This game is pretty sweet however I keep coming across this major bug, it seems if the game wants to lag or anything instead I just loose control of my character and he starts running round unloading clips into the sky and walking into danger. As you can guess quite a problem especially when the arena mode is quite unforgiving (oh you died? go from wave 18 to wave 1 thankyou!) it would all be fine if I didnt keep not being allowed to play the game and just auto lose.
I tried pressing the menu button but the game wouldn't accept it. Could it be possible to have the esc key pause the game? Seems like it would be not to hard to include and only offer benifit to the game without penalty
