Call of Duty’sCalling Card challenges are usually pretty easy to complete with its helpful hints. However, the Dark Ops collection remains the most difficult, only labeling it as ‘Classified’ and nothing else.

To give you a look behind the curtain, here’s how to complete allBO6ZombiesDark Ops challenges.

How to complete all Zombies Dark Ops challenges in BO6

Black Ops 6’sDark Ops challenges continue to expand with every new major update. Some objectives are tied explicitly to maps likeLiberty Falls and Terminus. Then, there are the general ones that cover all locations. If you’re a newcomer, theZombiesDark Ops collection isn’t for the faint of heart; these tasks come with the most strenuous quests more suited for veteran players. At the time of writing, the following Dark Ops challenges are available inBO6 Zombies:

The Perkaholic GobbleGum will help you tremendously with various objectives. If you’re lucky, you’ll get it for free by simply playingZombies,as well as purchasing it from the store. The Calling Card, Well That Was a Waste, will come at a cost with this GobbleGum, as you must be downed immediately after consuming it. It’s a double-edged sword since you’ll lose out on some perks, but at least it’ll give you the Dark Ops reward.

Big Game Napalm Burst Augment

In addition to GobbleGums, you must pick up Scorestreaks to earn certain Calling Cards. The Harbinger of Doom, in particular, can be unlocked with Mutant Injection or Sentry Turrets Scorestreaks. You’ll also need a variety of Ammo Mods, both from the Arsenal and the Augments. Ensure to equip your Augments before battling, especially with the Light ‘Em Up’s Big Game requirement.

Be prepared to invest a significant amount of time into theZombiesDark Ops challenges. Even with the best preparations, these tasks will demand your full attention. The key is to work on multiple challenges simultaneously to maximize your efforts. For instance, aiming for Round 100 may provide you with enough eliminations for the monumental Reaper of the Undead.

Liberated Calling Card

Getting to Round 100 may be one of the most difficult ones out there, but there are a few ways to make it easier. I suggest using Liberty Falls for a task such as this, as the map is smaller than Terminus, and it restricts your movement less than Citadelle des Morts. Plus, you can attempt to tackle the Main Quest for even more Dark Ops challenges.

Equipping the classicMustang and Sally buildis my go-to, eliminating a bunch of zombies in a few seconds. For Liberty Falls, ensure you get theJet GunWonder Weapon later on to help you more with crowd control. But if you want to try this out in Terminus for the Terminal Dark Ops challenge, you can opt forthe BeamsmasherWonder Weapon instead.

Citadelle des Mortsseems to be the only map that doesn’t come with a distinctBO6 ZombiesDark Ops objective. There may be one cleverly hidden in there, so I’ll be sure to update this guide if there are more secret finds.
