If you’re the kind of player who can’t rest until every box is ticked, the Dark Ops challenges in BO7 are where the real bragging rights live. These hidden objectives don’t tell you what you’re chasing until you’ve cracked them, which makes every unlock feel like a personal win. We’ve dug up 24 so far across the different modes, though a couple are apparently off the table now. That’s a bit of a kick in the teeth, but it hasn’t stopped folks grinding away. Right now, we’re looking mostly at the Campaign set, and some of them are savage enough to make you think about CoD BO7 Boosting just to stay sane.
 One of the nastiest so far is Absolute Loss. You’ve got to take down Menendez in the Exposure mission using only machetes. No guns, no grenades, no fancy tricks – it’s pure close-range steel versus one of the game’s big-name foes. Getting in close without getting shredded can take more than a few tries. Then there’s Dream Team – a grind-heavy one in Endgame mode. Escape Zone IV not twice, not ten times, but 25 successful runs. You start to feel every single one. For weapon lovers, Exotic Arsenal asks for eliminations with six different exotic weapons. Finding these rare guns is half the job, but landing kills with all of them can be real hit-or-miss… sometimes literally.
 If you’re into damage-free runs, Green Thumb is your arena. You’ve got to take out the Nightmare boss in Distortion without a scratch. That means knowing exactly when it’s winding up an attack and nailing your dodges every time. There’s also Monkeying Around in Endgame, which is more about exploration than bloodshed – find and finish both a hidden dive course and a parkour course. It’s a nice break from shooting, though still tough if your timing’s off. And if you like the big numbers, Overpowered is the monster grind – rack up 1,000,000 total Power in Endgame. This isn’t a one-evening job, it’s more like a long road trip.
 Then there’s Pest Control – simple in theory, but still a milestone. Beat Endgame’s final boss and that’s it. Only problem is, getting there intact can be just as hard as the fight itself. Before you face that, you might stumble into Undaunted. That’s surviving the horde of “Fears” in the Suppression mission. It’s wave after wave, and you’ll quickly learn what “running low on ammo” really means. The Campaign challenges alone could keep you busy for weeks, and with more to find in Multiplayer and Zombies, there’s plenty left to hunt. If grinding every last one of them sounds exhausting, you might be tempted to buy CoD BO7 Boosting instead – but where’s the fun in that?
