Being the Wii version...
... No wonder this could actually happen. Waggling the wiimote against the hundreds of enemies that appear onscreen endlessly causes you a major cramp that forces you to drop the device, making Aya helpless. WHY THEY DIDN'T PUT A CLASSIC CONTROLLER OPTION BEATS ME.
You fucker... I was suspecting you'll grab this chance to make some ero-gro mischief! You're being a bit misogynist nowadays... Girl you take, girl you break.
But I'm happy to see so many zombies! I secretly wished you draw lotsa zombies everywhere... And you did it!
Anyway... 70 hours and more than 10.000 zombies killed... And I haven't unlocked this wallpaper yet...
Oh, yes it's from the Wii version, Haha...!
(It's the Wii version... It's the Wii version... Keep repeating that to yourself and your world won't crumble to pieces... It's the Wii version... *sniff*...)
