like a weapons type of bullet or deciding on which colour a shield is and the strength of that shield, but be inventive with what you do with the upgrades and spread so we have a large variety of choices. :i[color=#0000FF][color=#FF8000]
are you meaning changing lets say a fire weapon to an electric weapon?
but yeah i think like minor weapon class mods for each weapon would be nice.
Shield color is based around heat being red and electric being blue nothing fancy involved there those colors are needed to determine which route to take in a battle.
the strength of the shields are already in place. i dont understand why you would need more.
