Power armor is one of the most iconic element of the Fallout series, with the helmet of the T-51b being on the box art of the first game, and associated with the franchise ever since. Every time new players jump into a Fallout game, the first thing they want is power armor - but these advanced outfits are among the most powerful in each game, and you'll need to put some legwork in if you want one.
What is the X-01 Power Armor?
The X-01 power armor is a returning design from Fallout 2, where it was known as the Advanced Power Armor and associated mostly with the Enclave, the questionably motivated remnants of the pre-war US Government. The design seen in Fallout 4 is more faithful to this original design than the variant we saw back in the Fallout 3 days, and looks like an exact and authentic recreation in much greater detail.
Power armor works very differently in Fallout 4 from a gameplay perspective than it did in previous installments, and is more akin to the lore surrounding how this technology is intended to work. Players will need a Power Armor Frame onto which individual pieces of the X-01 can be attached, as opposed to the X-01 coming as a complete set - though in rare cases you can find an entire suit in one place.
Like other power armor parts, the elements of the X-01 spawn randomly in MK. I to MK. VI variants depending on your level and what DLCs you have installed. In the base game, MK. III is the limit. The higher this number, the better the stats - that said, overall the X-01 is one of the strongest power armors in the game, so wearing it will give you a clear advantage.
