Find Hephaestus Research

You will be working for the Chemical Assault Unit during this mission, which ultimately leads to the demise of Free Drones in South Underrail.

Objectives

  • Captain Mareth sent you to find at least two cans of mutagen which is to be used against the Free Drones. He mentioned a facility that might have it, but doesn't know its location, other than it's in the cave system north of Rail Crossing.
  • Captain Mareth told you to find someone in Fort Apogee that will rig the mutagen cans to release the gas with a delay. Afterwards, you are to find the entrance to under-passage, just south of Rail Crossing and link up with CAU.

Walkthrough

Two parts, both in Lower Underrail.

There are two potential sources of Mutagen D5; Bunker and in the storage site at the Abandoned Waterways Facility. The bunker can be found in the caves north of Rail Crossing's metro station. This is the bunker entrance. Once you have found at least two intact Mutagen D5 canisters, return to Mareth in Fort Apogee.


At this point you must find someone to rig the mutagen canisters with a timer. Will the mechanic in Fort Apogee's dreadnought maintenance bay can do it. Once the mutagen canisters are rigged, head to the Free Drones under-passage base in Lower Underrail and rendezvous with the CAU. You can find it in the under-passages just south of Rail Crossing's entrance. Then simply follow the CAU team's orders. Save your game before doing so just in case.

If at any point player comes into contact with the Mutagen, they will turn into a mutant, starting Mutant Questline.

After everything is done, go back to Fort Apogee and talk to Mareth once again to finish the quest. You may also optionally reveal to him who rigged the containers.


Be sure to check back on Fraser some time after completing the job. Captain Mareth will have sent you a surprise gift: Chemical Assault Unit Armor.

After this quest you might sometimes run into the Free Drone Mutants random event so that you don't forget what you have done.
