Playercard

Playercards is a feature that has been confirmed to appear Call of Duty: Black Ops to act as a replacement for callsigns and titles. They will be customizable and can be colored multiple colors, the emblems will be resizable and stackable, with at least emblems and backgrounds being able to be chosen. The emblems will still have to be unlocked, however.

Trivia

 * It costs 1000 CoD points to unlock the ability to buy emblems, and 100 more points for each one.
 * There are 304 different emblems.
 * You can have and collaborate up to 11 emblem characters at once, for the ultimate "your own" design and identity. Granted you have to purchase each layer using CoD points.
