How to Upgrade Weapons for Earth Defense Force 5

How to Upgrade Weapons

A weapon in Defense Force 5 that can be upgraded will be identified by a number and the outline of a five-pointed star next to a stat that can be upgraded on it's item card. As the weapon increases in quality the number will increase in value and once it becomes maxed out the star will turn white. Once all stats for a weapon are maxed a star will then appear next to it's name in the 'Weapon Select' menu.

If no star appears next to the stat on the item card it indicates that the stat is fixed and the weapon can not be upgraded.
