The Nanite is a secret treasure found hiding in the patch of dark blue stuff on the ground in the Armory northern. It must be given to X6 in Sleg Mine. He will upgrade Sargon to Neo-Sargon. In order to get this item, the player must activate Railjet when going to the Armory. After you obtain this item, you can use Outwarp to exit from the Armory and give the item to him.
