HalluciGen, Inc.

HalluciGen Inc. is a location in the Commonwealth in Fallout 4.

Layout
When you first encounter the facility, there has been a chemical leak and all the NPCs are attacking one another. Towards the end there is a decontamination chamber that cures radiation poisoning.

The layout of the building can lead to some confusion in determining which level you are on due to the significant amount of collapsed floors in the building. It would appear that the reception area after entering the main front door opens onto the second floor.

To access the third floor you may need to walk into a wall painting blocking the doorway to the staircase leading to it to nudge it out of the way. Further, two inactive protectrons may block your way into the first room on the third floor requiring their destruction.

Notable loot

 * Combat armor pieces - On body on gunner commander after killing him (commander uses stealth boy).
 * Nuka Cola Quantum - Found in the same room as the gunner commander just before the rear door that is locked by a key found on the commander.
 * Minigun - Second floor, found after traversing through most of the building from the front door. In the room just before and the right of the decontamination corridor and associated control room.
 * Fusion core - Located on the second level in the room where you first see the Gunner Conscript. Found between an upturned filing cabinet and desk on the floor.
 * Tesla Science Magazine - Found on the second floor after ascending via a collapsed section of roofing. It is found in the first room after the hallway on a cabinet in the southwest corner.
 * Night-vision hardened pipe revolver sniper rifle. - Found in one of the rooms with blue "generator" thingy and gunner conscript, behind a shelf on the ground (You might need to jump on to see it.)
