Notes[]

Serum Z was previously placed at the West Tek research center, with the quest marker leading to its location in the research wing, which was accessed via terminal. The change in location to the RobCo Research Center has been reported since at least November 2022.[1] Given the changes to the West Tek research center with the Steel Reign update, it is possible the alteration occurred as a part of or after that update, though this has not been explicitly confirmed. This quest has suffered from multiple reports of bugs related to Serum Z before and after the location change (see below).

Bugs[]

  • PCPC The quest marker for Past Expiration may become bugged and will not direct the player to Serum Z's location.[2][verified]
  • Xbox OneXbox One Sofia's dialogue to accept Serum Z may become bugged and she will not be available to take the serum and complete the quest. This bug has been reported since Wastelanders's release and before the location change. Scrapping Sofia's ally workshop object may resolve the issue, as may dropping Serum Z from one's inventory, joining a different server, and re-retrieving the item.[3][4][verified]
