X-01 Power Armor (Fallout 4)

X-01 power armor is a set of power armor appearing in Fallout 4.

Background
The X-01 power armor is a set of power armor created shortly before the bombs fell.

A variant of the X-01 power armor was still in testing phases with the scientists at Nuka-World in 2077 as a part of a cooperative initiative between the U.S. military and Nuka-Cola Corporation when the bombs fell. This unique variant is known as the Quantum X-01 power armor, and can be found at Starport Nuka.

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.

Characteristics
X-01 power armor provides the greatest defense among all models of power armor featured in Fallout 4. The power armor bears resemblance to the advanced power armor seen in previous Fallout games.

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.

Variant

 * Quantum X-01 power armor

Level-independent

 * An X-01 helmet can be stolen from Proctor Teagan's shop on the Prydwen behind a Master-locked door, or a key may be stolen from the Brotherhood's knight-captain wandering around the power armor bays. Upon entering the Prydwen for the first time, one can spot him asking another knight about patrols or other related material.
 * Worn by Danse upon completing Blind Betrayal if one wishes to spare him. The suit is a full set of X-01 missing only the helmet, but like his T-60d, his X-01 has a locked fusion core eliminating the possibility of having Danse exit the armor.

Level-dependent

 * Two full sets found at the Nuka-World power plant: one behind a terminal-locked door in the basement, another one in the power monitoring station southeast of the plant, under an electrical tower. Assuming the player starts the Nuka-World add-on at the recommended level of 30, these armors will always be at least X-01 Mk I suits due to them beginning to spawn at level 28.
 * One full set due west of Dry Rock Gulch, on a flatbed truck just beyond the parking lot outside of the park area proper. This suit is subject to the same level considerations as the pair mentioned above.
 * A full set of armor can be found inside Fort Hagen hangar behind a locked security door. One of the resident Rust Devils may attempt an entry, resulting in a heavily armored combatant.
 * Another set can be found at the top of the 35 Court building in the Financial District. The suit must be acquired by destroying an Assaultron and a Sentry bot emerging from charge pods that have buttons which unlock the central chamber containing the armor.

Bugs

 * In an unmarked building named 35 Court, at the top after an elevator ride. After battling two robots (level dependent) one can access the center chamber containing the full suit of power armor. The armor will spawn X-01 after lvl 28 but may appear to be a lower grade armor (T-45, T-51 or T-60). However, upon suit entry it will become X-01 power armor.
 * Sometimes, when building a jet pack for the X-01 torso for the first time, it will appear a good armor's width away to the right of the rack (when facing it) and it will also be rotated 90 degrees. Once the player character enters the armor, it snaps/floats to its correct position and orientation on the back; it continues to float, not actually appearing to attach and not moving with the armor animation, though it does follow the Sole Survivor and is completely functional. Quitting and reloading the game fixes this oddity.
 * If left without power armor stand and fast traveling around, can transform into a T-45 power armor that's missing random parts. This is actually due to the "cell reset" bug, and affects power armor frames, not specifically the armor pieces themselves. This bug primarily affects modded games, and can be avoided by either using the console to spawn a generic frame and moving the armor pieces to the new frame, or by using a mod that allows the construction of bug-free frames via the workshop.
