|The following is based on developer test content cut from Fallout 3 and has not been confirmed by canon sources.|
MS14ArmorVoice (named MS14 Armor Voice Cell on the local map) is a test cell in the game files of Fallout 3.
Using similar architecture to the FFSceneRoachCell, it contains a concrete structure with a Mister Gutsy. It is related to the quest You Gotta Shoot 'Em in the Head.
The MS14 Armor Voice Cell appears in the game files of Fallout 3, but it is not considered canon because it is a test cell.
