The latest season has arrived to Call of Duty Mobile, and as the title suggests, Season 9: Zombies Are Back 👍 is an update focused on the undead. The Halloween-themed update also brings the return of the classic Shi No Numa 👍 Zombies map, which features a hidden boss fight. Here is everything you need to know to unlock the option to 👍 complete the Easter egg steps and defeat the boss.
How to unlock Shi No Numa's Easter egg boss
Shi No Numa was 👍 briefly featured in Call of Duty Mobile back in 2024, but the classic Zombies map was removed and eventually replaced 👍 with the objective-style "Undead Siege" mode. Even if you played Shi No Numa the first time it was introduced into 👍 the mobile game, you'll still need to go through these steps to unlock the mode needed to complete the boss 👍 fight.
When you first log onto the game and download the Season 9 update, you'll need to do two things in 👍 order to unlock the ability to access the mode needed for the Easter egg.
First, there is a quick tutorial to 👍 show you the basics of Call of Duty Mobile's Zombies mode. This is pretty straightforward. Afterwards, you'll need to play 👍 one match of Classic (normal) Shi No Numa and survive eight rounds to unlock the option to play the Hardcore 👍 mode. Harcore mode is what you want to play in order to access the boss fight.
Note: You can choose to 👍 play solo or as a squad of four for this easter egg. If you want to play solo, just make 👍 sure you uncheck the auto-fill option before starting the match.
Activate the boss fight
While in a match of Hardcore mode, here 👍 are the steps you'll need to take to activate the boss. You can do all the steps in early rounds, 👍 but the boss won't appear until after round 12, so you'll still have plenty of time to earn points and 👍 get geared up for the fight. You'll want to make sure you're grabbing the gear you need during the regular 👍 rounds, as you'll only get a one minute countdown to get ready for the boss encounter. There will be an 👍 ammo resupply box available during the fight, but you won't have access to perk machines or Pack-a-Punch.
Step 1: Fix the 👍 lift
Shi No Numa's lift
When you start a match of Shi No Numa, you're spawned in the top of the main 👍 hut. Survive the undead until you earn 1,000 points to unlock a door. There's no price difference and either option 👍 will suffice, but I prefer to open the door to the stairs for convenience. Head down stairs when you can 👍 to start looking for parts to fix the broken elevator lift located on the upper level of the main hut's 👍 balcony.
These are large gear-shaped items found on the floor and shelves of the lower level of the main hut. They're 👍 not too difficult to spot, and it will give you the option to pick them up when you get close 👍 to them. You'll need to grab two gear parts to fix the lift.
Step 2: Ride to the underground lab
Once you 👍 have two gear pieces and you're ready for the next step, head up to the balcony and interact with the 👍 red electrical box attached to the lift. You'll have to interact with the box twice for the repairs and a 👍 third time to activate the repaired lift. Now you're ready for a ride.
Step 3: Destroy plants
The lift will transport you 👍 to an underground lab on the map. From the starting corridor, you'll make a left and follow the path to 👍 a room with large chemical vats and glass cases lining both sides of the room. The glass cases have seeds, 👍 and they'll start sprouting into blue glowing plants. You'll want to shoot these blue glowing plants until they stop spawning.
Step 👍 4: Activate the machine
Machine to activate boss fight
The final step requires you to activate a machine in the nearby room. 👍 The machine has a red light, and you'll see a prompt to "start" when you get close to it. Once 👍 activated, you'll need to survive the remaining 12 rounds of the match before the Jubokko plant boss will appear.
Boss fight 👍 tips
Get the essential perks
You'll want a few helpful perks before you fight Jubokko. Juggernog and Double Tap are two essential 👍 perks. These will aid you in boosting your health and dealing more damage to help keep you in the fight. 👍 Another recommended perk would be Stamin-Up. Jubokko is a bullet sponge and will chase you, so you'll want to have 👍 increased speed to help stay ahead of the chase to give yourself some space to reload and such.
Upgrade your weapon
The 👍 Pack-A-Punch machine is crucial here, as you'll definitely want upgraded weapons before heading into the fight. Much like Shi No 👍 Numa's lift, the Pack-a-Punch machine is broken and needs new parts to repair it. There are two small cylinders called 👍 Electronic Components that can be found while opening up the map and getting perks. These two parts will be located 👍 in two of the four of the perk huts found at each corner of the map. Pack-a-Punch upgrades start at 👍 2,000 points and increase with each upgrade.
As for weapon choices, something like the ray gun Wonder Weapon, Holger 26 light 👍 machine gun, RPD light machine gun, or the JAK-12 shotgun would be good to Pack-a-Punch for Zombies.
Grab some armor
While maybe 👍 not the most essential item, you'll likely want to grab some armor if you have enough points to do so. 👍 Armor is found in the supply machine in the lower level of the main hut, starting at 1,000 points for 👍 the first upgrade. You can also buy a custom gun loadout for 3,000 points.
You'll have to chip away at two 👍 health bars to take Jubokko down, but these tips should help you survive the battle.
