The only thing I find I'm not enjoying is the lack of hand-to-hand combat. Maybe it's just because of the other types of games I usually play, but whenever an enemy gets close to me, I instinctually hit the Square button to punch them...only in this game, it doesn't do anything! If an enemy is that close, I feel I should at least be able to whack them with my bow or the butt of my gun. Instead, they usually end up stabbing me in the neck.
One of the upgrades you can get is to be able to whack them with your ice axe.
