Also forgot to say but since Nem never made it official I will say we will have the bullets to kill be video game style, head and heart shots will gurantee a kill, headshot will kill from any distance heartshots will require that you be close enough to penetrate their armor depending on your bullet caliber. This one should be obvious a 50 anti material sniper round will kill in one hit to the body, but won't kill if you are shot on any of the limbs rather you will be dismembered. and yes that means there is dismemberment.

Lastly Nem and I discussed this but your guns will have durability, not like hardcore math calculations, but like if your gun gets hit multiple times you will need to get it repaired xD and obviously if you take a anti material round to the gun it is unusable until repaired. xD
