The classic Zombies mode in Call of Duty: Mobile continues to thrill players in 2025, offering a nostalgic yet challenging experience that keeps fans coming back for more. With several updates since its reintroduction, the mode has evolved while maintaining the core elements that made it a favorite. Whether you're a newcomer or returning player, this comprehensive Call of Duty: Mobile zombies classic guide will help you survive the undead hordes and conquer the secret boss fights.

Getting Started with Zombies Mode

First-time players will need to complete a brief tutorial that introduces the basics of the mode. After this introduction, you'll need to survive eight rounds in Classic Shi No Numa to unlock the Hardcore mode - which is essential for accessing the more advanced features like the Easter egg boss fight.

Playing solo? Simply uncheck the auto-fill option before starting your match. While teaming up with other players can make survival easier, going solo gives you complete control over the pace and strategy of your game.

Essential Survival Tips

Surviving in Zombies mode requires a combination of smart resource management, strategic movement, and effective weaponry. Here are some crucial tips:

1. Prioritize your points early on - In the first few rounds, knife kills earn you more points than shooting zombies

2. Keep moving - Standing still is a death sentence in later rounds

3. Save a zombie at the end of rounds to give yourself time to explore, purchase perks, or upgrade weapons

4. Learn the map layout - Knowing escape routes and perk locations is vital when hordes get overwhelming

Must-Have Perks

Perks are special abilities that significantly enhance your survival chances. These are the most essential perks in any Call of Duty: Mobile zombies classic guide:

• Juggernog - Increases your health, allowing you to take more hits

• Double Tap - Boosts your weapon's fire rate and damage output

• Stamin-Up - Enhances your movement speed, critical for escaping tight situations

• Quick Revive - Reduces the time needed to revive teammates (or yourself in solo mode with the latest update)

The perk machines are located in huts at the corners of the Shi No Numa map. Each perk costs points, so manage your resources wisely.

Unlocking Pack-a-Punch

The Pack-a-Punch machine is crucial for upgrading your weapons to deal with tougher zombies in later rounds. To unlock it in Shi No Numa:

1. Find two Electronic Components scattered in the perk huts around the map

2. Return to the Pack-a-Punch machine and repair it

3. Upgrade your weapons starting at 2,000 points (cost increases with each upgrade)

The best weapons to upgrade include the Ray Gun Wonder Weapon, Holger 26 light machine gun, RPD light machine gun, and the JAK-12 shotgun - all devastating against zombie hordes after being Pack-a-Punched.

Accessing the Secret Boss Fight

One of the most exciting challenges in Zombies mode is the secret Jubokko boss fight. Here's how to trigger this epic encounter:

Step 1: Fix the Lift

• Collect two large gear-shaped items from the lower level of the main hut

• Interact with the red electrical box on the lift to repair and activate it

Step 2: Enter the Underground Lab

• Take the lift down to access the hidden laboratory

• Turn left from the starting corridor and follow the path

Step 3: Destroy the Plants

• Locate the room with large chemical vats and glass cases

• Shoot the blue glowing plants until they stop spawning

Step 4: Activate the Machine

• Find the nearby machine with a red light

• Interact with it to start the process

• Survive until round 12 for the Jubokko boss to appear

Boss Fight Strategy

The Jubokko plant boss is a formidable opponent with two health bars. Prepare for this fight by:

1. Gearing up properly - Make sure you've acquired all essential perks and Pack-a-Punched your weapons

2. Purchasing armor from the supply machine in the main hut's lower level (starts at 1,000 points)

3. Creating space - The boss will chase you, so keep moving to give yourself reload time

4. Focusing fire - Aim for critical hit areas to maximize damage

5. Using the ammo resupply box available during the fight

Remember that once the boss fight begins, you won't have access to perk machines or Pack-a-Punch, so prepare thoroughly beforehand.
