Master Firebase Z’s upgraded Monkey Bombs with this step-by-step guide and pro tips
The Iconic Monkey Bomb
Since its debut in World at War, the Monkey Bomb has become legendary in Zombies lore. This explosive distraction device combines tactical utility with nostalgic charm, featuring a wind-up monkey toy that lures zombies before detonating.
What makes Firebase Z special is its unique upgrade system. While most Zombies maps limit the bomb’s effectiveness, this Cold War installment introduces a powerful enhanced version. The upgraded variant boasts increased blast radius and duration, making it viable even in late-game scenarios where standard versions become obsolete.
Upgrade Requirements and Steps
Unlike conventional upgrades through Pack-A-Punch, enhancing Monkey Bombs requires completing specific challenges. This hidden mechanic functions similarly to Easter eggs, rewarding players who discover and complete the requirements.
Key prerequisites:
- Activate all three Aether Reactors (complete the main power sequence)
- Purchase a Monkey Bomb from the Equipment Crafting Station (costs 1,250 Essence)
The upgrade process:
- Equip your Monkey Bomb near an active Aether Reactor
- Eliminate exactly 50 zombies using the bomb (kills must be direct explosions)
- The next deployed bomb will automatically be upgraded
Pro Tip: The Data Center’s upper level offers ideal conditions for farming kills, with tight corridors that concentrate zombies for maximum efficiency.
Advanced Strategies
Timing your upgrade attempt significantly impacts success. Early rounds (10-15) provide manageable zombie density, while higher rounds require careful planning.
Optimal locations ranked:
- Data Center Upper Level: Narrow walkways create natural choke points
- Motor Pool: Open area allows better visibility and escape routes
- Village: Central location with multiple access points
For team play, coordinate with one player focusing solely on bomb kills while others handle crowd control. Equip Ring of Fire for damage amplification during critical moments.
Common Pitfalls to Avoid
Many players fail the upgrade by making these avoidable errors:
- Incomplete Power Activation: All three reactors must be fully operational
- Miscounting Kills: The game doesn’t track progress, so maintain your own count
- Premature Throws: Wait for optimal zombie clustering to maximize each bomb
- Wrong Upgrade Timing: Attempting during boss waves or special rounds wastes resources
Remember: The upgrade only applies to your next throw after meeting requirements, so plan your final bomb deployment strategically.
