Multiplayer leveling in Call of Duty: Black Ops for the PS3, Xbox 360, and PC is basically the same as you’ll remember from Call of Duty: Modern Warfare 2, in that you gain ranks up to 50, and then you gain an prestige and start all over again. Call of Duty: Black Ops goes up to prestige 15 though instead of 10, in case 10 wasn’t hard enough for some of you freaks out there. The whole thing reminds me of WoW grinding, but longer.. ugh!!
Here is a list of the what you unlock on your way to the god like rank of prestige 15.
Rank Level 4 – Create a Class
Rank Level 5 – Contracts
