Weapons

Most creatures are immune to certain weapon types and the types before them. So it's recommended to craft a new weapon type as early as you can after getting finding a broken weapon.

List of types
(with all types of weapons if you HAVE to use the one you pick up from missions go ahead. I would save my antibiotics and other usefule upgrade parts for the upgraded version of the weapon (which has one for every weapn) that you can get from trading in silver.) The stats are by far better. Don't make the mistake of upgrading a weapon to level 15+ and getting a custom weapon which you are bound to come across either through 5-star mission completion or trading in silver)
