You’ve probably seen the screenshots. That shimmering, reality-bending Nebula camo plastered all over social media. It looks incredible, right? But if you’re staring at a base-level XM4 and wondering how on earth people are already sporting purple-and-green cosmic swirls, you aren't alone. The Black Ops 6 camo challenges Zombies players are currently tackling represent a massive shift in how Treyarch handles the long-term grind. It isn't just about mindlessly shooting undead in a corner anymore; the movement system and the sheer aggression of the Liberty Falls and Terminus maps have changed the math.
It’s a marathon. Honestly, it’s a bit of a headache if you don’t have a plan.

The core loop of the Black Ops 6 Zombies camo grind is built on three distinct tiers: Military Camos, Special Camos, and those coveted Mastery Camos. Unlike previous years where you could basically sleepwalk through the early stages, the Omnimovement system in BO6 means the zombies are faster and their pathing is more erratic. You can’t just sit on a catwalk and expect to hit 2,000 critical kills without getting swiped from a weird angle.
How the Military Camos Actually Work
Before you even see a sniff of the Mastery stuff, you’ve got the Military Camos. These are your bread and butter. For almost every weapon, the requirement is straightforward but tedious: Critical Kills. We’re talking about thousands of headshots.
In the past, people would just load up a map and aim high. In Black Ops 6, that's still the play, but the "Mustang and Sally" style explosive builds won't help you here. If you’re using explosives or elemental ammo mods like Brain Rot, those kills often won't count as "Critical." You need pure, lead-to-forehead contact. Most players hit a wall around the 1,500 mark because the scaling difficulty of the rounds makes it hard to maintain accuracy when Manglers are sprinting at your face.
The pacing is frantic. One second you're lining up a perfect train of zombies in the Liberty Falls bowling alley, and the next, a Vermin is leaping at your shins, ruining your aim. It's frustrating. You'll spend hours just to unlock the "Special" challenge slots, which is where the real personality of the grind starts to show up.
The Special Challenges: Where Things Get Weird
Once you finish the Military camos, you unlock two unique "Special" camo slots for that specific gun. This is where Treyarch gets creative—or annoying, depending on your patience.
For example, some SMGs require you to get kills while the weapon is Pack-a-Punched, while certain Sniper Rifles might ask for "Longshot" kills, which are notoriously difficult on the cramped, foggy docks of Terminus. You might find yourself needing to kill 10 zombies in a short window of time or taking down "Elite" enemies like the Abomination or the Amalgam.
- Pistols: Often require kills shortly after swapping weapons.
- Shotguns: Usually focus on point-blank kills or multi-kills.
- Launchers: These are a nightmare. You're looking at "Direct Hit" kills, which feels like trying to thread a needle with a sledgehammer.
One specific trick many high-level grinders use is the "Sentry Gun" strat—not for the kills themselves, but to herd zombies into a narrow lane so you can pick them off for your specific weapon requirements. If you aren't using the environment, you’re making it ten times harder on yourself.
Why Everyone Wants Mystic Gold and Opal
Let’s talk about the Mastery tiers. This is the real reason you’re reading this. In Black Ops 6, the progression goes: Mystic Gold, Opal, Afterlife, and finally, Nebula.
Mystic Gold is the first hurdle. To get this, you need to complete all Military and Special camos for a weapon, and then complete a specific Mastery challenge—usually getting a certain number of kills while the gun is Pack-a-Punched without dying. It sounds easy. It isn't. When a round 30 exfil starts falling apart and you're one kill away from the challenge, the pressure is genuine.
Opal is the next step up. This requires you to unlock Mystic Gold for a set number of weapons in a specific class. If you want Opal on your Assault Rifles, you better be prepared to max out every single AR in the game. The visual payoff is a white, pearlescent finish that looks cleaner than almost anything we saw in Modern Warfare III. It’s the "minimalist" flex.

The Road to Nebula
Then comes the heavy hitters. Afterlife and Nebula.
Afterlife has this glowing, ethereal blue pulse that looks like it was ripped straight out of Mob of the Dead. To get it, you need to have Opal unlocked across several weapon classes. It’s a massive time sink. We’re talking hundreds of hours of gameplay.
Nebula is the final boss of the Black Ops 6 camo challenges Zombies experience. It’s a reactive, animated camo that covers the entire weapon in a swirling galaxy of purple and green. It is, quite frankly, the best-looking Zombies camo Treyarch has ever produced. But the cost? You have to be a completionist. You have to touch every weapon, from the most powerful LMG to the most pathetic, slow-reloading secondary.
Mistakes You Are Probably Making
Most players fail because they don't manage their "Salvage" correctly. In Black Ops 6, your weapon rarity (Green, Blue, Purple, Orange) matters just as much as your Pack-a-Punch level. If you're trying to get critical kills on round 25 with a "Red" base-tier weapon, you're going to be shooting peas. You need to upgrade your weapon rarity at the Arsenal as soon as possible to keep your damage high enough for one-shot headshots.

Another big mistake? Ignoring the "Augments."
The new research system for Perks and Field Upgrades is vital. If you’re going for Sniper camos, you absolutely need the "Deadshot Daiquiri" augments that increase critical damage. Without them, the grind feels like a chore. With them, you’re a headshot machine.
Tactical Advice for the Faster Grind
If you want to speed this up, stop playing full matches to round 50. The most efficient way to farm camos is to play until round 20 or 25, then exfil or restart. Why? Because the "spawn rate" to "difficulty" ratio is best in those middle rounds. Once you hit the 30s, the super-sprinters and the constant barrage of Elites make it much harder to focus on specific challenge requirements.
Also, use the "Save Custom Mod" feature. You're going to be switching between weapons constantly. Having your optimal attachments—specifically ones that increase "Flinch Resistance" and "Recoil Control"—ready to go the second you pick up a wall-buy or hit the Mystery Box is a lifesaver.
Actionable Next Steps for Grinders
- Focus on one class at a time: Don't jump between an AR and a Melee weapon. Stay in the rhythm of a specific weapon type to master the muscle memory for headshots.
- Prioritize Deadshot Daiquiri: This is the single most important perk for Zombies camos. The auto-aim to the head (on controllers) and the critical damage boost are non-negotiable.
- Farm Liberty Falls for Headshots: The map is brighter and has flatter sightlines than Terminus, making it much easier to rack up the 2,000+ critical kills needed for the Military tiers.
- Save your GobbleGums: Don't waste "Perkaholic" or "Wall Power" on easy games. Save them for the weapons you hate using, like the slower snipers or launchers, to give yourself an immediate advantage.
- Track your progress manually: The in-game menus can be clunky mid-match. Know exactly how many "Elite" kills you need before you start the game so you don't waste time killing Manglers you don't need.
The grind for Nebula is designed to last the entire life cycle of the game. It’s not something you’re meant to finish in a weekend. Take it slow, enjoy the movement system, and remember that every headshot gets you a little bit closer to that cosmic glow.
