Just watched a portion of a playthrough here: http://www.youtube.com/watch?v=flJSag3xFNQ&feature=relmfu
I totally understand the survival horror genre thing while watching this... Zombies popping out of nowhere, scrambling for ammo, feeling like your character is awkward and clumsy while switching ammo... And then at around 6:30 in the video, I got legitimately scared when a zombie dropped from above...
I need to stop reading reviews of ZombiU, the reviews are actually starting to piss me off a bit. :/
