The railgun features 3 railgun shots that can be fired in quick succession; each deals explosive splash damage. The main highlight of the railgun is that it increases troops/soldiers' damage during boss fights when equipped in your hand. It sets all troop damage to 450 to 550 damage, depending on the boss stage. The Railgun can be best combined with toxic troops, grenadiers, or any other projectile or high fire rate troop to deal the most damage to bosses.
