yes, i have heard that it is not possible to prestige on combat training, but not sure about general offline play.
hope this helped
Get lots of kills and do challenges
You cant. You need to play online against other players and you get promoted to new levels. You can, however, play combat training against computer players and get promoted the same way as you do online, but combat training and online are separate.
Play Search and Destroy and Headquarters
Yes you can play online in black ops with psn and xbox live
Xbox isn't free online, but ps3 is. There's no exception with Call of Duty Black Ops.
Buy the Call of Duty Black Ops game, put the game in your PC or game console that has an online connection.
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.
You can play online in Call of Duty Black Ops PS3 using the online split-screen support.
black ops
You can get the Black Ops ll modeling tool online at tom-crowley.co.uk.
Black Ops is not a Lego game
The only way you can get ascenison in black ops for free is by hacking it... and if you hack you will get band from playing black ops online or from Xbox live.
