How to Kill 100 Zombies with One Killstreak in Call of Duty: Black Ops 6

Conquering the "Harbinger of Doom" Dark Ops Challenge in *Call of Duty: Black Ops 6* Zombies requires eliminating 100 zombies with a single killstreak—a feat best achieved using powerful Support items. This guide outlines the optimal strategies and locations to maximize your chances of success.

Best Maps and Modes for the Harbinger of Doom Challenge

Black Ops 6 Zombies offers several modes, including Standard, Directed, and Jingle Hells. While Directed mode is popular for camo grinding, its smaller hordes make it unsuitable for this challenge. Standard mode provides the necessary density of zombies.

Optimal map selection prioritizes open areas for maximum killstreak effectiveness. The Shipwreck on Terminus and the Liberty Falls spawn area near Pump & Pay are ideal due to their spacious layouts.

Top Killstreaks for Maximum Zombie Elimination

The Chopper Gunner and Mutant Injection are the most effective killstreaks for this challenge. The Chopper Gunner unleashes a devastating minigun barrage from above, while the Mutant Injection transforms the player into a powerful Mangler. Both offer invulnerability during activation, ensuring high kill counts.

These Support items can be crafted at a workbench for 2,500 Salvage once you've progressed in Military Ranks. Alternatively, they may drop from special enemies, S.A.M. Trials, or Loot Keys on Terminus and Liberty Falls (though this relies on RNG). Crafting is recommended for guaranteed access.

Strategies for Success

Attempting this challenge between rounds 31-40 is recommended, as larger zombie hordes spawn at higher rounds. Activating the Rampage Inducer further increases zombie density and speed, creating an ideal killstreak environment.

Mutant Injection Strategy: Train a large horde in a confined area with multiple spawn points (e.g., Rec Yard on Terminus, Backlot Parking on Liberty Falls, or the Oubliette room on Citadelle des Morts). Activate the Mutant Injection and aggressively use melee attacks to maximize kills.

Chopper Gunner Strategy: Gather a large horde in an open area (e.g., Shipwreck on Terminus, Backlot Parking on Liberty Falls, or Town Square on Citadelle des Morts). Call in the Chopper Gunner and unleash the aerial firepower.

By following these strategies and utilizing the optimal killstreaks and locations, you'll significantly increase your chances of completing the Harbinger of Doom Dark Ops Challenge in Call of Duty: Black Ops 6.
