The Halo 3 Weapons do damage in Hit points. Most appear to do the same amount of damage to one's Shield points (Sp) as they do to one's Body points (Bp), but there are exceptions. There are also a few weapons that are headshot capable, or rather have a [i]headshot bonus[/i]. These weapons are the Magnum, Carbine, Battle Rifle, Sniper Rifle, and Beam Rifle. Any damage done to a Player's head hitbox after their shields are down, or rather there Shield points are equal to zero (sp = 0), does [i]infinite[/i] (∞) damage to the rest of the player's Hp. This could also be referred to as an automatic, or instant kill. In Bungie's 2/08/08 Weekly Update, it was revealed that each Player has [b]115 [/b] Hit points- [b]70 [/b] in Shield and [b]45 [/b] in Body points. This allows one to easily conclude that the Overshield Powerup initially adds another 70 hp to a player's Shield points, with each additional [i]layering[/i] of shield also being worth another 70 shield points. All of the following was compiled based on this information.
