Despite being out for several months, Outbreak’s main Easter Egg hasn’t been available until now. Our full guide will walk you through it every step of the way in Black Ops Cold War’s Zombie mode.

Testament to Treyarch, as they have not only found a way to reinvent Zombies and make the concept seem more alive than ever, but they keep doing their best to add to it. For weeks, CoD Zombies players have had to contend with horrifying enemies and even the odd horrifying glitch too.

But Black Ops Cold War Season 3 Reloaded has carried on the forward push to make Outbreak bigger and better with a new fishing activity, and now the game’s main Easter Egg.

As with most Call of Duty Easter Eggs, the main Outbreak one is convoluted, will take some time, and requires a lot of groundwork. So strap yourself in.

Reach Round 3 in Outbreak Zombies

To actually start making headway towards the main Easter Egg, you will first need to reach Level 3 in Cold War Outbreak. As with any other game of Outbreak, it’s a case of maximizing your first couple of rounds to ensure you get your weapons Pack-A-Punched, trying to obtain Wonder Weapons, and acquiring Perks.

Be patient, collect and do everything, finish the level objectives and side missions, then move onto Round 3.

Find the radio

Somewhere on your designated level will be a radio to find. It’s up to you whether you ignore everything else and just go radio hunting, but given the vastness of the environments, you might be better off just playing normally.

For this, we recommend turning your in-game subtitles on, as nearing the radio will actually come up with “Radio: [inactive idle static],” meaning it’s close by.

Once you manage to locate it, approach it and press the action button to “Listen to signal.” It will then emit frequency feedback that sounds like crackling and bells. This will then trigger a big wave of Zombies for you mow down with the best Outbreak weapons.

Search for the Amplifiers

Whilst the Radio continues to transmit feedback, you’ll now need to go and find three Amplifiers in the vicinity of the Radio. Again, as long as you’ve got the in-game subtitles on, nearing one will prompt you with “Amplifier: [inactive idle static].”

Find and trigger all three so that they activate, and then make your way back to the original radio to listen to a message from Samantha Maxis, and pick up the part that the Radio produces.

The beacon

Usually your gateway to the next round, the beacon will instead be the home for the part that you picked up. You then speak with Samantha Maxis properly and move onto Round 4.

Round 4 & the monkeys

Once Round 4 begins, you will need to hunt for stone monkeys until you find the right one signposted with an “M” next to it. It should also drop some Microfilm Slides once you’ve shot it.

This process can be lengthy and exhausting without the correct knowledge, and we credit YouTuber TheRealGhost for creating a video that shows the location of all the monkeys on all the maps.

The projector

With film in hand, it’s time to locate a projector to use the Microfilm Slides on. Each map has different locations of course, and here’s where you’ll be able to find projectors:

  • Alpine – Central Lodge, 2nd Floor, south side (PAP Building)
  • Duga – Admin Offices, 2nd Floor, Big L-Shaped Building, on the south side of Duga
  • Golova – Police Station
  • Sanatorium – Administration Building, top-left of map

When all the slides have been watched, you’ll now need to move onto Round 5 – automatically taking you to the Ruka map.

Round 5 – Ruka, Silo & Launch Keys

Once you arrive head for the objective that includes an elevator taking you down to the depths of the Silo below. Head to Silo A, and “Lift the Lockdown” by deactivating a switch.

You’ll then be tasked with a new objective – “Find the Launch Keys.” Following the basic rule of three, you have to locate them all and they are all situated in the Silo’s depths.

Here’s where you can find all the Launch Keys:

  1. Key One: It can be found in a dead-end corridor lit by ominous red lighting. Kill the special Mimic and claim the first key.
  2. Key Two: Found near Silo B, you’ll need to deposit Aetherium Crystal Chunks in an “Aetherium Harvesting Unit” which can be found in the Silo. Deposit 20, and you’ll receive the Aetherium Blast ability. Go and find the Jellyfish located nearby, get close, and use the ability. The jellyfish will pull you in towards it, and you can collect the second key
  3. Key Three: Collect an Essence Trap from another dead-end in Silo A, and find a vent emitting a blue glow. Set the trap below the vent, back away, and wait for a monkey to become ensnared in the trap and captured. Acquire the trap, and you’ll get the third and final key.

Start the Launch Sequence

It’s now time to approach the end of this journey. With all three keys, you’ll need to quickly go around all three silos and “Insert Launch Key.” Doing so will trigger a timer, so you need to head to the middle room to be able to ascend the stairs and “Get to the Surface.”

Defeat Legion

Exit the elevator and you will see a huge presence warp into the map, and your final mission in the Easter Egg is to simply “Kill Legion.

As you can expect, the boss has a whopping health bar, summons minions and Zombies to help, and will take a titanic effort to beat it. But if you are successful, then you will not only be victorious, but you will get to see the final cutscene, and complete the Easter Egg.
