Black Ops 7 Nuked Survival Event

The Nuked Survival event is a 7-day limited-time grind exclusive to Black Ops 7 Zombies. Complete all six challenges on the Nuked Survival map to earn the Chronology universal mastery camo. Each individual challenge also drops a cosmetic reward, so you won't walk away completely empty-handed when Treyarch inevitably breaks your spirit.

The event runs June 4–11, 2026. After that, the Chronology camo is gone. Forever. Hopefully that motivates you more than the camo itself does.

5,000 Wallbuy Kills

Five thousand kills. With a wall-buy weapon. On one map. Treyarch is testing your loyalty and your free time simultaneously. The Black Ops 7 Zombies wallbuy weapon you want is the MXR near the Pack-a-Punch, or the M8 if you refuse to spend a single door coin. There's also a pistol right at spawn for the truly frugal.

• Use the Wall Power GobbleGum immediately. It makes the wallbuy usable for the entire run instead of a wet paper firearm.
• Pack-a-Punch the weapon as early as possible. 5,000 kills with an unupgraded gun at round 40 is how people develop contempt for hobbies.
• You will be using this gun for most of the run anyway. It doubles as your primary. This challenge is ambient damage.

25 TEDD Tasks

TEDD Tasks begin spawning around round four, which means you have no excuse not to start working on them immediately. They come in various flavors: some reasonable, some insulting. The "stand still and get kills" variant was clearly designed by someone who has never heard of stick drift.

You do not need legendary TEDD Task completion for this challenge to count. Blue rarity is enough if the task risks getting you killed at higher rounds. Survive first. Cosmetics second. Ego never.

• Legendary completions give perks, wonder weapons, and better items. Worth attempting early when the round count won't murder you.
• At high rounds, any task requiring you to stand in a fixed zone becomes a suicide mission. Complete to blue and walk away.
• This challenge overlaps heavily with Challenge 6. You'll knock both out without trying.

Rapid Rad-Hound Kills ×20

Rad-Hounds appear exclusively during special rounds Nuked Survival mode, which trigger randomly between rounds five and seven and grow more frequent later. They are not on a schedule. Treyarch did not feel the need to give you control over this.

• In early rounds, train them. Let at least five gather before firing. You need five rapid kills per instance to register progress.
• Past round 20, ten to fifteen spawn simultaneously. No training needed. Just shoot.
• If you get five kills and then five more back-to-back, it may count as two progressions. It may not. Assume it won't and pause briefly between bursts.

Blundergat: 10 Kills Without Reloading ×15

This Is The Bad One The Blundergat does not build in Nuked Survival. There is no crafting table. There is no Easter egg step. It comes from the Mystery Box: rarely: or from a Legendary TEDD Task completion: also rarely. You will open that box a hundred times and get Ray Guns. Congratulations on your collection.

Once you have it, the task is getting 10 kills without reloading fifteen separate times. The Blundergat wonder weapon BO7 cannot be Pack-a-Punched on this map, which makes later rounds increasingly hostile to this objective. You need to train zombies into a dense cluster and unload into the crowd. Patience is mandatory. Self-respect is optional.

Legitimate Ways to Get 10 Kills Without Reloading

• Equip Frenzied Guard with the Frenzy Fire Augment. This directly assists the no-reload challenge by reducing reload reliance.
• Use Stock Option GobbleGum or Free Fire GobbleGum. Free Fire literally eliminates ammo consumption temporarily.
• Do not attempt this at high rounds without a plan. The Blundergat without upgrades is a liability after round 30.
• Stay in tight corridors. Force zombie density before firing.

Round 20 With No Perk Machine

This challenge sounds catastrophic. It is not. The restriction is specifically on perk machine round 20 no perks purchases, not on holding perks. GobbleGums that grant perks are fully valid. Legendary TEDD Task completions that award perks are fully valid. You can run Juggernog, Speed Cola, and every perk in the game: as long as a machine didn't sell them to you.

• Ether Shroud is your escape button when Jug is absent. Use it when cornered.
• Upgrade armor plates aggressively. Tier 3 armor compensates for missing perks when zombies start hitting like freight trains.
• You don't need to complete round 20. The moment the game transitions from round 19 to 20, the challenge triggers. You can exfil immediately. You won't, but you can.
• Spend money on the Mystery Box and armor. Not machines. Never machines.

25 Special Rounds

This one completes itself. Play the game, complete special rounds zombies as they appear, and the counter moves. The Rad-Hound rounds you're farming for Challenge 3 are special rounds. The overlap is significant. This challenge exists primarily to make the total look intimidating.
