Resident Evil 9 Bloated Zombie Boss Guide: Seminar Room Cheese & Third Floor Shotgun Execution

The Bloated Zombie in Resident Evil 9 hits like a truck and absorbs more punishment than three standard walkers combined, sending countless players to the game over screen in both the Seminar Room and Third Floor encounters. Whether you are stuck trying to grab that ID Wristband or desperate to clear Leon's path through the Nursing Home, this guide gives you the exact door-cheese tactics and shotgun execution combos needed to drop this fatty fast without burning through your entire inventory.

New Player Essentials: New players often waste all ammo trying to face-tank this boss. The Bloated Zombie has massive health pools and devastating melee range that one-shots you on Hard mode. In the Seminar Room, use the Research Director's Office doorway to trap him permanently. In the 3rd Floor fight, grab the MSBG 500 shotgun immediately for the stun-lock potential. Always aim for the head to trigger knockdown state, then execute with your axe for massive damage conservation.

1. Seminar Room Encounter: Door Cheese Strategy

Head toward the Seminar Room and spot the ID Wristband on the corpse. The moment you approach, the Bloated Zombie crashes through the wall to ambush you.

Do not run downstairs. He will chase you all the way down and trap you in a dead end. Instead, immediately backpedal into the Research Director's Office. He will get stuck in the doorway and cannot enter the room, giving you free shots.

Fire one Requiem round into his head to stagger him, then unload your handgun into his face while he is stuck. If he turns away, step out to bait him back to the door, then duck inside and continue shooting. Repeat this until he dies and drops the Watcher Charm.

Alternative Methods:

1. Lure him downstairs, circle behind him, and inject several Hemolytic Syringes into his back for massive damage.

2. If you are low on supplies, just bait him downstairs, grab the ID Wristband, and come back to kill him later when you have more ammo.

2. ID Wristband and Watcher Charm Reward

Once he is dead, return to the hallway and grab the ID Wristband Level 1 from the corpse. This item is mandatory for progressing through the facility. The Watcher Charm he drops boosts your critical hit rate, making it worth the ammo investment.

3. Third Floor Encounter: Leon's Shotgun Battle

Location: Nursing Home Third Floor

During Leon's campaign segment, exit the Medical Supplies Storage room and enter the attic area.

You will find the Bloated Zombie feasting on a corpse. Sneak up and grab the MSBG 500 Shotgun right next to him, then immediately open fire.

Blast his head with the shotgun until he collapses to the floor stunned. Rush in immediately and execute him with your axe while he is down. This deals massive damage and saves shotgun shells.

You can also lure him to any doorway. He will get temporarily stuck in the frame, giving you free time to unload into his skull.

4. Environmental Exploits and Loot

Explore the attic thoroughly to scavenge supplies and memorize the layout.

Breakable Walls: Some supplies hide inside breakable walls. Lure the Bloated Zombie near these walls and let him charge into them. His impact destroys the wall, revealing the loot inside.

High Ground Advantage: Look up to spot ladders. Climb up to find additional supplies and gain an advantage.

Shoot his head from above, then perform a jumping axe execution for cinematic damage.

Defeating this Bloated Zombie drops Shock Grenades, perfect for crowd control in the next area.

Key Takeaways:

1. In the Seminar Room, use the Research Director's Office door to cheese him. Never go downstairs.

2. The MSBG 500 shotgun on the Third Floor stuns him fast. Always follow up with axe executions.

3. Lure him into doorways or breakable walls to exploit his poor pathfinding.

4. The ID Wristband is essential for progression. Do not skip this fight entirely.

5. High ground gives you free shots. Use ladders to reset the engagement.
