The ranking up system consists of kills, revives, perks drank, headshots, etc. The levels are : 1 Bone, Crossbones, Skull, Skull & blue eyes, Skull & 2 Shotguns, & Skull 2 Shotguns, & blue eyes. In that order. There is also tally marks. That shows how close you are to ranking up. Lastly, it also is the rounds you make it up to. I'm max rank. Hope this helps!
Yes, you can level up online for competitive online only. You do not get experience from Zombies.
No, there is no way to actually "win" at zombies. It will keep continuing to go up in level until you and your friends die from the endless waves of zombies.
go to you tube and look up gliching in black ops
Call of the dead is really hard I only got up to round 15.
