I have turtle beaches, and yes the sound is an advantage. But hitting someone with a pgp coming through a door when you couldn't see them (unless you have walls) is no excuse. And the example I just mentioned is in the duck demos. The sound in this game is buggy anyways, with the mirrored sounds its hard to get a grip of where exactly someone is, however, the sound is more important when someone is on a different surface, you know where the surface is, you know where the person is.
16:45 (of whaleys demo) he shoots me coming through front door pgp, the tries to hit rick doing the same.
also if you're going to watch that, might as well go to 15:30, where he stops and waits at the hump because he somehow knows im there waiting. Kinda like on the shaz 22 demo where he stops at the top of bridge and doesnt go forward because he knows the guy is on the ledge.
Those two points alone are obvious. If youre not going to watch all of these demos, I just employ you to watch the times given here, and the shaz demo.
