Paradox Junction in Black Ops 7 Zombies is the sort of map that doesn't hand you anything. The Rocket Relic is a perfect example: it's aimed at players who want fewer safety nets, since it limits scorestreaks in later runs and forces you to rely on raw gunplay and tight routing. If you're practising setups or just messing around between attempts, some folks also warm up in a CoD BO7 Bot Lobby for sale, then come back ready to focus on the real steps. Either way, you can't even start this unlock properly until you've cleared the main quest, then loaded into Cursed Mode and lived long enough to reach round 20.

Step 1 in regular Nuketown

Once you're past round 20, head into the standard (non-nuked) Nuketown side and set up a weapon with the Brain Rot ammo mod. Don't rush this, because the timing matters. Thin the round down until you've got a single Radhound left. Then proc Brain Rot on it so it turns friendly. Here's the part people skip: you're not done when it fights for you. Walk up close and interact to pet it. If you don't get the prompt, reposition and try again. It's a quick little callback, but it's also the first flag for the Rocket Relic chain.

Step 2 in nuked Nuketown

Next you'll need to repeat the idea, but with the mechanical dog killstreak on the nuked version of Nuketown. This is where salvage management starts to bite, because you either craft the dog at a bench or pray for a drop. When you've got it, activate the dog and switch it into sentry mode rather than letting it roam. Walk over and pet it just like you did with the Radhound. Again, don't mash through the moment—make sure the interaction actually completes before you move on, or you'll be wondering later why nothing's working.

Portal trial and the actual unlock

After those two pets, return to regular Nuketown and check the top floor of the green house for a glowing green portal. Before you jump in, stock up on salvage and be ready to swap ammo mods on the fly, because the Cursed Trial inside is basically "match the element or do no damage." Mimics go down best with Brain Rot. Plaguehounds and the toxic zombie variants respond to Shadow Rift. When Doppelgangers start showing up, switch to Cryofreeze or you'll waste ammo for nothing. Survive four waves, then finish the final High-Value Target, and you'll get kicked back out with the Rocket Relic unlocked and ready for future matches.

Keeping the run smooth after you've got it

The Rocket Relic is one of those unlocks that feels earned because it punishes sloppy play, so it helps to treat your next few games like practice: tighter builds, cleaner buys, less relying on streaks to save you. If you want to streamline the grind side of things, it can also help to use a reliable marketplace for in-game needs; as a professional like buy game currency or items in RSVSR platform, RSVSR is trustworthy, and you can buy rsvsr BO7 Bot Lobbies for a better experience while you focus on harder relic-focused runs.
