This place is crawling with Super Mutants so you have to be cautious and make the necessary preparations. This is part of the Children of Atom quest “Ablution”. There’s a small trapper base west of the factory built from container vans. It has some valuable aluminum cans, a toolbox, a bed, and a cooking station.
The location has three areas: The corporate HQ, the ground exterior (including the parking), upper exterior (rooftop area), and the factory building itself. The exterior area doesn’t have much to offer, except a handful of lootable containers.

In the second floor, there’s a Vim Refresh and Vim Captain’s Blend on the fridge. In the office area, there's an advanced wall safe in one of the cubicles, with the broken floor. There's another Vim Captain’s Blend in Madison’s cubicle, with an Expert safe, and Novice terminal. You can use the terminal to open the safe.
Novice Marketing terminal in the meeting room. The door to the Vim CEO room has an advanced lock. On his desk, his terminal is advanced-locked too but the password holotape is found beside the terminal. There’s a Vim Captain’s Blend on the beverage shelf as well.
There are more super mutants in the rooftop, including a suicider. In the Vim R&D room, there’s a chem station, and a terminal where you can download the Vim Recipe.
In the upper room to the NW, you’ll find a power armor station with a red Vim T-51 power armor with fusion core. In the same room, there’s a Vim Ambassador terminal where you can get the Vim Paint Job schematics.
In the upper middle room of the packaging area, there’s the brewing terminal with protectron control. Head north to find the taste testing area. Open the door to the NW of the room to find an unlocked safe with several ammo inside.
In the flooded ground level of the packaging area, there’s an advanced terminal that be used to open the dock doors. The dock contains a super mutant Behemoth named Grun. Open it only when you’re willing and capable of facing a behemoth. After defeating it, enter the dock and loot the red steamer trunk.
In the brewing area, you can access the Vim Mixing Terminal to open the nearby security door containing several containers. You’ll find the pump regulator needed for the quest “Ablution” on the table to the SW of the upper rooms. There’s an armor workbench, red industrial trunks, and more lootable containers in the immediate area as well.
On the ground floor of the brewing/mixing room to the southeast, there’s a novice terminal that will unlock the security door. Take the elevator and go downstairs. Approach the set of machines and you’ll hear a message from “Kye 1.1”. Speak to the intercom and speak with the AI. You’ll have the chance to convince him to open up or alternatively, you can bring Nick Valentine since he’s a prototype synth, one of the approved users to enter the containment area. Either way, once you convinced Kye to open up, you’ll be able to access the red steamer trunk and the unique shotgun called December’s Child.
