cold War really stoked the fire by throwing the FARA 83 and LC10 at us to play with along with the new Apocalypse map. Players now have the opportunity to rumble in the jungle, and there are many different ways to do so.

It’s a medium-sized map with lots of tight corners and rooms with multiple entry points. There are few areas in the map that you can feel ‘safe’ in, so it’s vital you embrace some of these important Apocalypse tips to survive in Black Ops Cold War’s newest map.

1. The Flag A spawn point is dangerous

At the time of writing, the game seems to have a habit of deploying fresh spawns in exactly the same spot near the back of the Flag A area. Therefore it becomes very easy for the enemy team to keeping killing players here and anticipate their movements.

Our best advice is to use the wall in front of you for cover and make a beeline for the house on the right that requires a ladder. At the very least you can provide covering fire to draw fire from your team to escape on the opposite side, or pick off enemies yourself.

2. Watch out for the hidey holes

There are two or three spots on Apocalypse that provide a little window for you to peep your head through and essentially lie in wait for potential victims.

The best part about them is that you are pretty much obscured apart from your head. Make sure to find them and make the most of them.

3. Underground is good

Down one side of Apocalypse is a useful upper and lower channel that you can easily exploit if you’re careful. Its biggest strength, and weakness, is that it’s exposed to the middle section of the map.

If you’re defending it, use the barrels for cover to pick off players coming from the Flag C spawn. If you’re attacking it, always try and approach it from the middle as you have a superior vantage point, especially as you have the benefit of light on your side.

4. SMGs & Shotguns will do the trick

Despite its size, as we said, it has lots of huts and tighter corners which require fast, hard-hitting weapons to conquer Apocalypse.

So something like the new LC10 absolutely shreds, and when you pair it off with something like the Streetsweeper or the Gallo, then you’re in for a good time.

5. Arguably the best spot on the map

Given the height superiority that this cliff-edge offers, the ability to see two opposite sides of the map, and the fact that it’s just a quality spot, this is the location that should command the most presence.

One of the most important things to consider with this view is that players get a healthy eye line of Flag B. Regardless of if you’re defending it or attacking it, you can go a long way to helping keep that area in your team’s favor.

How to get free perks in Black Ops Cold War’s Outbreak Zombies mode

You can earn free perks for yourself in Black Ops Cold War Zombies’ new Outbreak mode through a neat little trick.

Published

on

Black Ops Cold War Outbreak mode

There is a simple new trick that you can use to earn free perks in Black Ops Cold War Zombies’ new Outbreak mode, so here’s how you can get this done.

You’re given very few resources when you hop into the CoD Zombies mode. You’ll have to rack up points by killing the undead so that you can purchase brand new weapons and level up your abilities through the game’s Perk-a-Cola machines.

Spending your limited points on these machines help make the game more interesting, as you get to pick which attribute you want to improve. Cold War Zombies’ new Outbreak mode has this too, but also comes with its own secret trick.

You can follow a strategy that will get you free perks in this mode.

Black Ops Cold War's Outbreak Zombies mode

Perks can usually be found as special drops during a round, and you fight your way towards them to upgrade yourself. Luckily, there’s a better way to get free perks when playing in Cold War’s Outbreak.

You can perform this simple trick repeatedly in different rounds of Activision’s newest Zombies mode. Here’s what you need to do:

  1. Visit the a near the lower farmstead that’s located on the left outskirts of Golova
  2. Head to the area marked by a row of skulls and you’ll find a small radio that’s positioned against a tree
  3. Hold the action button to play the recording
  4. A giant beam will become visible, so make your way towards it
  5. Defeat all the zombies and then collect the free perk drop!

That’s all you need to do, and you can try it on Ruka and Alpine as well. You can do this again by immediately rushing back to the radio’s location and then repeating the process, since there is no limit to the amount of times that you can try this easy trick.

Black Ops Cold War's Outbreak Zombies mode

The best part is that you won’t have to worry about your teammates stealing the drop from you. This is because one player picking it up will result in everyone in the lobby also receiving a free random perk. So don’t worry about one of your teammates trying to cheat you out of buffs.

Outbreak has taken all the best elements of CoD Zombies to create a fresh and exciting new mode. It throws out the past template, and massively deviates from anything that has been in the mode before.

You can keep some powerful weapons to defend yourself in Black Ops Cold War’s Outbreak mode, and you can see all the best ones in our guide.

UPDATE – March 5 at 1:35PM ET: The Black Ops Cold War & Warzone servers are now back up for players on all platforms. Issues may persist as the servers come back online fully.

Original Story.

Activision Support is reporting that they are actively investigating issues with the Call of Duty: Black Ops Cold War & Call of Duty: Warzone servers right now. The issue is effecting players on all platforms.

Some players are getting an error message saying the servers are not online. The message is asking people to re-try and connect to the game.
