Stumbled upon copies of Munchkin Zombies Deluxe, today, at the local Barnes & Noble. Wasn't aware that it existed, let alone that it was available (apparently only from Barnes & Noble). Obviously nothing more than Munchkin Deluxe with the Munchkin Zombies theme/components.
Yeah I totally forgot about that I saw this a couple of weeks ago (long day, got home late, forgotten by the morning after), but from what I saw the only 'new' thing is the actual "level board" which is zombie inspired.
I didn't see any new cards coming with the box, which is a good thing... I'd hate to buy a second copy of the game, just so I wouldn't miss out on four 'expansion cards' so to speak..
