You've probably scrolled through your Calling Cards menu in Black Ops 6 and noticed that frustrating "Classified" section. It's empty. No hints. No descriptions. Just a blank box staring back at you. Honestly, it’s one of the coolest parts of Treyarch’s DNA—hiding these brutal, specific challenges that you only find out about by actually doing them.
Campaign Dark Ops BO6 missions are specifically designed to test whether you're just playing the game or actually mastering its mechanics. Unlike the Multiplayer ones that require you to basically be a god-tier professional (looking at you, Very Nuclear), the campaign set is actually achievable for regular humans.

There are only four of them. That sounds easy, right?
Well, "easy" is a relative term when you’re trying to parkour through a mental breakdown or sneak through a CIA black site without a single guard noticing the breeze you leave behind. If you want that Mastery Calling Card, you’ve got to do exactly what the game isn't telling you to do.
The Most Wanted Stealth Run: Phantom Presence
Basically, everyone remembers the "Most Wanted" mission because of the gala and the camera work. But the real challenge starts when you hit the Black Site Intel Center. To unlock the Phantom Presence Dark Op, you have to get through that entire underground facility without being detected.
Don't touch the alarm. Don't let a guard's awareness meter turn red.
The trick here is actually following Marshall’s instructions to the letter. Most people get impatient and try to slide-cancel through the hallways like they're playing a match on Nuketown. Don't do that. Crouch walk. Use your takedowns. There is a specific section on the ceiling catwalks that basically acts as a "get out of jail free" card if you can reach it. If you see that yellow bar over a guard's head start to fill up, just restart the checkpoint immediately. The game tracks it the moment the alert triggers, so don't try to "save" a botched run.
Hunting Season Without the Easy Way: Endless Options
This one is kinda hilarious because it punishes you for using the tools the game literally hands to you. In "Hunting Season," you’re tasked with destroying SCUD missiles. The game screams at you to use C4. It’s the intended way.
To get Endless Options, you have to ignore the C4 entirely.
You need to destroy every single SCUD missile using alternative explosives. We’re talking rocket launchers, grenades, or even explosive barrels if you can lure the targets near them. There are usually launchers scattered around the enemy encampments, so you don't need to bring one in your loadout, but it helps. Just make sure you don't accidentally interact with the prompt to plant the charge. If you hear that "beeping" of a C4 timer, you’ve already failed.
Stashing Bodies in Under the Radar: Missing Persons
"Under the Radar" is one of those classic "wear a disguise and look like you belong" missions. It’s great for world-building, but the Missing Persons challenge is a bit more... macabre. You need to stash five bodies in lockers.
The easiest way to do this is right at the start.
When you get into the first sector to clear the radar, there are plenty of isolated guards near lockers. You take them out, pick them up, and shove them inside. You can actually get all five done in the very first area before you even move on to the SAM sites or the helicopter sabotage. It’s more of a chore than a difficulty spike, but if you're playing on Veteran, it's a bit of a nail-biter trying to move a limp body while a patrol is walking by.
The Parkour Nightmare: Kineticist
Honestly? This is the one that’ll make you want to throw your controller. In the mission "Separation Anxiety," specifically the "Lies" portion, there’s a time trial. To unlock Kineticist, you have to finish it in one single run.
It’s a 30-second timer.
It requires almost perfect movement. You’ve got to jump, slide, and shoot targets without losing your momentum for a single second. The good news is that you can restart the checkpoint as many times as you want. As long as you don't walk through the door at the very end of the course, the game doesn't "lock in" your failure. If you're struggling, try changing your settings to "Automatic Tactical Sprint." It saves your thumb from the clicking and lets you focus entirely on the jumps.
How to Get the Campaign Dark Ops Mastery
Once you’ve ticked off all four of these, you don't just get four calling cards; you get the Campaign Dark Ops Mastery card. It’s easily the rarest thing you can pull out of the single-player mode.
Most people ignore the campaign once the credits roll, but these challenges are why the replayability is actually there. They force you to engage with the level design in a way that feels like the old-school GoldenEye or Perfect Dark era.
Your Next Steps for Completion
If you're looking to wrap these up quickly, here is the most efficient path:
- Start with "Under the Radar": It’s the least stressful. Just hide the five bodies in the first 10 minutes and you can even quit the mission after the challenge pops if you've already beaten the game.
- Move to "Hunting Season": Grab a launcher from the first camp you raid. Use it for every SCUD. It’s tedious but not hard.
- Practice "Kineticist": Do this before "Most Wanted" because it requires a "warmed up" hand for the movement. Once you nail the parkour, your hands will be steady enough for the stealth run.
- Finish with "Most Wanted": Take it slow. This is the one that most people fail at the 90% mark because they get cocky near the exit.
You don't need to play on Veteran to get these. In fact, if you just want the cards, drop the difficulty to Recruit. It doesn't invalidate the Dark Ops, and it makes the SCUD missile part much less of a headache when you're being shot at from three different angles.
