Thresholds

The table below shows for each level of the railgun damage research how much (normal quality) railgun ammo is required in order to kill a big (B) or huge (H) promethium asteroid or other huge asteroids. This takes into account, that the railgun turrets automatically overkill asteroids by 1%.
