    • Find two Klaus legs inside Android Assembly. Possible locations include: near the box close to the elevator Klaus Leg Location 1, on the corner shelf near the hanging Klauses Klaus Leg Location 2, in the doorway near where you build Franken Klaus Klaus Leg Location 3, and in the corner with the broken TV screen Klaus Leg Location 4.

    • Place the brain inside the device. Place Brain in Device

    Step 5: Input Folder Code

    • On the Periodic Table of the Elements, find the element that has your letter(s). Periodic Table Element
    • Note its Atomic Number. Since it's a three-digit code, add leading zeros to the Atomic Number to make it three digits (e.g., 2 becomes 002). Input Atomic Number Code

    Step 7: Open The Portal

    • With the Gorgofex acquired, head down to Sublevel 10 and interact with the red button on the terminal. Interact with Sublevel 10 Terminal
    • This will start a timed event where you need to shoot five Quantum Vermin with the Gorgofex (normal shots are sufficient). Shoot Quantum Vermin with Gorgofex

    • Place the Fungal Head inside the full mop bucket. Place Fungal Head in Bucket

    • Pick up and bring the fully charged Fungal Head to the Teleportation Lab. Bring Charged Fungal Head to Lab
    • Interact with the portal to place it inside it. This will spawn items that will stun you and move when you get nearby. Place Fungal Head in Portal

    Step 10: Pre-Bossfight Lockdown

    • Before starting the final lockdown, here are the five levers you'll have to interact with (located around the facility). Levers for Lockdown
    • Activate the machine with the Vacuum-Sealed Devices to start the final lockdown. Activate Final Lockdown
    • Listen for the beeping sound and interact with the red levers that light up to successfully complete the lockdown. (It's recommended to have at least a Pack-3 weapon with gold rarity before starting). Interact with Red Levers

    Step 11: Bossfight

    Now that the lockdown is complete, the bossfight is available. You will have a choice between two paths: the S.A.M. Bossfight or the Richtofen Bossfight.

    Path A: S.A.M. Bossfight

    • For Phase One of the pre-boss fight, you have to fill up three Soulboxes. Fill Three Soulboxes (S.A.M. Bossfight)
    • For Phase Two of the pre-boss fight, you have to shoot the Dark Aether Crystals on the wall. (The more players, the more crystals will spawn). Shoot Dark Aether Crystals (S.A.M. Bossfight)
    • For the S.A.M. Bossfight, there are a couple of openings for attacking her. One is right after her laser attack (you have to shoot her four red cores to expose her eye). S.A.M. Attack Opening 1
    • Another opening is during her spin attack, but be sure to look out for her projectiles. S.A.M. Attack Opening 2
    • After enough damage, she will start a trial. If you fail, you will get a weapon nerf for a brief amount of time. Weapon Nerf from Failed Trial
    • After her first trial, her spin attack will become a bit more intense. Intense Spin Attack
    • Use Aether Shroud after her laser attack to be able to get the most damage in, so zombies aren't on you. Use Aether Shroud for Damage
    • After you shoot all four red cores, you'll be able to shoot her eye even though her shield is up. Shoot S.A.M.'s Eye
    • Once Phase Two is complete, she will start another trial. If you complete the trial, you will be rewarded with a free random perk. Free Random Perk Reward
    • Keep repeating the attack openings from before. Repeat Attack Openings
    • In the final phase, she has an attack that can launch you into the air. Get back to the roof as quickly as you can before she shoots you with an instant kill attack. Dodge Instant Kill Attack
    • In the final phase, she does less laser attacks and more spin attacks, so keep your guard up. Final Phase Strategy

    Path B: Richtofen Bossfight

    • In the first phase of the Richtofen Bossfight, shoot off his shoulder pads to destroy his shield. Also, be sure to dodge/kill all the Kommando Klauses and Uber Klauses, or you're going to get overwhelmed. Dodge & Kill Kommando/Uber Klauses
    • Once his shield is destroyed, he's a lot easier to damage for his first phase. Damage Richtofen (Phase One)
    • When Uber Richtofen is defeated, it's time for phase two. Using Aether Shroud while he is floating around with his jetpack makes you completely invisible from him. So be sure to time your Aether Shrouds with your team to get the most damage in. Aether Shroud for Invisibility
    • After damaged enough, he will go up into the air and come back down for a dive bomb, so be sure not to be in the way. Dodge Dive Bomb
    • Keep repeating the strategy with Aether Shroud to damage him and use Gobble Gums if you want to keep refreshing it. Repeat Aether Shroud Strategy
    • Something to note during this phase is to look out for mines on the ground; they stun and do a good bit of damage. Look Out For Mines
    • As you can see in this footage, it helps a lot to have an Instakill on hand. Instakill on Hand

    Rewards

    • Completing the Easter Egg will reward you with the "BLOOD, SWEAT, AN' GEARS" Operator Skin. Operator Skin Reward
    • You will also receive several Calling Cards related to the Reckoning map. Calling Cards Reward
