Call of Duty Black Ops offers 50 ranks in each of the 15 prestiges. Earn XP to rank up by playing player matches. While you rank up you will unlock more items for use and more playlists. View your playercard to see how much XP you need to rank up. The following is the rank table:
Prestige Mode is a special mode in the online multiplayer for the past 4 (including this game) Call of Duty Games. Once you reach the level cap in online multiplayer, you have the option to enter prestige mode. Prestige mode gives you a special emblem next to your rank while resetting your rank. It resets everything except for clan tags (on your gun and gamertag/ID), emblems (on your gun), reticles, reticle colors, playercard, playlists, leaderboard stats, and the lifetime challenge list. A new addition to Black Ops allows you to get special playlists and leaderboard stats for prestiging atleast once. Some other special items are unlocked only through prestige. There are 15 levels of prestige in Black Ops.
Once you reach level 51 (not an actual level, but it takes a whole rank after 50), you can go to your playercard to enter prestige. Press the prestige mode button for the game to say:
“Do it all again?
Trade all of your accomplishments for a bit of prestige.
Other players will see your new Prestige rank icon in the lobby, Leaderboards, and game.”

“More Information Prestige has a price: You’ll restart at level 1 and EVERYTHING will be reset. Only your Playercard, Leaderboard rankings, Clan Tag, and playlists will be unaffected.”
