Paradox Junction in Black Ops 7 Zombies is the sort of map that punishes autopilot. One minute you're cruising, the next you've accidentally triggered something that turns the whole round into a fire drill. If you're trying to unlock the Summoning Key Relic (the one that makes zombies pop on death), plan ahead—especially if you're also warming up, testing builds, or even looking to buy CoD BO7 Bot Lobbies so you can practise routes without the usual headache. You can start the sequence right away, but you can't really rush the later steps.



Step 1: The chimney toss
Spawn in and look around the starting hub for the big chimney. This part's quick, but it's easy to mess up if you panic. Cook a normal frag for a moment, then drop it straight down the top of the chimney. Don't try anything fancy—just a clean throw. If you hit it, the game spits out a dog collar onto the dirt nearby. Pick it up and keep it safe, because it's one of the two items you'll need later.



Step 2: Brain Rot and the garden dig
Now you're playing the long game. Keep moving through rounds until you can get the Brain Rot ammo mod. You'll also need access to the pre-nuke version of Nuketown. Once you're there, head to the back garden of the yellow house. The trick is you can't force it with raw damage—you need a hellhound to flip. Infect a hellhound with Brain Rot so it turns friendly, then kite it into that yellow-house garden and hold the area. After a few seconds it'll start digging, and it'll pull up a tennis ball. Walk up close and grab the ball right out of its mouth before it wanders off or gets itself killed.



Step 3: Round 40, the down, and the grave
This is where most runs die, because people do it "kinda prepared" instead of actually prepared. Make it to round 40 and make sure you've got a Tier 1 Curse active. Go to the back garden of the green building and let the horde down you there on purpose. Seriously—don't even attempt this without a Self-Revive or the Equivalent Exchange effect from Quick Revive, because you need to stand back up after. The moment you go down, a gravestone spawns behind you. While you're bleeding out, interact with it and place both quest items: the dog collar first, then the tennis ball. If you hear Mr. Peeks laughing, you did it right.



Step 4: The portal fight and staying alive
Get yourself revived, then head to the side of the yellow building in the non-nuked timeline. A glowing portal should be there, and stepping in throws you into the Sinister Trial: a timed room with five waves and armored HVTs that soak up damage at round 40+. This is where you stop being "clever" and start being efficient. A Tier 4 Pack-a-Punched wonder weapon (Ray Gun works great) makes the timer manageable, and a War Machine can save a run when the room gets crowded. If you've got an Insta-Kill, pop it right as you spawn in and chain kills fast.
