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. According to Doctor Henry, its purpose was to use less power and therefore last longer.

Locations

 * The Stealth Boy Mark II prototype cannot be acquired in the game itself. Not even by killing Lily while she is wearing it.
