This is the Cyber Arm Vault Suit mod by tumbajamba, but in the box, along with the armor includes a right-arm equipped cyber arm so you can equip other armor.

I edited this for my own purpose, and thus the stats granted by this arm may or may not be to your tastes. A lot of people were asking for just an arm equipped accessory than something that was stuck onto armor, and I was also one of those. I made one for myself and decided to just upload it in case anyone wanted.

Like tumbajamba's mod, the box will be found outside Megaton's gate.

Also to note though; I likely won't update this in the near future as I've got limited time.

====Installation====
First get the meshes from the original mod by tumbajamba:
http://www.fallout3nexus.com/downloads/file.php?id=14676

Then use the ESP in the zip file here, use FOMM to tick it.

====Bugs & Issues====
The cyber arm will clip if worn with other armor depending on what you wear. Just be aware of this; I wish I had the skills to script something but...


=====Compatibility=====
It should work with any mod, I'd imagine.

===Special Thanks===
Tumbajamba, the original creator of this mod. All I did was edit it.
