I tried a few unranked matches as I couldnt get into any other type and had some fun... but, I seriously dont understand the characteristics of the game.
I aim for and usually think I am hitting the enemies head, however the kill cam when they spin around and kill me shows them shooting my ass or crotch.
Crytek failed biology ?

I am not joking, I fought a guy with MAXIMIN ARMOR on and shooting at his head, I drop in 2 or 3 shots and the cam showed him shooting my crotch, nowhere near my head... well the usual head anyways.
I am assuming he wasnt cheating, in fact I expected to svck as it was my first few matches in the full game, and I got a stealth kill on a dude as well

Question : Headshots count ? Aiming count ? Is there perks or weaps that bypass Armor ? Do you need to drop your foes Armor before HP ? ( Died while having 74 power in Armor mode, no headshot cam )

I am just trying to understand the mechanics here, not biching because I lost... mastery is about learning, but I didnt learn much from my defeats. I couldnt understand them...especially the cam showing the enemy shooting my crotch or ass most the time...its like headshots are not worth going for?

I′m not sure about this, but there has been some complaints that the hit-detection svcks. I haven′t noticed this but it might be what′s causing your problems
