Chasing the Nexus Horizon in Black Ops 7 can feel like you’ve signed up for a full‑time job, and you figure that out pretty quick once you start working through the mastery list. It’s not something you unlock by accident. The moment you dive in, especially if you’ve been warming up in a CoD BO7 Bot Lobby, you realise every mode throws its own wall in your face, and you’ve got to climb each one before the next even matters.

Multiplayer Mastery

MP is where most players begin, and it’s usually the one that feels the most familiar. The Singularity camo sounds simple until you start ticking things off and notice how many different weapon classes you still have half-finished. You need headshots, longshots, awkward challenge brackets, and the pace shifts constantly depending on the lobby you land in. People often try to brute‑force the whole list in one go, but that usually ends with them staring at a menu screen, exhausted. Short sessions and focused goals work way better.

Zombies Mastery

The Infestation grind is a different type of pain. The early stages feel great—you mow down hordes, level weapons fast, and challenges fall into place. Then the late-game ones show up and slow everything down. If you’re not used to managing zombie routes or stacking points efficiently, the mode starts pushing back pretty hard. Most players eventually settle into a rhythm: build a simple route, avoid any flashy risks, and let the numbers pile up.

Campaign and Co‑op Mastery

People tend to underestimate Genesis because they think Campaign challenges will be easier. They’re not really easier; they’re just different. Some of the objectives need you to replay missions in very specific ways, and it’s easy to miss a requirement and not notice until much later. This is the one mode where going slow actually saves time, because rushing usually means doing it twice.

Warzone Mastery

The Apocalypse camo is where most players hit their breaking point. BR challenges rely on positioning, timing, and a bit of luck. Going for kills early rarely helps. You need to survive long enough to stack multi‑kill moments near the end, and that means picking boring rotations sometimes. Players who stay calm and avoid ego‑chasing fights usually get this camo way sooner.

Pacing the Whole Grind

The smartest thing you can do is avoid juggling all four modes at once. Pick one, finish it, move on. A lot of players lose days repeating challenges they already completed simply because they didn’t track progress properly. Even a basic checklist helps you avoid wasting hours on stuff that doesn’t move you forward.

Once the dust settles and all four mastery paths are cleared, the Nexus Horizon drops onto your account without any ceremony, but there’s a real sense of victory when you equip it. It’s a universal camo, so you can throw it on literally anything across BO7 or Warzone, and everyone who sees it knows you earned it the hard way—whether you started from scratch or warmed up through a buy CoD BO7 Bot Lobby.
