In Fallout 4, the jetpack is only available if you wear Power Armor. That is until you install this mod.
The latest Fallout 4 mod brings an often-requested feature to the masses; the ability to use a jetpack without the need of wearing Power Armor.
The new mod, created by user SomberX, takes the Power Armor jetpack and straps it to the back of regular armour. It can also be crafted under ‘armor’ tab at the chemistry station. “The fire comes out of the correct holes,” attests the creator.
