Okay since we know that Navyfield Mobile has simplifies the game mechanism in ship customisation as well as damage calculation. There is no any AP (armour piecing) shells nor HE (high explosive) shells to choose, but the game seems remain deck impact and belt impact, and allows ship to upgrade armour for protection. What is the effects of armour in reducing shell damage? Is it a straightforward reduction in damage, or in percentage? What if a vetted repair crew affect the calculation, with and without armour? Would different guns have different hidden stats (like armour piecing and explosive, as well as their shooting angle)? I will be thankful if devs and mods can uncover more details about it. Or any players can share?
