played for about an hour so far. The game seems tighter and less frustrating than the first. The AI goes down without having to pump a whole clip into them. Still have yet to check out the multi.
That was fixed in Crysis by a patch. I just replayed it last month and noticed that right off.
They did up the damage for the korean assault rifle, it was way too low. Note that putting a silencer on your rifle dramatically lowers its damage output, especially at range. So if you want to take people out at range, either use an unsilenced rifle, or get in closer. The Korean AR just sucks with a silencer at range.
