I can see it now. Woo SHOOT MY ZOMBIE FRIENDS MODE!! I'd love that. ALL MY FAMILY IS DEAD Multiball, hell yes... Smell the Rotting Flesh bonus multiplier... My Kid Is Missing In The Forest Full Of Zombies Hurry-up. Wait, no, all that sounds like it would suck.
Zombieland, Shaun of the Dead, Rob Zombie, Resident Evil, all those make a little more sense thematically.
