Question about the game FEAR..... help please

Hi,

I bought FEAR for my 360 a while ago and when I played it i found something to not work right. I popped it in again and realized what it was. It just seems that the games runs very oddly for instance when i press the RT button to shoot nothing will happen and then a few seconds later a shot goes off way after i pressed the button. The game feels awkward. When I fire a machine gun it keeps going even after i take my hand off the trigger. I was wondering does the game actually run like this or did I get a defective copy? Thanks in advance.

your copy must be defective because i have a copy and it works just fine. but have you looked for any scartches?

Thanks so much for the responses.
