How To Defeat Oscar in Black Ops 7 Zombies & Unlock the LGM-1 Wonder Weapon
Black Ops 7 Zombies players quickly learn that Oscar is more than just another undead threat. He’s tanky, immune to normal damage at first, and designed to push you into exploring the map’s traps and elemental mechanics. But once you understand how his shield works — and the three core takedown methods — grabbing the LGM-1 wonder weapon becomes much easier.
Below is the complete step-by-step guide to defeating Oscar in Black Ops 7 Zombies and unlocking the LGM-1.
🔋 How Oscar’s Shield Works
- Oscar starts protected by circling drones that generate an impenetrable shield.
- Standard shots, explosives, and abilities won’t hurt him until those drones are destroyed.
- Equip Brain Rot elemental ammo — it shreds the drones quickly.
- Pick up a downed drone after destroying one. It’s required later for the final trap.
💡 Tip: Oscar does not aggressively chase players. If you bump into him and aren’t prepared, sprint away and regroup.
☀️ Method #1 — The Solar Beam Trap (Fastest Kill)
Once power is activated:
- Head to the Pack-a-Punch area.
- Shoot the steam valves in the room to enable the sunlight mechanism.
- Lure Oscar to the platform between the Pack-a-Punch machine and the organ.
- Interact with the telescope and aim at the sun.
- A concentrated beam of light will fire down, eliminating Oscar instantly.
This is the quickest and cleanest way to drop him once his shield is removed.
❄️ Method #2 — Cryofreeze & Rocket Blast
To use the rocket trap near the museum:
- Apply Cryofreeze elemental ammo to your weapon.
- Shoot Aetherium Crystal clusters (glowing purple rocks).
- Collect three Absolute Zero shards that they drop.
- Take them to the model rocket in the museum.
- Position Oscar behind the rocket, then fire it.
Kaboom — Oscar is toast.
⚡ Method #3 — Luminarium Overcharge (Grants the LGM-1 Reward)
This method is the most involved but necessary to unlock the LGM-1 wonder weapon.
Collect three components:
- Downed Drone — from Oscar’s drones (Brain Rot required)
- Car Battery — locate Ol’ Tessie, the old pickup truck near spawn; shoot the hood with a Pack-a-Punched weapon
- Aberrant Wires — search for a blinking lamppost anywhere on the map and interact to collect
Once all three are obtained:
- Go to the Luminarium.
- Activate the trap.
- Keep Oscar within the overcharge zone until it destroys him.
After this kill method is completed, Oscar will eventually respawn — but the LGM-1 will be yours.
💣 Bonus Option — Non-Quest Traps (Damage Only)
If you just want Oscar gone quickly — without earning the wonder weapon — other purchasable traps work too:
- Apogee Annihilator — located in the rocky area outside the observatory
→ Calls in a barrage of rockets that chunk Oscar’s health if he’s nearby.
Effective for survival, but won’t unlock the LGM-1.
🎮 Final Thoughts
Oscar may look unkillable at first, but each shield drop and trap activation brings you closer to dominating the Astra Malorum map. Whether you prefer precision (solar beam), explosive style (rocket blast), or full-on puzzle completion (Luminarium), you’ll eventually take him down and walk away with the LGM-1 wonder weapon in hand.
