but I have some gripes with some of the weapons being overpowered....I had a sniper and got owned by a guy with a SAW clear across the map! I hope they do some tweaking with the guns. I also hope they make some more open maps.

All in all the environments and gun detail are great. The melee knife option is awesome especially when you can sneak up on an unsuspecting sniper.
