Well I looked around and decided to see if fallout 3 had any cut content, which it did from the looks of this link. http://fallout.wikia.com/wiki/Fallout_3_cut_content'

So what I am getting at is could somebody who has enough modding skills please attempt to remake some of the cut content or complete it please? Thanks...

According to that people have already added the Cryolater back into the game. As for the rest of it, that would be cool I guess, but would be hard to do well. Maybe for my first NV project, I will remake as much of the cut content as possible.

Most items that have been cut have been restored and can be found in FalloutNexus. However those cut questlines havent been restored, most likely because they could brake the game or then no one's had the patience to start restoring them.

Here's a mod for all the cut unique weapons:

Hmm... Good to know, But I guess I should have been more specific. The quests are what I was referring to though, my bad.

Yeah, the quests indeed have not been restored or atleast mods havent been released on either fallout nexus or planet fallout.

Some holotapes that were never included:

UNAR and MUAC re-adds the cut armour. My UNAR with cosmetic changes and MUAC with vanilla models (but the complete list).
