Fallout 3 Power Armor

Power armor are types of armor in Fallout 3.

Gameplay
Power armor can only be worn if the player character has gained the Power Armor Training perk, either by talking to Paladin Gunny in the Citadel, by starting the Take it Back! quest, or by completing the Anchorage Reclamation simulation.

T-45d power armor can be repaired using components from the T-51b power armor, but the reverse is not possible. All non-unique variants of T-45d power armor have identical properties and effects, and only differ in their appearance and use in certain quests.

Variants
 

Descriptions

 * Brotherhood power armor and Brotherhood power helmet - It has the same appearance and attributes as regular power armor. There are no differences other than the name, the insignia on the shoulder pauldrons, that it will not appear in a merchant's stock, and Protector Casdin will not accept it as part of The Outcast Collection Agent unmarked quest.
 * Outcast power armor and Outcast power helmet - A variant worn by Brotherhood Outcasts. Visually it is a standard suit of Brotherhood of Steel power armor but haphazardly repainted black and red. Having Outcast variants in the inventory (equipped or not) when speaking to Protector Casdin will cause him to confiscate the armor unless the player character has gained the Outcasts' trust. Wearing a full suit of Outcast power armor will cause the Outcasts stationed at their outpost to treat the player character as though they were a member as opposed to a "local."
 * Lyons' Pride power armor - It is the same as regular power armor, except that the Lyons' Pride insignia is on the shoulder instead of the standard Brotherhood of Steel insignia. There is no specific Lyon's Pride power helmet. Pride members wear either standard power helmets or the Brotherhood variants.
 * Linden's Outcast power armor - A unique Outcast power armor obtained as a quest reward for completing the quest Oasis in Leaf Mother Laurel's favor.
 * Prototype medic power armor - This is a variation of the Army power armor equipped with a Mister Gutsy-like onboard artificial intelligence. The armor's primary function is to administer Med-X when the wearer receives significant damage. Because artificial intelligence is capable of speech it will also alert the wearer to the presence of nearby enemies and vice versa.
 * Ashur's power armor - A unique version of the standard power armor which has been painted and adorned with various tribal emblems.
 * Tribal power armor - A damaged suit of Brotherhood power armor, patched and altered by unnamed inhabitants of the Pitt to resemble Ashur's power armor.
