Summoning Key Relic Tutorial - Black Ops 7 Zombies
Zombies explode when killed, and the blast can damage you if you stay too close to the body.
Map: Paradox Junction | Tier: Sinister | Difficulty: Medium
Cursed requirement: Cursed Mode Tier 1, 2, or 3 required.
Portal: Yellow House, southwest outside wall.
Save note: Unsafe after collecting the dog collar.
Unlock steps
- In Pre-Nuke Nuketown, throw a grenade into the broken chimney near the clock and pick up the dog collar that drops.
- In the Yellow House backyard on Pre-Nuke Nuketown, use Brain Rot to turn a Rad Hound zombie.
- Let the turned Rad Hound zombie dig up the ball, then collect the ball.
- On round 40 or later, down yourself in the garden behind the Green House so the grave rises.
- Interact with the grave to place the dog collar and ball.
- Enter the Yellow House portal after the grave interaction opens it.
Trial rules and prep
Each wave has a timer, and every zombie must die before time expires. Waves 1, 3, and 4 build progress, while waves 2 and 5 can mix Rad Hound zombies with Doppelghast HVTs.
- Equivalent Exchange or Aftertaste can protect the intentional down and keep the setup from costing the run.
- A low-rarity Brain Rot pistol is less likely to kill the Rad Hound zombie before it digs up the ball.
- Ray Gun, Kazimirs, Free Throw, and War Machine pressure are excellent for timed clears.
- Keep distance after zombie kills during both setup and trial, because the relic effect turns close-range cleanup into chip damage.
