His armor is made out of A+ Grade titanium and composite metals, Xeno blood has melted through several feet of titanium in seconds before, the Xenomorph warriors are bullet proof and it takes several armor piercing rounds to kill just tone and you seem to forget that the Pulse Rifle has a larger magazine and faster rate of fire and more powerful bullets than the MA5C it's going to take him more ammo to kill one Xenomorph due to the quality of his weapon, Acid will affect him it will start to deplete his shields at a steady rate I mean if fire can drain his shields acid should, Also the covenant does not exist anymore >_> so much for being organized they had a civil war Xenomorphs are more organized since they have a hive mind and they've existed for eons which is plural for billions of years http://wiki.answers.com/Q/1_eon_is_how_many_years WAY WAY WAY longer than the covenant existed and there still functional unlike the covenant >_> who had spaceships and technology.
