alterOps zombies?

Is there a way to play zombie mode with alterOps?
If not, is there a way to play the dlc zombie maps at all? (other than owning them on steam)?

They dont support zombies as of now, and have no real intention of doing it until MP is done. That is if they plan on doing it at all.

is there any way (not alterOps) to play the zombie maps from the dlcs?

Unfortunately not from what I've seen. I've also been waiting for some time for someone to get around to doing it, but nobody has.
