And so we get touchscreen inventories (there's a Resi-like limit on space, so choose wisely between crossbows and cricket bats), touchscreen lock picking, touchscreen sniping and touchscreen location scanning. In short: touchscreen and lots of it.
Interestingly, the action on the top screen never pauses, instead switching to third person during your GamePad fumblings to reveal how close the undead horde is shuffling.
Asking eyes to be in two places at once is a cool technique, casting the GamePad as a cruel distraction where so many Wii U games see it as a cooperative buddy. I also like how death sees you respawn as a different survivor, letting you hunt down your now zombiefied old body in order to get your loot back. Smart.
