Well there's new medals such as "Kill from the grave" which is when you get a kill when your dead such as dropping a grenade before you die. A "Kill joy" which is when you end someone's killing spree. You can remove tourets from the map that and walk around with it, though you then have limited ammo. The graphics aren't anything new, but they're not supposed to be. The beta was only released to see how gameplay balanced out with some of the new weapons, and things you can pick up in the game. Overall though I really like it, and enjoy playing it.
