This is the damage system that will, with minor modifications, be used for Battleship 2. Hit up arrow to fire a shell Down arrow for a torpedo You can see some faded parts, those are damage hitboxes. If shell doesnt reach any, no critical damage is dealt, just some hitpoints are reduced from the hull bar. If it does hit modules, more damage occurs, and modules become incapitated, or destroyed. Hitting propellers halts the movement Citadel reduces engine power, deals massive damage when hit Ammo incapitates the turret and slows reload later.
