The First Room

On ZFRR, the First Room of Lighthouse is the open ground of Beacon Island: the rocks, paths and walls around the foot of the lighthouse, from the spawn on the south side of the island. The way in is a linked door: one purchase opens both the fishing shed and the inside of the lighthouse. Kept closed, it leaves the team outdoors, in the snow, below the tower. Like on every map of Black Ops 7, each player starts with a weapon of their own loadout, and with 500 Essence.
The prompt of the door reads 2,750 Essence. Behind it are the ground floor of the lighthouse, with the Armor Vest on the wall and a barrel of fishing rods, the spiral staircase, and the Pack-a-Punch Machine at the very top. Der Wunderfizz stands outside, next to the entrance of the fishing shed closest to the spawn, according to the wiki; no source says outright that it can be used with the door closed, nor whether the Mystery Box can be reached without the door.

XM325
2,000 Essence, Uncommon, its chalk outline drawn on a rock on Beacon Island, a few steps from the spawn. The other wall weapon, the M10 Breacher, is inside the lighthouse.

The linked door
2,750 Essence, read on the prompt at the foot of the lighthouse. Bought once, it opens the fishing shed and the lighthouse together.
Rampage Inducer
At the spawn, next to the FlaK 88 according to the wiki. It makes the zombies spawn and run faster.
Der Wunderfizz
The only source of perks on the map, outside the fishing shed. On Survival maps it is in place from the start of the match.
T.E.D.D. Tasks
The solo world record takes them on outside, doors closed, from the first rounds.
Out of reach
The Pack-a-Punch at the top of the lighthouse, the M10 Breacher, the Armor Vest and the barrel of fishing rods inside it, and the fishing shed.
The Lighthouse leaderboard keeps two categories, each with boards for solo and for two, three and four players. No GobbleGums is the reference; With GobbleGums counts in the player ratings with a lower difficulty. How a round of Black Ops 7 is built, and why it can go so high, is explained in Black Ops 7: Rounds. The rules:
Doors closed
Reach the highest round you can without opening doors, and play every round in full.
No GobbleGums
No gum is used, neither from the pack nor from the machine, and none is broken down for Essence. Keeping the three Whimsical gums in the pack is recommended: one used by mistake does not void the run.
With GobbleGums
On that board gums are allowed, and so is breaking them for points; a gum that has run out of time is not.
No glitch
Glitches and exploits are not allowed, and neither is saving and quitting or crashing the game to void a down, a Dying Wish or a game over.
Latest patch
Every game is played on the most recent patch. The game is still updated, and a patch that changes its balance can lead to a board being reset.
Video
The whole game must be recorded, with every player’s point of view in co-op on the No GobbleGums board. A Twitch video must be saved as a highlight, since past broadcasts are not accepted; a YouTube video must be public or unlisted.
