Skell Superweapons are fourteen special Skell Weapons in Xenoblade Chronicles X. They are extremely powerful weapons with high fuel costs. Each superweapon is available as level 30, 50 and 60 versions. They can be crafted at the AM Terminal after obtaining the schematics.
The level 30 FILE-USPx40xx schematics are acquired after completing the game, the level 50 FILE-USPx60xx are obtained by opening certain Treasure Boxes, and the level 60 FILE-USPx80xx schematics are obtained as rewards for completing certain affinity or normal missions. The exception are the three Hexad-Partican schematics, level 30 FILE-USP0140SA, 50 FILE-USP0160SA and 60 FILE-USP0180SA, which are all obtained by completing the affinity mission Two Peas in a Pod.
