Game Guide by Joyramen on Dec 02, 2025

The Eat This Calling Card in Call of Duty: Black Ops 7 - Zombies is one of the more straightforward challenges.

One of the fastest methods is to follow a strategy in the farm area, as a specific area makes it easier to gather a large horde of zombies.

Your goal is to reach Round 20 as quickly as you can, as Round 20 features numerous enemies that are enough in quantity for you to complete the challenge in a single attempt. This guide will explain how.

Before initiating the round, you'll want to make sure that the Rampage Inducer is active so that the zombie spawns are sped up. When round 20 arrives, you'll want to head to the crafting bench and build the HKD Streak.

The streak allows you to complete the entire challenge in a single round.

After crafting it, you'll need to gather all of the zombies by running around the open fields of the farm until they group up in a single horde.

I recommend activating the Kill Joy Gobblegum if it's available to you to make the process easier. But if it's not available to you, you can still grab the Kill Joy perk on top of the silo beside the farm that you can use before the round starts to get the effect.

Once the zombies are all gathered up in a horde, you will want to deploy the HKD Streak. Your objective should be to keep the zombies as bunched up as you can to wipe all of them out in a single go.

In a lot of the runs, the HKD will clear around 40 zombies instantaneously, and this excludes the second strike, which can kill additional zombies.

Since the density of zombies is pretty high after round 20, he should be able to get the Calling Card without much difficulty.
