Paradox Junction

Overview

Paradox Junction is the third round-based Zombies map of Call of Duty: Black Ops 7, after Ashes of the Damned and Astra Malorum. It came out for free on March 11, 2026, with the Season 2 Reloaded update. It is the third Zombies map set in Nuketown, after Nuketown Zombies and Alpha Omega. The mission briefing: “Killing time was never this much fun! Play gruesome games with the creepy Twins, destroy the Dark Heart and escape the warden’s temporal prison!”

The map holds a Nuketown both before and just after the detonation of a nuclear bomb, which shifts back and forth without end. The playable area reaches past the usual Cul-de-Sac into a larger part of the neighbourhood, down Trinity Ave., but adds no new interior. With the wall jumps of Omnimovement, roofs that were out of reach, such as those of the School Bus and the truck, can now be climbed. The map also has a Survival version, Nuked, set in the burnt town alone.

Welcome to Nuketown

Nikolai and Richtofen fight in front of the sign at the entrance of the town.

Characters

The players are the eight members of the crew: Weaver, Grey, Carver and Maya of the former Requiem, and the Dark Aether versions of Dempsey, Nikolai, Takeo and Richtofen. They land in Nuketown through the mushroom cloud, banished there by the Warden.

The Twins

Two girls who live in the doomed town and act as the announcers of the map, one alive, the other a rotting zombie. They hold the split memories of Samantha Maxis, and help the crew in exchange for their own way out.

The Warden

The ruler of this part of the Dark Aether, who sends the crew to the loop for freeing two of his Shadowsmiths. The intel of the map shows who he was: Jack McGregor, a Confederate soldier wanted dead or alive for $5,000.

T

The Entity

The woman the Warden keeps in a cage and drains of her life force. In the opening cinematic she tells him that the Dark Aether cannot be fixed.

S

Strauss and Peck

Heard on the radio logs of the map, looking from the real world for a way to reach the crew.

Enemies

Rad-Hounds

New on this map: radioactive dogs that run faster than a sprinting player, come in larger numbers than the old hounds, and explode on death into a pool of radiation. They fill the special rounds, with radiation pools all over the town, and join normal rounds from the low teens. Each Rad-Hound round ends with the town switching era.

Mannequins

The old figures of Nuketown, here as props, as enemies and in the secrets of the map.

The Dark Heart

The boss of the main quest: a huge, human heart floating over the town, the thing that keeps the loop going.

Zombies, Armored Zombies, Heavy Zombies and Doppelghasts complete the roster. Toxic Zombies only come with a Relic trial and the Agarthan Device of Cursed. Burning tornadoes and CDC zombies recall the first Nuketown Zombies.

Perks

Each perk of Black Ops 7 costs from 2500 to 9000 Essence, more for each perk already bought. On this map the machines are random: only Quick Revive, against the back of the School Bus in Nuked Nuketown, and Der Wunderfizz, against the garage at the end of Trinity Ave. in the same era, always stand at the same place. The other machines share ten spots across the two eras, so some perks have no machine at all in a given game.

Speed Cola

Faster reloads.

Stamin-Up

Faster movement.

Double Tap Root Beer

More damage per shot.

Deadshot Daiquiri

Easier critical hits.

Elemental Pop

Random Ammo Mod effects on shots.

PhD Flopper

Protection from one’s own explosions.

Death Perception

Enemies and items seen through walls; needed by the main quest.

Wisp Tea

A Wisp that kills zombies after enough damage; needed by the main quest.

Mule Kick

A third weapon.

Vulture Aid

Extra drops from enemies.

Weapons

Twelve weapons hang on the walls, six in each era, from 500 to 2000 Essence. The Mystery Box, at 950 Essence a spin, appears in both eras, and holds the wonder weapons of the map.

Blundergat

The wonder weapon, a four-barrelled shotgun back from Mob of the Dead and Blood of the Dead, from the Box or built from four parts found across the two eras. Its new upgrade, the Sundergat, fires charged shots and tears the souls out of what it kills.

Ray Gun, Ray Gun Mark II, Monkey Bomb and LT53 Kazimir

The other special weapons of the map.

Every wall weapon, its price, its era and its place

Time travel and Pack-a-Punch

After every Rad-Hound round, the town switches to the other era; the Temporal Conduit of the Cul-de-Sac does it on demand for 3000 Essence, or 1500 in solo. Every enemy on the map dies in the switch, and power-ups stay where they dropped. The Loot Cysts, the Rampage Inducer and Der Wunderfizz only exist in the nuked era. The Pack-a-Punch Machine floats over Trinity Ave., held by four Space-Time Knots, behind a truck that has to be driven away in the past.

Two eras

Weaver, Dempsey, Takeo and Maya under the mushroom cloud that hangs over the town for ever.

Loot Cysts

Growths on the walls of the nuked town that burst with Salvage, equipment and weapons once fed enough souls.

Electro-Shock Defenses

The trap of the map, over the garage doors of the two houses.

Trivia

• The game files call the map zm_sat_mantis, and the Blundergat ww_mantis.
• Some of the developers of Paradox Junction also made Nuketown Zombies, according to Treyarch.
• Treyarch chose the Blundergat because a shotgun suits a small map, and for its “power of souls”.
• The round music of the past reworks the music of Alpha Omega, and one jingle carries Samantha’s Lullaby.
• In the nuked era, zombies wander outside the map; they never come in, and shot, they vanish without giving points.
• Chalk drawings around the town show Citadelle des Morts, Reckoning and Astra Malorum.
• The map holds 18 pieces of intel: 10 audio logs, 3 documents and 5 artifacts.
