Walkthrough for The Chimerist's Last Experiment quest in The Outer Worlds. Learn how to start the quest, find Dr. Chartrand in Byzantium, and complete the mission.

Walkthrough
  1. 1
    After completing The Ice Palace, return to Lilya Hagen on board the Groundbreaker.
  2. 2
    Lilya will reveal her belief that aliens are responsible for the experiments found on Monarch and HRS-1084. She will task you with traveling to Byzantium to kill Dr. Chartrand, whom she suspects of collaborating with these aliens.
  3. 3
    Travel to Byzantium and proceed to the Estates District. Enter the house located northwest of the stairs leading to the Acropolis District.
  4. 4
    Use the Byzantium Estate Key provided by Lilya Hagen to gain entry.
  5. 5
    Inside the house, you can loot the area. Then, head into the southeastern room and use the terminal.
  6. 6
    Select the options _[Laboratory Access]_ and _[Unseal Entrance]_ on the terminal to open an elevator. You can also read logs that may support Lilya's theory.
  7. 7
    Exit the southeastern room and return to the central chamber. Head east to find newly unlocked doors leading to an elevator.
  8. 8
    Ride the elevator down and proceed through the doors to the west to find Dr. Eva Chartrand.
  9. 9
    You can choose to _[Attack]_ at any point during the conversation with Dr. Chartrand.
Tips
