Harper enters the Command City of the US during the Fracture mission. Once inside, something transmits through the city’s core systems and transforms him into the strongest enemy in that zone. His body enlarges, his behavior becomes violent, and he attacks you with shockwaves, mouth-bombs, and gas that heals him. The fight becomes a full survival battle as he switches between giant and human forms.
What to know
Harper becomes a phase-changing boss who rotates between a giant mutation form and a normal human form, each with different attacks and weaknesses.

How to fight Harper
Harper’s fight revolves around dodging his huge attacks, hitting his mouth during bomb charges, avoiding the healing gas, and punishing him when he switches to human form.
Step-by-step guide to defeat Harper
Step 1: Dodge opening shockwave
Move sideways when he slams the ground at the start.
Step 2: Mount after big slam
When he lifts both arms high, he becomes open — climb and deal burst damage.
Step 3: Shoot his mouth
He throws bombs from his mouth. Aim there to stagger him.
Step 4: Collect the loot crate
After he falls, a loot crate appears in the arena. Open it to get a Submachine Gun for fast close combat and the AARow-109 Anti-Vehicle Launcher, useful for dealing heavy burst damage on armored enemies in the next mission.
Step 5: Avoid blast zones
Each bomb leaves a dangerous explosion area — move out instantly.
Step 6: Punish the stagger
After hitting his mouth, unload damage while he reels back.
Step 7: Handle human phase
He shrinks to normal size, uses guns, and tricks you. Keep him in open space.
Step 8: Escape healing gas
When he returns to giant form, he releases gas that heals him. Leave that zone fast.
Step 9: Repeat phases
Follow the cycle: Slam → Mouth bombs → Stagger → Human form → Gas → Repeat until he falls.
Harper combat tips
- Always leave the gas area — it restores his health quickly.
- Hit his mouth only when he charges bombs for guaranteed stagger.
- Mounting after heavy slams deals safe damage.
- Stay mobile; his shockwaves punish slow movement.
- During human phase, aim for head and avoid corners.
