The First Room

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.
A GobbleGum machine
Next to a burning bed of the starting area, in the world record. The rule of this board: “Play with only Classic GobbleGums.”
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.”
