|The following is based on developer test content cut from Fallout 76.|
w00by is a character found in a test cell in Fallout 76.
w00by has nothing to say to the player character when interacted with. An exploit allowed access to the dev room (QASmoke test cell), it was later patched.
w00by appears in the game files of Fallout 76. He is in a test cell and is not used in-game.
