X-01 Power Armor (Fallout 4)

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

Characteristics
The X-01 power armor is a set of power armor created shortly before the bombs fell. It was later improved upon by remnants of the U.S. military (the Enclave) after the Great War. It improves upon older suits by offering superior protective abilities. 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.

Variants/Paint jobs

 * Hot Rod Shark paint
 * Hot Rod Flames paint
 * Hot Rod Hot Pink paint
 * Institute paint
 * Military paint
 * Vault-Tec paint
 * With the Nuka-World add-on, it is possible to acquire a suit of X-01 power armor with a unique Nuka-Cola Quantum paint job.

Level-independent

 * A helmet can be found at Proctor Teagan's shop on the Prydwen behind a door locked with a Master level lock, 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.
 * 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 DLC 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.

Level-dependent

 * For a generalized list of locations where power armor can be found see the page power armor frame; depending on the player character's level there may be X-01 power armor.
 * Full set found in building labeled 35 Court, located just west of Custom House Tower (if the player character is level 28 or above.) Inside 35 Court go up the elevator where one will go against a sentry bot and an assaultron. Press each button inside their cages, and the door will open to the new X-01 suit.
 * Northwest of Fort Strong, follow the road, to the toll gate building. Incomplete set.
 * Murkwater construction site, head due west and look for a crashed Vertibird. To the west of the crash, is an incomplete set standing in the middle of the swamp.
 * At high levels Rowdy will sell X-01 parts, however this is fairly rare.
 * Incomplete set found in the Federal surveillance center K-21B northwest edge of the Glowing Sea and map.
 * Depending on player level, full set in a cage locked with an advanced terminal in South Boston Military Checkpoint
 * Depending on player character level, full set of X-01 armor can be found in the Fort Hagen satellite array (Fort Hagen hangar), just west of Fort Hagen. If the player character is not level 28, lower versions of power armor will be spawned instead, such as T-51 power armor or T-60 power armor
 * It is possible for X-01 parts to spawn on the power armor frame found at Bradberton overpass.

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.
