Search and destroy
Fastest way to get cod points:headquarters or wager match Level up:search and destroy(I like hardcore best) Sabotage or headquarters
Go on recruit, put the score limit to the highest and make the time limit to unlimited. That is the fastest way.
you get up levels by killing people then prestiging at lv 50 i found that the fastest way is to use the asp pistol and nothing else u can get up levels faster that way
hardcore capture the flag
play halo
get headshots and play domination and try to get more flags than killing bacause you get more XP
Black ops is way way way way way way better ci crap
To get promoted in Black Ops you have to kill people, completing challenges and you go up a level all the way to 51 ( Only Shows level 50 but you need more XP after level 50 ) and then you can prestige and start again.
The only way to do that is to finish the campaign and play the last level. In that level you will be let out of the room.
Do quests.
