weird glitch yesterday - I started a game and every time I shot someone, bullets went right threw them. I had M16 with stopping power, so normally one burst will kill them. At first I thought I was just aiming off, but then I found this guy with his back to me, walked up behind him, put the gun to the back of his head, fired. Nothing, still standing. So I shot again, nothing, fired again at his back, nothing. He turned around an knifed me. lol. I exited the game and the problem was gone.
First time I ever seen anything like that. cod4 is pretty glitch free, rarely any problems but that was bizarre.
