Every weapon of Farm in Black Ops 7 Zombies: the Echo 12, the Ryden 45K, the Peacekeeper Mk1 and the MK.78 with their prices, the Mystery Box, Chompy and the Ray Gun, the power of the barn, the Pack-a-Punch, the Arsenal and the traps.
The walls of Farm sell four weapons, all at Uncommon rarity. A weapon bought on the wall is raised to a better rarity at the Arsenal, with Salvage.

Mystery Box
The Box stands in the shed and moves to the cellar. Fandom lists more than sixty weapons inside: the launch arsenal of Black Ops 7, the weapons added season after season, up to the TR51 Para, the VMP and the Roc 20mm of the update of October 15, 2026, and three special weapons.
Ray Gun
From the Box, or always from Chompy for ten Monkey Bombs.
Ray Gun Mark II
From the Box.
Necrofluid Gauntlet
The wonder weapon of Ashes of the Damned, built there in the main quest. On Farm it only comes from the Box.

Chompy
Chompy is a small trash can along the fence between the farmhouse and the barn. Hit it with a melee attack and its lid opens on what looks like a black hole: it swallows a weapon or a piece of equipment and gives back Salvage, more for a better rarity and Pack-a-Punch level, and sometimes equipment or a wonder weapon. Ten Monkey Bombs always buy a Ray Gun. It does not take the melee weapon or the Necrofluid Gauntlet, and on Survival maps it stays awake, except during a Special Round or an Exfil.

Power and Pack-a-Punch
The farm starts without power. A Power Pump covered in growths stands in the yard, in front of the grain silo: destroy its growths within thirty seconds while purple-eyed zombies attack, then flip the Power Switch on the upper floor of the barn. The power wakes the Pack-a-Punch Machine, set in place on the upper floor of the barn on the other side of the switch. The Arsenal, which raises the rarity of a weapon with Salvage, is in the cellar.
Crafting Table
In the barn, right in front of the main door.
Saw Blade Trap
To the left of the main door of the barn. Paid in Essence, it plays a haunting tune that draws the zombies to its saw blades.
Mystery Box
In the shed, with the Armor Vest; its other spot is in the cellar.
GobbleGum Machine and Rampage Inducer
On the porch of the farmhouse. The Rampage Inducer makes the zombies spawn and run faster.
Treyarch’s blog explains the choice: in Ashes of the Damned the Pack-a-Punch is clamped to Ol’ Tessie and the farm has no Wunderfizz, so for Survival both were dropped into the farm, the Pack-a-Punch back in a fixed place.
None of this is in reach doors closed: on ZFRR, the First Room of Farm is the yard, with the Echo 12, Chompy, the Saw Blade Trap and the GobbleGum Machine. The main page describes it.
