HalluciGen, Inc.

HalluciGen, Inc. is a location in the Commonwealth in 2287.

Layout
When the Sole Survivor first encounters the facility, a chemical leak causes all the NPCs to attack one another. Towards the end, there is a decontamination chamber that cures radiation poisoning.

Due to collapsed floors, the building's layout can be confusing. The entryway's reception area appears to open onto the second floor.

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

At some point, one can ascend into a corridor with several doors, which are opened by buttons. There are Gunners fighting behind each of them. Alternative to direct combat, the player can jump to the balcony with a staircase. This leads upstairs to a room, which will greet the player character with an announcement and invite them to test some "products." Pressing the various buttons in this room will emit poisonous gases to the rooms downstairs housing the Gunners. A terminal in this room reveals that the rooms below were actually used to demonstrate the products to VIPs, after which the rooms should be "cleared of test subjects, blood, fluids."

Behind the building is an exterior room with a green Gun Shop sign, inside which is a power armor station, a chemistry station, and a weapons workbench.

Entrance area

 * Two Help wanted! notes – On the entrance reception desk.
 * Five drugged water cartons in the entrance room: one on the small table immediately to the right after entering the building from the main entrance; four more behind the reception desk.
 * Day Tripper in the toilet tank after passing through locker/shower room.
 * Tesla Science Magazine issue #7 – Entrance level, northeast corner of the building, after ascending via a collapsed section of roofing. This is the room with the research terminal controlling a HalluciGen Suppressor prototype device.
 * Note from Eric – On a desk beside the accounting terminal on the second level.

Testing chambers

 * Two drugged water cartons in a testing room with two Gunners locked in.

Basement

 * HalluciGen master password – Can be obtained from the mainframe access terminal, giving access to the lab access terminal, decontamination terminal, research terminal and the CEO's terminal.
 * Nine HalluciGen gas canisters – All located in the same room as the Gunner commander. One unit is needed for the miscellaneous quest Hazardous Material given by Fred Allen in Goodneighbor, and some people report that it does not spawn until his quest is initiated. This room is reachable from the interior by a terminal with an expert lock. Alternatively, the room can be accessed directly from the Commonwealth through a back door, north of the building, with a master lock, bypassing most combat and chemical exposure.
 * 14 ruptured HalluciGen gas canisters – All located in the same room as the Gunner commander.
 * Stealth Boy – In an open safe in the same room as the Gunner commander.
 * HalluciGen mission brief and Gunner's note – On the Gunner commander.
 * Nuka-Cola Quantum – In the same room as the Gunner commander.
 * HalluciGen key – In a steamer trunk near the north exit to Esplanade; another copy is on the Gunner commander.

Behind the scenes
The effects of the gas seen in the game are similar to those of the real-life 3-quinuclidinyl benzilate gas, tested by the U.S. military.
