Portable Nuka Jetpack
These mods grant your character access to an extremely powerful jetpack that can take you to great heights. Explore the Financial District from the air. Fly above the Brotherhood of Steel Vertibirds. Enjoy a bird's eye view of the Glowing Sea.
The best part is that you won't incur any fall damage if you plummet back down to earth. The jetpacks also come with ballistic weave.
The PS4 version requires Nuka World and it doesn't feature the jet flame that spews out from the bottom of the Xbox One version. But it works, and it's awesome, and that's what counts.
