Playing the Call of Duty: Black Ops 7 Zombies (BO7 Zombies) mode can be thrilling — but when the formidable foe OSCAR shows up, things get serious. OSCAR isn’t a regular zombie; he’s a powerful robotic elite enemy with special defenses. In this guide, we break down how to kill OSCAR in BO7 Zombies — with smart strategy, right gear, and teamwork.
OSCAR patrols the map (notably in certain map areas) and brings more than just brute strength. He:
- Regularly spawns UFO-like drones that shield him, making him immune to damage while the drones are active.
- Uses powerful laser attacks and buffs nearby zombies to make them stronger and faster.
- Has higher health and resilience compared to normal zombies.
Because of that, a careless run-and-gun approach rarely works. But with preparation and strategy, you can bring him down.
Prepare Before You Engage
Before you attempt to fight OSCAR, make sure you’ve done this:
- Get solid armor and perks. Early on, investing in at least Tier 2 armor is more important than spending your resources on early upgrades or perks. With stronger armor, you survive longer when zombies and elite enemies hit hard.
- Upgrade your weapons and gear. Use the game’s upgrade system to increase your gun’s rarity (damage output), making your weapons more effective.
- Choose useful ammo mods and lethal/tactical equipment. Not all ammo mods work equally, so pick those suited to clearing crowds or dealing with drones and zombies. Equipment like grenades or tactical tools can help with crowd control or escape.
Best Strategy to Kill OSCAR
Focus on the drones first
Because OSCAR’s drones shield him, your first priority should be eliminating them. Drones don’t have huge health, so even standard bullets will work — though with mods you might be more efficient. Once drones are down, OSCAR becomes vulnerable.
Use the right ammo mod: Brain Rot
Surprisingly, OSCAR is not weak to elemental ammo mods — none of them directly affect him while drones are active. However, his drones respond well to the Brain Rot ammo mod. Using Brain Rot ammo helps take down drones faster, clearing the shield quicker and letting you damage OSCAR’s health.
Bait him into a trap — environmental traps are powerful
BO7 Zombies maps contain environmental traps scattered throughout. These traps deal heavy area damage when triggered, and they can work wonders against tough elite enemies like OSCAR. If you lure OSCAR near one of these traps and activate it, you can significantly damage or even eliminate him.
One effective trap is located along certain rocky paths near observatory-type areas. If you lead OSCAR to this trap and spend in-game resources to trigger its rocket bombardment, it can shred his health quickly. Even if it doesn’t fully kill him, it severely weakens him, making the rest of the fight manageable with guns.
Use firepower + teamwork
Once the drones are gone and/or after traps, focus on dealing damage. Using powerful weapons — especially ones upgraded through the game’s upgrade mechanics — will kill him faster. Also, fighting in a group helps: teammates can draw some of the zombies or drones away, while someone focuses fire on OSCAR. Prioritize headshots or sustained damage to bring his HP down quickly.
General Zombie-Killing Tips That Help With OSCAR
- Aim for critical kills — headshots deal much more damage than body shots. With certain perks that improve headshot aim or damage, you get better results.
- Use tactical equipment for crowd control or emergencies. When zombies start overwhelming you, stun grenades or explosives can give breathing room. Tools like semtex or tactical grenades help clear crowds or buy time to reload or reposition.
- Rotate or reposition often — camping in one spot rarely works, especially in BO7 Zombies maps. Zombies spawn in waves, coming from different angles, and elite threats can flank you. Keep moving to reduce risk.
- Conserve ammo in early rounds — don’t waste powerful weapons on simple zombies early. Save them for elite threats or later rounds where damage matters more.
What Happens After You Kill OSCAR
If you manage to kill OSCAR, you often get extra resources, experience, and progress toward certain challenges or rewards. It can also give you a breather to explore more of the map, grab loot, or complete side objectives. However — be ready: OSCAR may respawn later, and you’ll need to repeat the process.
