Munchkin Zombies Question

[Johnaceinnj]

I have all the Fantasy Munchkin cards, boosters, sets, promos, etc. (at least I think I do), and I'm interested in the new Munchkin Zombies set.

Can Munchkin Zombies be combined with Fantasy Munchkin, or is it a stand alone game?

Also, is the Munchkin Official Bookmark of Braaaaaains to be associated with Munchkin Zombies, Zombie Dice, or both?

Thanks a bunch!
