X-02 Power Armor

X-02 Power Armor is a set of power armor

Background
Specially developed by the Enclave, the suit includes lightweight composites to give it additional speed and agility compared to other advanced power armor models. The suit was in the prototype stages, being given to an elite special operations force known as the "Devil's Hand", sometime before the Brotherhood-Enclave War for use in cleansing operations and to maximize Enclave resources and strategic positions in the Capital Wasteland. Sometime after the death of John Henry Eden, a member of the Devil's Hand, disillusioned by the practices of the Enclave, stole one of the modern X-02 prototypes, retreating to The Commonwealth.

Location
The power armor is obtained in the Mass Pike Tunnel near the Boston Police rationing site, during the quest Speak of the Devil. The "Devil's Inferno" mod can be found in an unlocked safe in the rationing site.

Bugs
When starting a new game, the "X-02 Power Armor" add-on can cause a bug where the Sole Survivor won't be able to exit Vault 111. The opening animation does not start when pressing the button and they will be stuck in the vault. Clipping through the vault door causes other bugs, like V.A.T.S. not working. Remove the X-02 add-on, start a new game, exit the vault, then add the X-02 back.
