Mastering the Harbinger of Doom Dark Ops Challenge in Call of Duty: Black Ops 6

Call of Duty's rewarding killstreak system takes center stage in Black Ops 6 Zombies, where they function as potent Support items for decimating hordes. The Dark Ops Challenge "Harbinger of Doom" tasks players with achieving 100 zombie kills using a single killstreak. This guide outlines the optimal strategies for success.

Optimal Maps and Modes

Black Ops 6 Zombies offers Standard, Directed, and Jingle Hells modes. While Directed is popular for camo grinding, its smaller hordes make it unsuitable for this challenge. Standard mode is the ideal choice.

Map selection is crucial for maximizing killstreak efficiency. Open areas are key for maximizing the killstreak's area of effect. Excellent locations include:

• The Shipwreck on Terminus
• The Liberty Falls spawn area near Pump & Pay

Top Support Items

Two killstreaks stand out for this challenge:

• Chopper Gunner: Rains down devastating minigun fire from above.
• Mutant Injection: Transforms the player into a powerful Mangler for a limited time.

Both offer invulnerability and significant damage output. These can be crafted at a workbench for 2,500 Salvage or obtained through chance encounters (killing special enemies, completing S.A.M. Trials, or using Loot Keys). Crafting is recommended for reliability.

Effective Strategies

High-round gameplay is essential. Aim for rounds 31-40 to maximize zombie spawns. Activating the Rampage Inducer further boosts zombie density and speed.

Mutant Injection Strategy:

1. Gather a large horde in a confined area with multiple spawn points (e.g., Rec Yard on Terminus, Backlot Parking on Liberty Falls, Oubliette room on Citadelle des Morts).
2. Activate the Mutant Injection.
3. Utilize melee attacks aggressively to maximize kills.

Chopper Gunner Strategy:

1. Assemble a large horde in an open area (e.g., Shipwreck on Terminus, Backlot Parking on Liberty Falls, Town Square spawn area on Citadelle des Morts).
2. Call in the Chopper Gunner and unleash its aerial firepower.

By following these strategies and choosing the right map and killstreak, you'll be well-equipped to conquer the Harbinger of Doom Dark Ops Challenge and claim your reward.
