On Solo, no, but on Co-Op Online/ Splitscreen, it is infinite zombie spawning until you die, you have infinite rounds in solo, but only 99 rounds on Co-Op. :) Hope this Helped
My highest round was 56
ROund 69 at Map "five". And Round 56 at map Kino
There is no highest
round 103
Zombies is endless on black ops.
Yes there is a round were zombies and zombie dogs kill
There is no end to the Zombies rounds so there can not be a highest round. The rounds or levels keep coming until you die. Zombies (also and originally known as Nazi Zombies) is a survival-type game mode. {see related link Zombies (mode)} That means you can not win and just try to see how long you can survive.
kill zombies until u get to round 100 but u need to be a pro to do it
You can't mate!!
Black Ops 2 Zombies is harder but also way funner than Black Ops Zombies.
On round 99 on Black Ops: Zombies the two player or more will stop there and there will be no more rounds just an endless amount of zombies but in single player it continues. This link is of Syndicate (#1 Zombie player in the world) getting to round 105 of Kino der Toten
Black Ops does have zombies
