Firebase Z Easter Egg Guide takes you from the Village teleporter to three Aether Reactors, then into a long Main Quest built around Peck, truth serum, Mimic memories, Aetherium crystals and the RAI K-84. The final stage rescues Samantha Maxis before an Orda boss fight, so this is a quest where preparation matters more than raw round count.
This Firebase Z Easter Egg Guide is designed to be followed in order, but several setup jobs can be completed while you are waiting for the right enemies or Mimic spawns. Get the RAI K-84 early if possible, keep armor repaired, and avoid pushing the final satellite step until the team is ready for the closing fight.

Turn on Power
The first stage of the Firebase Z Easter Egg Guide starts in the Village. Speak to Ravenov, open the route to the rooftop and use the teleporter to reach Omega Base. Your main goal is to activate the Aether Reactors in Military Command, Mission Control and Data Center.
Each reactor costs 500 Essence to start. Once activated, stay in the marked area and kill the attacking zombies while protecting the Collector points. Complete all three reactor defenses and the base power comes online.
Activate Pack-a-Punch
With power restored, the Firebase Z Easter Egg Guide sends you back through the teleporter to the Village. Speak to Ravenov again and the Pack-a-Punch machine beside him becomes available. The usual upgrade costs apply, with later tiers becoming increasingly important before the boss.
This is a good moment to start working on the RAI K-84. You can build it through its dedicated quest or obtain it from Trials or the Mystery Box, but you will need its alternate fire later for one of the Aetherium containers.
Gas Peck With Truth Serum
Return to Mission Control for the next Firebase Z Easter Egg Guide objective and speak to Peck through the window. After he refuses to cooperate, go back to Ravenov and collect the ID Card. It opens three lockers containing the compounds needed for truth serum.
- Equipment Storage in the Village holds one compound.
- The Colonel’s Office above Military Command holds the second.
- Engineering on the lower Mission Control side holds the third.
Take all three compounds to the Chemical Mixer in Field Hospital and create the Agent Delivery System. Hellhounds attack during the mix, so clear the room before starting. Carry the finished canister to the OPC ventilation unit above Mission Control and insert it to pump the serum into Peck’s office.
Firebase Z Easter Egg Guide: Capture the Three Mimic Memories
The Mimic stage is where the Firebase Z Easter Egg Guide can slow down. Peck directs you to the Data Center, where you collect Essence Traps. The correct Mimics are not ordinary random Mimics; they appear disguised among fake loot piles in specific areas.
Trigger one, damage it until its health is low, throw the trap underneath it and activate the trap by double-tapping reload. Return each captured essence to the Data Center terminal. You need three correct memories before the terminal gives you the floppy disk. If a capture is wrong, keep hunting rather than forcing the same location repeatedly.
Open the OPC
Insert the floppy disk into the Planning Offices computer to continue the Firebase Z Easter Egg Guide. The OPC portal opens but lacks enough power, sending you back to Peck. Collect the shovel from Scorched Defense and the Aetherium Meter from the locker near Peck’s window.
These two items allow you to dig up the three Aetherium containers. The containers can be completed in any order, but each has a different mechanic.
Collect the Three Aetherium Containers
The three-container section is the most distinctive part of the Firebase Z Easter Egg Guide. At Open Lot, dig up the crystal and identify the real one among the decoys. At Jungle Defense, survive inside the protective dome until the fight ends. At Barracks, use the RAI K-84 alternate fire to stop the moving container long enough to pick it up.
Carry each recovered container to an Aether Reactor and insert it. Once all three reactors are charged, return to the OPC and watch the next sequence.
Align the Satellite
Near the end of the Firebase Z Easter Egg Guide, use the Planning Offices computer and move the on-screen cursor to the satellite marked with a question mark. Confirm the correct target, then make your final preparations before activating the OPC computer.
This is the point to buy armor, ammunition, perks and useful Support equipment. A strong Pack-a-Punched weapon and the RAI K-84 make the final encounter much easier, especially when the arena fills with normal zombies.
Rescue Maxis and Defeat Orda
Activating the OPC moves the Firebase Z Easter Egg Guide into its ending. After the story sequence, the team returns toward the Village and Orda appears as the final boss. Focus heavy damage into Orda while controlling the horde rather than becoming trapped in the courtyard.
The RAI K-84 is effective against the boss, and high-damage Support can shorten the fight significantly. When Orda falls, the closing cinematic plays and the Firebase Z Main Quest is complete.
