— Chase

Chase is a character on the Island in 2287.


Chase is a member of Acadia. She was once a courser, working for the Institute, until she met DiMA and was convinced of his mission. She cut all ties with the Institute and is now helping the escaped synths travel safely to Acadia.

  • Chase is the first and, so far, only female courser encountered in the game.
  • Given that a courser chip is an integral part of every courser that apparently cannot be removed without killing them, but also allows the Institute to pinpoint the courser's location in order to relay them back underground, it is unclear why they did not do exactly that when Chase went rogue.
  • Unlike many other synths in Fallout 4, Chase's name is not a 4 digit alphanumeric code. This is likely symbolic of Acadia's status as a safe haven for synths who wish to start a new life, similar to the Railroad in the Commonwealth.
  • Chase is the second known Courser to go rogue, the first one being Harkness.


Chase appears only in the Fallout 4 add-on Far Harbor.
