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 make this challenging task significantly easier.

Best Maps and Modes for the Harbinger of Doom Challenge

While Black Ops 6 Zombies offers Standard, Directed, and Jingle Hells modes, Standard mode provides the largest and most consistent zombie hordes, making it ideal for this challenge. Open areas are key for maximizing killstreak effectiveness. Therefore, locations like the Shipwreck on Terminus and the Liberty Falls spawn area near Pump & Pay are prime choices due to their spacious layouts.

The Best Killstreaks for Maximum Zombie Destruction

For this challenge, the Chopper Gunner and Mutant Injection stand out as the most effective Support items. The Chopper Gunner provides aerial minigun support, while the Mutant Injection transforms you into a powerful Mangler. Both offer invulnerability and exceptional damage output.

High-ranking players can craft these at a workbench for 2,500 Salvage. Alternatively, killing special enemies, completing S.A.M. Trials, or using Loot Keys on Terminus and Liberty Falls offer a chance to acquire them, although this relies on RNG. Crafting beforehand is highly recommended.

Strategic Approaches for Success

Aim for rounds 31-40 to ensure maximum zombie density. Activating the Rampage Inducer further boosts zombie spawns and speed, creating ideal conditions for a swift killstreak.

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

Chopper Gunner Strategy: Assemble 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 its devastating firepower from above.

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