COD Zombies is always fun. Left 4 Dead was always great. At the moment though it's one of those two. I never really had a favorite.
in order of awesomeness;Borderlands DLC (Zombie Island of Dr Ned)L4DL4D2Survival Crisis Zalso can't wait for Dead Island. Supposed to be great! hope it delivers :P
l4d is classic but you can try nation red also
I can't wait for Dead Island. XDAnd would it be incredibly lame if I said Dead Rising 2 was my favourite zombie game? =P
Honestly,Left 4 Dead and Zombies Ate My Neighbors are some of my favorites.
I like to play the Sims, but I just pretend everyone is a zombie..
hmm.. Left 4 Dead is probably my favorite, but also the Dr. Zed DLC for Borderlands and Prototype (which is...sorta Zombie)
Resident Evil 4 was brilliant. Looking forward to Dead Island also - the trailer was amazing.
