Energy shields are personal protection devices that were to appear in Fallout: Brotherhood of Steel 2.
This device is issued to Lilith, Maxus and Jaffe to counterbalance Scarlet's Stealth Girl. It is not known if it has a recharge rate or instead a limited amount of uses. Its purpose however is to take the brunt of attacks that would otherwise inflict severe damage.
