Power Armor Frame

The power armor frame is a piece of armor in Fallout 4.

Characteristics
The power armor frame is the base on which all power armor parts can be added and requires a fusion core to function. The base frame provides a boost to Strength, Damage Resistance, and Energy Resistance, even without any armor added on.

Locations

 * One can be found in the abandoned shack.
 * A frame can be found on the top of the double-layered overpass highway triangulated in between College Square, Graygarden and the Corvega assembly plant. If the player character fast travels to College Square and heads west, they should see a small yellow elevator that can take the Sole Survivor to the second layer of the overpass. There's a crashed vertibird hanging over the edge with a leveled power armor standing next to it.
 * One can be found on the top of Court 35, west of Custom House tower. Guarded by a sentry bot and an assaultron. The frame is in a locked room that opens when the red buttons in the room the robots came from are pressed. Both robots will automatically self-destruct if the player character gains the Hidden status after releasing them, leaving the power armor completely unguarded.(Confirmed X-01 FULL set at level 28, MK2 at level 32, higher models may spawn at a higher level)
 * One can be found underwater next to a crashed vertibird outside Covenant (most of the vertibird is submerged underwater with only a small part of its wing visible above water to the player character).
 * One can be found to the south of Drumlin Diner nearby a destroyed train, behind a sealed security gate that can be opened via an advanced-level terminal.
 * One can be found in the green container in front of the Federal ration stockpile.(One of the raiders will get into the armor during combat.)
 * One can be found in a locked trailer at Fiddler's Green Trailer Estates east of Fort Hagen, The Trailer can be opened by key found inside a novice-locked safe within the Office Building near the pool or by picking Master difficulty door lock.
 * One can be found near the beginning of the bridge (in a small guard house) to Fort Strong when walking to it.
 * One can be found during the quest The Big Dig for Bobbi in Goodneighbor, in an optional side-passage that can be drilled by the robot. There are Mirelurks inside.
 * One can be found in a warehouse south of Greater Mass blood clinic.
 * One can be found standing at a military checkpoint under a billboard southeast of Greater Mass blood clinic and northwest of Mass Pike Interchange.(Just walk straight between the 2 locations, the check point is on the road inbetween)
 * One can be found in a small body of water southeast of Jamaica Plain and northeast of Hyde Park, in front of a partially sunken APC. *Note the suit may be sunken out of sight.
 * One can be found at a military checkpoint just south of Big John's salvage and north-west of Jamaica Plain.(Guarded by a Mister Gusty)
 * One can be found in Mass Bay medical center in the mass bay radiology room.
 * One can be found locked inside of a cage at a military checkpoint, which is located northeast of Mass Gravel & Sand (which itself can be located north-northeast of the Cambridge Police Station). The cage is locked with an Advanced difficulty terminal.
 * One can be found west of Murkwater construction site in the southernmost swamp. Beside a crashed vertibird guarded by a Mr. Gutsy.
 * One can be found north-northeast of Nahant Sherrif's Department, on a cargo floater with military vehicles on it. The frame is found inside an open blue container behind an advanced locked door.
 * One can be found in the National Guard training yard behind a master-level locked door and a terminal that must be hacked.
 * One can be found on the northwest outskirts of the National Guard training yard, a suit can be found behind a locked gate inside a shipping crate.
 * One can be found northeast of the Poseiden Energy Turbine 18-F and direct south of West Everett Estates next to a crashed plane and broken down tank and an utility protectron.
 * One can be found in one of the Revere satellite array's dishes.
 * To the northwest of Revere satellite array and northeast of the National Guard training yard and direct west of Finch farm, on the road there is a military convoy guarded by a Mr. Gutsy. A frame with a set of parts can be found inside the truck. (Level Dependent on armor)
 * Northeast of Sanctuary Hills in between USAF Satellite Station Olivia and the Robotics Disposal Ground there is a crashed vertibird with power armor
 * One can be found behind an expert-level terminal at the South Boston military checkpoint.
 * Four frames can be acquired in the mechanical bay of The Prydwen, two can be acquired without stealing. The first is acquired if the Sole Survivor has aligned with the Brotherhood of Steel and been promoted to knight. Another is given after completion of Blind Betrayal.
 * One can be found north of the Old North Church. The power armor is located on a partially sunken barge. It is easily recognizable from the Vertibird that has been tipped on its side, as well as there being several APC-like vehicles present. Hidden among the vehicles will be a cage with a Terminal on the side. Simply hack terminal in order to unlock the security gate on the cage and gain access to the armor. This suit can be found with a fusion core already inserted.
 * One can be found during When Freedom Calls or at any other time on the roof of the Museum of Freedom.
 * Just off the road at the southwest shore of Lake Cochituate, directly south of Natick Police department and Natick Banks.

 * Atom Cats garage from Rowdy. One can be stolen from this location as well.
 * Commonwealth Weaponry in Diamond City
 * KL-E-0 in Goodneighbor
 * One can be ordered from Proctor Teagan on The Prydwen.

Bugs
If one tries to modify a power armor frame that has no pieces on or in the inventory, the Sole Survivor can become stuck in an inescapable animation loop. Loop stops after about 30 minutes if you wait. One can get out of this by using the movement button rather than the back button that that would've been used to exit the modification menu, similar to getting out of chairs while sitting.
