HalluciGen, Inc.

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

Layout
When the Sole Survivor first encounters 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 due to the amount of collapsed floors. It would appear that the reception area after entering the main front door opens 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 leading to it to nudge it out of the way. Further, two inactive protectrons may block the way into the first room on the third floor requiring their destruction.

The special grenade, HalluciGen gas grenade, can only be made when a HalluciGen gas canister is in the player character's inventory, i.e. it will not appear as a crafting option if the canisters are placed in the workbench or workshop inventory. The canisters are regarded as "junk".

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. Instead of opening the doors and simply killing them, a jump to the balcony with a staircase will lead upstairs where there's 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, where the gunners are. 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'.

Notable loot

 * Tesla Science Magazine issue #7 (+5% energy weapon critical damage) - 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.
 * Seven drugged water - Five 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. Two more in a locked room deeper in the facility, near the gunners locked in the "testing chambers".
 * Fusion core - Second level, in the room where the Gunner conscript is first seen, between an upturned filing cabinet and desk on the floor.
