Tribal Power Armour
As Americans it feels weird to spell armor as "armour" but we'll make an exception for this amazing Fallout 4 Power Armor mod. This one is especially awesome if you played Fallout 3 The Pitt.
Tribal Power Armour for Xbox One delivers one of the coolest looking pieces of Fallout 3 Power Armor to Fallout 4. The Tribal Armor Power Armour is based on the armor worn by one of The Pitt's (a city featured in the game's DLC) characters, Ashur.
As of right now there are three sets of Tribal T-45 Power Armour. You can add mods but you obviously can't put on a custom paint job. And why would you. One of the variants features a jetpack if you're into that sort of thing.
To obtain the armor you must defeat three groups of difficult Pitt Raiders.
