Makeshift gas mask

The makeshift gas mask is an unused piece of equipment in Fallout 3 which would have been used in Vault 106.

Characteristics
According to the Fallout 3 Official Game Guide, wearing the helmet would have prevented the various hallucinations normally encountered in Vault 106. Although the helmet does exist within the game's files it is only partially functional, preventing the blue/purple tint from appearing over the player's vision but not the associated hallucinations.

Locations
Presumably, it would be found in Vault 106; however since it was never fully implemented, it is nowhere in the released game.

Bugs

 * The helmet suffers from a bug which adds the blue/purple tint to the player's vision when it is removed, even if the player is no longer in Vault 106. If removed from the player's inventory via console commands while worn, this bug will not occur.
