The First Room

The library where the game starts, with empty bookshelves, the chalk outline of the Olympia on the red wall and a hole broken in the brick, Mob of the Dead BO3 Custom, Call of Duty Black Ops III Zombies

The picture above shows the library in the released map, filmed by Kunjora for his guide of December 2024: empty shelves, the chalk outline of the Olympia on the wall and holes broken in the brick. On ZFRR, the First Room of Mob of the Dead BO3 Custom is the starting area of the prison: the players appear by the library of the cell block, the place the guides call spawn. It is also where the remaster began: copforthat says the spawn room was the first thing rebuilt, in August 2023, before the rest of the cell block and the cafeteria.

The solo world record, SlowChezzBurger’s round 19, shows how a game goes there. It starts with the M1911, and the zombies climb in through holes broken in the brick walls, which the player rebuilds like windows. Later in the video the player holds an M14: no source read for this book says where it comes from or what it costs.

The library

The spawn of the guides. Kunjora places the Olympia wall weapon near spawn, and the Steam guide puts a whiskey bottle of the song Rusty Cage on the shelves to its right. No guide gives the price of the Olympia.

The holes in the walls

The zombies come in through holes in the brick, looking out on the bay. The world record shows the prompt to rebuild them as barriers.

The first Cerberus head

The first of the three heads of the Hell’s Retriever waits in the Broadway area, behind the door that opens from the library, Watchful Wolf says.

Brutus

The mini boss first comes on round 9, Watchful Wolf says, and comes back from time to time in later rounds. Both records of the board go past that round.

The Mob of the Dead BO3 Custom leaderboard ranks the highest rounds reached in the First Room, in solo and in two players. In November 2026 the records stand at round 19 in solo (SlowChezzBurger, April 4, 2025) and round 18 in two players (Fxi and Ekzx, February 8, 2025). Mob of the Dead BO3 Custom is a custom map: it is listed with the Black Ops III custom maps, apart from the Black Ops II original, which has its own book, Mob of the Dead. The rules:

Doors closed

“Reach the highest round you can without opening any doors or barriers.” “Every round must be played in full.”

GobbleGums

“Play with only Classic GobbleGums.”

No glitch

“Glitches or Exploits are NOT ALLOWED.”

Video

“Full gameplay is required.” “Twitch: Make sure your footage is highlighted as past broadcasts will not be accepted.” “YouTube: Make sure your video is public or unlisted.”

Overview

Mob of the Dead is a Black Ops III remaster of the Black Ops II Zombies map, made by copforthat (Sean) and released for free on the Steam Workshop on November 29, 2024. Its Workshop page presents it as the escape from Alcatraz Prison, with Chazz Palminteri, Joe Pantoliano, Michael Madsen and Ray Liotta, “one of zombies most iconic experiences”, and thanks everyone who tested the beta. It also warns that its screenshots may be outdated.

copforthat tells the story in the video “How I Remastered Mob of the Dead”. The map began in August 2023 as lighting practice, next to another project: first the spawn room, then the cell block and the cafeteria, and by the end of that month the whole prison block. After a break, the whole map was blocked out with simple shapes so that doors and windows could be scripted early, and the gondola was the first feature, because it made play tests faster. Another modder, who was making a version of the map at the same time and had already ported the Blundergat and was working on the Hell’s Retriever, then joined the project. The public beta went live on June 17, 2024, and the map came out after about a year and a half of work.

Workshop credits: copforthat (project lead), tupivere_ (scripting, weapon ports, artwork), dobby (scripting, weapon ports), Xela (weapon ports), Hybs (mapping, Pack-a-Punch camos) and Rayjiun (effects), with robit for the muzzle flashes, GCP for the Brutus script, and Booris and Kingslayer Kyle for assets and zombies taken from Blood of the Dead. What changes from Black Ops II, according to the creator, the change notes and the guides of the remaster:

GobbleGums

The remaster allows them, the Steam guide notes among the differences with Black Ops II.

A solo Easter egg

The main quest is kept exactly as it was, but it can be finished alone: a bot plays Weasel in the final fight.

The Magmagat

A third form of the Blundergat, tempered in a fireplace and forged in the power room, as in Blood of the Dead.

Stamin-Up

A perk the original map did not have, hidden behind a boarded door of the infirmary.

Hide and Seek

A Samantha doll side quest that the Steam guide lists among the additions.

The real bridge

The Golden Gate Bridge seen in the distance is the one the plane lands on, so players left at the prison can watch their friends on it.

The Hell’s Redeemer

Its quest no longer needs round 10 or later, a requirement copforthat removed after players kept reporting the step as bugged.

The tower trap

It barely did anything in the original, copforthat says: it now deals more damage and fires faster. The acid and fan traps are kept as they were.

Brutus on the bridge

His script was modified so that he spawns on the bridge from time to time and can lock the Mystery Box and the traps.

Small touches

The Shiv replaces the knife of Black Ops III, the HUD is modelled on the one of Shadows of Evil, with a custom Max Ammo icon, and the characters talk to each other at key moments, with four players only.

Characters

The four inmates are played, as the Workshop page says, by Chazz Palminteri, Joe Pantoliano, Michael Madsen and Ray Liotta. The release version gave the mobsters new textures for their first-person arms, and the making-of video credits the third-person character models and the artwork seen in game to the modder who joined the project with the Blundergat. With four players, the characters now talk to each other at key moments of the game. The guides only name one of them, Weasel, who is at the heart of the final fight of the main quest.

Enemies

Zombies

They climb in through windows and holes in the walls. A ghost in Afterlife can zap them to teleport them away, Watchful Wolf explains. The Workshop credits Kingslayer Kyle for zombies taken from Blood of the Dead.

Brutus

The mini boss of the map. He first spawns on round 9, then at times in later rounds and repeatedly while players are on the bridge. If he reaches a perk machine, the Box or a trap he locks it, and players must pay to unlock it. copforthat built him on a script by GCP, and admits that some players found him far too easy and others far too hard.

Weasel

In the solo finale of the main quest, a bot plays Weasel against the player. It was made much easier to kill on November 30, 2024.

Afterlife

The ghost form of the original is, in copforthat’s words, the backbone of the map. Each player can become a ghost, either on going down or at the Afterlife boxes on the walls, and zap panels to power perk machines, open gates, lower the Warden’s Key and start the gondola. A meter runs down meanwhile: the player must get back to the body, or be revived, before it runs out. The system was ported by dobby, and the release version increased the Afterlife jump height.

The panels

Electric panels, often right next to what they power, that only a ghost can zap.

Perks

Every machine stays dark until a ghost zaps the panel next to it. Kunjora warns that the remaster has a four-perk limit. No source gives the price of the perks. Stamin-Up, new to this version, opens only to the Magmagat.

Speed Cola

In the warden’s office, next to the fireplace of the Magmagat quest.

Electric Cherry, Juggernog

Upstairs in the cell block for the first, near the bottom of the gondola for the second.

Deadshot Daiquiri, Double Tap Root Beer

In the infirmary for the first, on the way down from the warden’s office into the Citadel tunnels for the second, according to the Steam guide.

Stamin-Up

Behind a boarded door of the infirmary that only the Magmagat can burn.

Weapons

Every game starts with the M1911. The wall weapons come from Black Ops II, rebuilt with the remastered models of Xela, from the Olympia near spawn to the Remington of the Citadel tunnels. The Mystery Box holds the Blundergat, and the guides are seen holding the Ray Gun and its upgraded form. The tomahawk of the map, the Hell’s Retriever, comes from three Cerberus heads and upgrades into the Hell’s Redeemer; the Spoon and the Golden Spork are the melee weapons, and the Zombie Shield is built from three parts.

Wonder weapons

The Blundergat, with its model and animations ported from Black Ops 4, comes out of the Box or for free after hitting five skulls with the Hell’s Retriever. The Acid Gat Kit turns it into the Acidgat, as in Black Ops II, and the remaster adds the Magmagat: the weapon is tempered in the fireplace of the warden’s office, carried hot down to the power room and forged there.

The Magmagat

Kunjora’s advice: shoot it at the floor and let the zombies run into the flames.

Pack-a-Punch

As in the original, the Pack-a-Punch stands on the Golden Gate Bridge. The Warden’s Key opens the way to five plane parts (the uniforms, the rigging, the engine, the fuel tank and the valves), and the plane built on the roof flies there. Electric chairs bring the players back to the island, and the plane can be refuelled with gas canisters for the next trip.

The machine

At the end of the bridge, with Pack-a-Punch camos made by Hybs.

Easter egg

The main quest is the one of Black Ops II, which copforthat kept unchanged: three trips to the bridge with the Hell’s Retriever, the Spoon and a Blundergat, four prisoner numbers on the number pad of the Citadel tunnels, the guided tour of Alcatraz and a final fight on the bridge with two endings. The difference is that it can be finished solo, against a bot playing Weasel.

Secrets

The songs Rusty Cage and Where Are We Going, hidden power-ups in three cells, the Brutus voice line of code 115, the new Hide and Seek with Samantha’s dolls, and, according to the change notes, hidden questlines that the guides do not document yet.

Trivia

  • The map was meant to come out on December 5, 2024. About an hour after copforthat announced that date, Treyarch announced Citadelle des Morts for the same day, so the remaster was released a week early so as not to be overshadowed.
  • A few weeks after the release, copforthat noticed that a Black Ops II themed loading screen among the Prestige 6 rewards of Black Ops 6 looked strikingly like a picture of this remaster. In April 2025 copforthat said Treyarch had not mentioned it.
  • copforthat recalls an earlier attempt to remaster the map, by Shifty Gamer, made a few years after the mod tools came out, as one of the projects that inspired the Call of the Dead remaster.
  • Between the two parts of the project, copforthat scripted for Hybs’s survival map of the bridge a system in which the plane of Mob of the Dead drops a random perk every few rounds.
  • The plane teleports in the middle of its flight, hidden by the fog. The hardest part of the Cerberus heads, copforthat says, was lining up the animation so that each zombie lands in the mouth of the dog.
  • Treyarch went back to Alcatraz at the launch of Black Ops 4 with Blood of the Dead, which, copforthat says, shared only its location with the original map: one reason the community still wanted the original experience remastered.
