Jetpack for power armor. (Fallout 4)

you can't find it, but collect it

PekaBoirin
4 level of science and armor is needed, if I'm not mistaken, and this is only from level 41. Placed as an upgrade on the chest piece

PekaBoirin
Can also be issued in the Brotherhood of Steel at the end of all quests.

jet pack is useless, yes beautiful, yes sometimes you can crush everyone like mario, but I think stealth fight will be more useful

As for me, it is so useful, especially in urban areas.
