Pilot Damage
When a Pilot is successfully hit by an attack, reduce their Hit Points by the damage of the weapon. For example, if a Pilot on 10 HP is hit by a Pistol which deals 2 HP damage, reduce their Hit Points from 10 to 8.
If a Pilot reaches 0 HP, roll on the Critical Injury Table to determine what happens to them. They can suffer injuries, be knocked out, or even die. A Pilot's Hit Points can only be reduced to 0 HP and never go into negative values.
If a Pilot is hit by a weapon that deals SP damage, such as a Red Laser, they take 2× that damage. Weapon entries denote whether they do SP or HP damage in their profile.
