Jack (weapon)

Jack is a more powerful version of the Ripper.

Location
Jack can be found inside the Deathclaw Sanctuary on an Enclave Officer. The officer spawns alive, but unless you cleared out the deathclaws on an earlier visit, she won't be by the time you reach her. Refer to the map for the general area, but remember, since she spawns alive she may not be right where the map indicates. This weapon is not available until after the Enclave shows up in the storyline.

Trivia
