I highly doubt it but nobody has made it past round 150 very many times.
it never ends
The rounds are unlimited
For zombies infinite rounds does not end, even in dead ops arcade.
No
infinite
It does have a zombie mode and it is really fun.
There is no limit to levels on Zombie Mode in Black Ops. It is a survival type game mode and does not end except when you die. There could not be a number of levels because it is infinite with new levels continuing until the game ends when you die.
Get enough points and save up the points then look on infinite ammo and see if you can afford it.
There is not a highest round. The Zombie mode is a survival type format that you can not win and can only continue the new levels until you are killed.There are an infinite number of new levels for every one of the Call of Duty zombie mode series maps for All three Treyarch developed Call of Duty Games (Call of Duty Black Ops, Call of Duty Black Ops II, and Call of Duty World At War) with the Zombie Maps 5 bcause i got close to my personal best but died on dogs also add on psn - ImJustHuman
If you get call of duty black ops there is a zombie mode and you can play it online.(There are other call of duty's with zombie modes.)
in call of duty black opps
The best zombie map on black ops is the Call of the Dead but really its your personal opinion
