I think i find somethin, that really breakes the game for me.
As it seems you can make stealthkills, whenever you get behind someone (which is nosense, cause you arent hidden, if someone saw you and he turns around, he knows that you are still there!)
So like i saw in videos from the MP, a few times someone faced a enemy in combat and then get stealth killed from another enemy, he allready saw, but then get behind him.
And cause that isnt Ninja Gaiden or some other game like it, you cant fight multiply enemys around you.
So everytime you chose to fight against someone in melee (specially if it takes a bit longer and we know how fast aliens and preds can be), you be in danger to get an instant kill from behind, EVEN you saw the one. Can be a little bit frustrating, hm?
I mean, if you got enough imigination and be able to think rational, you can see where that leads.
I mean...What the hell?!?!?!
