The X-01 Power Armor can be found in several locations in Fallout 4. Most of the X-01 suits found throughout the wasteland only contain a few X-01 parts, not the full suit, and this largely depends on what level the player is at the time of discovering the armor. However, there is one location that houses a full X-01 Power Armor suit, for players who make the effort to acquire it.
Players should be at least around level 28 or higher before searching for the X-01 Power Armor, as this will increase their chances of actually finding a suit with X-01 parts. Perhaps wait until level 30, just to be on the safe side.
To track down the full X-01 suit, begin by locating the Custom House Tower on the east side of the wasteland, near Faneuil Hall. However, don’t actually go inside the Tower. Instead, head southwest down the road until you reach the building with a sign that says “35 Court”. This is the tall green building to the left of the Tower entrance.
Enter the building, and take out the robot in the lobby. Press the elevator button to call the elevator. Ride the elevator to the rooftop, where the X-01 Power Armor is located. Prepare to fight off an Assaultron and a Sentry Bot, who emerge from a pair of side chambers.
There is a red button found inside each of the chambers the robots came out from. After taking down the defensive bots, proceed to press the red buttons inside both chambers. This will cause the door on the center chamber to open, revealing the full suit of X-01 Power Armor housed inside.
As previously mentioned, there are also several other locations where a partial suit of X-01 Power Armor can be found. One such suit is located in the Abandoned Shack northwest of the Glowing Sea, on the western side of the map.
Another is found at the National Guard Training Yard inside the armory. Look for a red metal door to the armory, and prepare to fight off some Ghouls. The armory contains a security door that requires Master level hacking skills to unlock. Bring along Nick Valentine to hack the terminal for you if your Hacker perk isn’t a high enough rank. The X-01 suit is found just behind the security door.
Remember, the chances of finding X-01 parts on suits in these locations will vary depending on player level, and the number of parts is random. Aim to be at least level 30 or higher, and create a save file before tracking down these suits. The higher the player’s level, the better the chances of discovering a suit with X-01 modules.
