Several of these were produced from pre-war blueprints by the Brotherhood of Steel using newly rediscovered technology from the ruins of an industrial plant on the outskirts of D.C.
They are around two thirds of the size of the original Liberty Prime, but they are faster, lighter and more manouevrable. The head unit has been replaced with a lighter one, vocal features and the tactical lazer have been removed to save weight (and because of scarcity of parts). The right arm has been replaced with a high powered lazer unit.
