Hazardous Material

Hazardous Material is a miscellaneous quest in Fallout 4.

Detailed walkthrough
Fred Allen will ask the player character to retrieve a HalluciGen gas canister from HalluciGen, Inc. The building is inhabited by Gunners and the gas canister is to be found in the basement. The Sole Survivor can persuade Fred to give more than the original 200 caps for the work, the payment amount can be raised to 250, 300 or with an intimidation, 400 caps.

Bugs
After retrieving the gas canister, the quest marker may be fixed on the player in the Pip-Boy map and invisible on the compass, and Fred will not have the relevant dialog choice in order to complete the quest. This can be circumvented by using the console command:. The player will still receive the correct amount of XP and caps after doing so.
