Master the Firebase Z Easter Egg with this step-by-step guide and expert strategies
Introduction to Firebase Z Easter Egg
The Firebase Z update brings a thrilling new Zombies experience to Call of Duty: Black Ops Cold War, featuring an intricate Easter Egg challenge that tests both strategy and skill.
Treyarch’s February 4th update transports players to Vietnam’s Firebase Z outpost, where a hidden narrative unfolds through this complex multi-stage puzzle. The Easter Egg went live on February 5 at 5PM GMT/12PM EST/9AM PST, offering dedicated players a rewarding challenge beyond the standard zombie survival gameplay.
Preparation and Setup
Power Activation
Begin by teleporting to Firebase Z’s main compound, where you’ll encounter three distinct gates leading to critical Aether Reactors. Activating these in sequence powers the facility’s core systems.
Aether Reactors
- First Reactor: Located in Mission Control, accessible after clearing initial zombie waves
- Second Reactor: Found within Military Command, requiring defensive positioning during activation
- Third Reactor: Situated in the Data Center, often swarming with special zombies during setup
Pro Tip: Assign team members to guard different reactor locations simultaneously for efficient completion in co-op mode.
Obtaining the R.A.I K-84
Mystery Box Method
The R.A.I K-84 Wonder Weapon can randomly appear from the Mystery Box, though this method offers no guarantees. Budget at least 10,000 points for multiple attempts, and consider using the Fire Sale power-up if available.
Blueprint Method
For guaranteed acquisition, follow these steps:
- Access the Weapons Lab blueprint terminal (requires zombie eye scan at Scorched Defence)
- Search opened lockers for two weapon components
- Eliminate a Level 15+ Mangler for the final charged component
- Return all parts to the Weapons Lab for assembly
Note: The final assembly cannot be completed until the Easter Egg stage officially activates.
Easter Egg Completion
Zombie Eye Puzzle
The Scorched Defence area contains a critical puzzle requiring a zombie’s ocular scan. Lure a zombie to the designated terminal while defending against other undead attackers. This grants access to locked compartments containing weapon blueprints.
Mangler Encounter
Manglers begin appearing at Level 15, identifiable by their armored plating and energy cannon. Target their exposed power core for maximum damage. The defeated Mangler drops the final charged component for your Wonder Weapon.
Warning: Complete these steps efficiently to avoid being overwhelmed by escalating zombie waves during the Easter Egg activation sequence.
Pro Tips and Strategies
- Upgrade armor at the crafting table before attempting reactor activations
- Stockpile Monkey Bombs or C4 for crowd control during critical steps
- In co-op mode, have one player focus on objectives while others manage zombies
- Time your Pack-A-Punch upgrades between rounds for maximum efficiency
- Watch for visual cues in the environment that hint at puzzle solutions
