Fallout 4 Best Power Armor Locations Guide: Where to find the X-01 Mk. III GameGuides  Fallout Guide Fallout 4 Fallout

Fallout 4 made major changes to one of the most iconic elements in the entire series. The Power Armor, formerly just the best armor you could find in the game, has now become an entirely new gameplay element. First you have to find a Power Armor suit, then you have to trick it out with the best pieces of armor that you have. Finding good ones can be tough, but there’s one surefire way to nab the biggest and best set of Power Armor in Fallout 4. Here’s our Power Armor locations guide on where to find a full suit of X-01 Mk. III Power Armor in Fallout 4.

One important thing to note here is that this set spawns based on your level. There’s a few pieces to the equation, but the general consensus is that if you’re above level 26, you should be in the clear. The higher you are above that the more sure you can be that the suit you find will be the X-01. Just try to wait as long as you can before heading here to be sure you get what you really want.

So, down to business. The X-01 is hidden away on a roof in downtown Boston, in an unmarked building that is guarded by some fierce robots. Being unmarked, it can be pretty tough to spot, but if you know where to look it isn’t a real problem. Your starting location should be Goodneighbor, so head there and then leave the town. You’ll want to head east, toward the coast, though it’s only part of the way there.

The location you are looking for is Custom House Tower, an inauspicious building amid the rubble. This isn’t where the X-01 Power Armor is though, but it’ll get you close. Once you find Custom House Tower face toward the entrance and look to the left. There will be two teal buildings, you are looking for the taller and further away one. Head toward it and on the left side should be an entrance that is marked 35 Court.

Enter the building and go up the elevator. This will stop halfway up the building, so look around for the other elevator on this level and take it to the roof. This is where the X-01 is, but you need to do a bit of combat first. And by a bit of combat, I mean you have to fight off an Assaultron and a Sentry Bot. By utilizing the outer scaffolding you might be able to kill these guys with minimal fight, but it’s going to be tough no matter what you do.

One strategy that I enjoyed was tossing a few mines down as soon as I got to the roof, then throwing an Artillery Smoke Grenade, and hiding down below. The Assaultron will still come down, but you can take him out while the artillery takes care of the Sentry Bot. However you do it though, just kill these two robots and hit the buttons in their containment chambers to unlock the Power Armor. If you did it all right there should be a full suit of X-01 Mk. III Power Armor, the best and rarest set in Fallout 4.

    Only problem is when I get up there it doesn’t open and no robots come out but I can see the armor

    • Kyle Hanson

      Are the robot chambers open to the left and right of the power armor? If so hit the buttons inside. If not….you may have a glitch on your hands. Got an old save you can go to?

      • eastnystunna

        Nope the robots are still inside and don’t come out to fight or the orange lights don’t even blink. Old game save is not a option for me.

        • Kyle Hanson

          Hmmm, they were triggered automatically for me. What level are you? Only other idea is that you’re not high enough level to trigger it…though that’s a longshot.

          • eastnystunna

            Lvl 34

          • eastnystunna

            Now I’m at 36 and tried again

  • Paladin Knight

    There is another easier location to find the armor.
    – Go to the National Guard Training Yard (I hope I spelled correctly)

    – Still in exterior, there are several “container” dumped outside in one of it’s corner with color (green or blue or yellow – I forgot).

    – In one of the container there is a lock door contain a full X-01 power armor.

    • Buddhaman

      There was a set of T45b there when I looked

      • Doc

        If you were under level 28 it wouldn’t be X-01

        • xAsianobey

          Idk I was level 64 and it still spawned T-45

          • Spaz

            At first it will look like it but when you enter the texture will change

    • Matt Coleman

      There was t45 for me

      • Evan

        There is a small building at the national guard training yard called the national guard armoury inside is a nearly complete set of x-01 1-2 pieces missing when you come out there can be a sentry bot sometimes it will be legendary so watch out! Hope this helps.

      • Spaz

        When you go in it changes

  • RockstarRepublic

    Found a set in the swamp…sent my companion into it… didnt realize it bugs out and the companion destroys the pieces… giving them an empty frame, nothing more.

    • Ross

      Speak to the companion that was wearing the armor, they will have the broken pieces in their inventory, you can trade with them to retrieve the pieces and then repair and re-fit the pieces to the frame

  • Sorelle

    Did you run to the door where the suit is? That’s what triggered it for me.

  • Matt Coleman

    I got t60 power armor

  • Kaitlynn Pfannschmidt

    Isn’t the BOS V t-69e better? It looks like these are a downgrade

  • Chris M

    I found a suit of X-01 power armor in the tunnels during the Big Dig quest (I think that was the name of the quest — the one where Bobbi wants you to help her dig into the Diamond City strongroom).

  • Ryan Sparreboom

    Boom sweet got it thanks a bunch for the tip also I found a mostly complete t60 at the security check point entrance to fort strong was only level 16 ish at the time
