The X-01 power armor is a set of power armor created shortly before the bombs fell.[1] It was later engineered by remnants of the U.S. military after the Great War. It improves upon older suits by offering superior protective abilities.[2]
Similar to the T-60, it appears to have a large blind spot (mainly due to the large shoulder plates) around the arms and back as they rise over the helmet. However, the oversized shoulders would provide ample spaced armor protection from various projectiles, both covering the neck joints without restricting mobility, and by adding another layer of armor to go through.
