Gamespot has recently released a hour long video about Black Ops. It includes a lot of information, including the level requirement for a variety of things related to weapons (Camos, clan tag, ect.). You can find the video here: Be sure to watch the full video as it also previews a new map, Nuke Town which has many special features including: A sign that changes its occupation number depending on the amount of people playing at that time, a Double-Rainbow and a special surprise when you shoot all of the dummies heads off in a certain ammount of time.
