Power armor in Fallout 4 requires no training to use as it did in Fallout 3 and New Vegas, and is unique in other aspects as well.įirstly, the separate armor segments are mounted on a frame, as opposed to previous suits that existed as holistic entities that were worn whole, aside from the helmet. Once depleted, the unit will still be operable, but the movement is heavily restricted as it is dead weight. For power armor to function it requires a fusion core as a source of power, which drains over time actions that consume AP will increase the rate of depletion. Power armor is a multi-component armor unit, comprised of a base frame, with assorted armor pieces mounted on it.
