Stealth Boy Mark II Prototype

The Stealth Boy Mark II prototype is a world object in Fallout: New Vegas.

Background
The Stealth Boy Mark II prototype is an enhanced Stealth Boy, put through testing by the Enclave during the Great War.

You, as the player, never actually see the prototype itself. It is only seen used on Lily during the quest Guess Who I Saw Today.

The item cannot be acquired by the player.

Characteristics
It enables the user to go indefinitely invisible, does not factor in running, Pip-Boy light, or any other normal things that can render a Stealth Boy useless; in effect, you are invisible, for as long as you want, and nothing factors in to stealth. This Stealth Boy can be 'toggled' for use. There is only one Stealth Boy Mk II.

Locations

 * The Stealth Boy Mark II prototype cannot be acquired in the game itself.
