Check out the latest Call of Duty: Black Ops sneak peak video, this time taking you into a lot of the different customizations that you can do in the game. This includes all the possible customizations you can do to your character and not only just your weapon.
This is awesome to finally be able to do this in a Call of Duty game. Now while you have slightly been able to customize your weapon in the past Call of Duty games, it has never been to this extent nor was it in Modern Warfare 2 either. So to be able to do this much more, especially finally with your character as well, is really awesome.
