To beat the hardest boss in Call of Duty Mobile—specifically the Abomination and Jubokko found in the classic Zombies and Undead Siege modes—you must equip the Packed-Up DL Q33 sniper rifle or RPD with Infinite Ammo, maintain constant lateral movement to avoid charge attacks, and target critical head hitboxes during vulnerable recovery frames. Overcoming these brutal health pools requires precise class setups, rigorous resource management, and understanding every single telegraph in their multi-phase attack patterns.
Understanding the Hardest Boss Encounters
Call of Duty Mobile features intense PvE boss fights that test even veteran players. Whether you are tackling the underground laboratory boss Abomination or navigating the terrifying roots of Jubokko, understanding their mechanics is non-negotiable.

The Abomination relies on aggressive forward charges, toxic gas spews, and tracking laser beams, while Jubokko bombards the arena with spore pods and underground vine spikes that instantly down players who stand still.
Before stepping into the arena, you should familiarize yourself with official game mechanics and patch notes via the Official Call of Duty Mobile Website and cross-reference community strategies on the Call of Duty Wiki. Preparing your squad requires coordinating roles: at least one player must run Medic for healing persistence, while the remaining operators focus purely on high-DPS output using upgraded light machine guns and assault rifles.
Optimal Weapon Loadouts and Upgrades
Surviving the relentless damage output of high-tier mobile bosses demands optimal weapon scaling. You cannot rely on base-level weapons found on the wall. You must utilize the Pack-a-Punch machine (or upgrade terminals in Undead Siege) to maximize your firearm's damage multiplier up to Level 5. The absolute best weapon choices for melting boss health bars include the RPD equipped with the 200-Round Conrited Ammo barrel for sustained fire without reloading, and the HS0405 shotgun packed with Dragon's Breath rounds for devastating close-range burst damage during staggers.
Furthermore, pair your primary weapon with Deadshot Daquiri and Juggernaut perks. Deadshot Daquiri automatically snaps your crosshairs to the boss's critical hit zone—the glowing core on the Abomination or the central glowing bulb on Jubokko—massively increasing your critical hit percentage.

Always keep a stack of Max Ammo and Insta-Kill power-ups saved in your inventory wheel for emergency phases.
Phase-by-Phase Strategy for the Abomination
The Abomination boss fight is split into three distinct phases governed by its remaining health percentage. In Phase 1 (100% to 70% health), the boss primarily uses physical melee swipes and straightforward charges. Sprint in a wide circular motion around the perimeter of the containment room. When the Abomination rears back to roar, stop running, aim down sights, and unload directly into its exposed inner mouth. This interrupts secondary animations and deals critical damage.
In Phase 2 (70% to 30% health), the boss summons waves of Undead minions while emitting periodic shockwaves. Do not waste ammo on the basic zombies; instead, let your teammates clear them with grenades while you focus heavy ordnance on the boss's chest plates. When the boss drops to Phase 3 (below 30% health), its movement speed doubles, and it begins firing homing electric projectiles. Use the central pillars as line-of-sight cover, peeking out only after the electricity bolt shatters against the concrete barrier.
Mastering the Jubokko Encounter
Jubokko introduces verticality and area denial mechanics that punish stationary players. The arena fills with poisonous spores that drain your health over time if you linger in toxic green zones. Equip the Hardline perk to earn Scorestreaks faster, and deploy Goliath armor units or Stealth Choppers if the game mode allows them. When Jubokko burrows underground, watch the wooden floorboards carefully; a glowing red particle effect indicates where its massive roots will erupt upward.
As soon as you spot the telegraph, dodge-roll or sprint away immediately. Once the roots breach the surface and remain stationary for three seconds, they enter a vulnerability window. Pummel these roots with high-explosive launchers like the SMRS or XM8 to trigger a massive stagger effect on the main tree trunk.

Advanced Tips for Flawless Victory
Achieving a flawless victory against Call of Duty Mobile's hardest bosses requires mastering advanced movement mechanics such as slide-jumping and drop-shotting to minimize incoming projectile damage. Never reload in the open; always time your reloads immediately following a boss charge attack when they pause to recover balance. Coordinate voice comms with your squad so that only one player draws aggro while the others flank from opposing 90-degree angles to maximize crossfire damage bonuses.
Finally, monitor your armor plates and health regeneration constantly. If your armor breaks, disengage from the boss entirely, pop a Smoke Grenade to obscure vision, and use adrenaline shots behind solid cover before re-engaging. By sticking to these strict tactical guidelines, upgrading your arsenal to maximum level tiers, and respecting boss telegraphs, you will consistently conquer the most challenging encounters Call of Duty Mobile has to offer.
