ZombiU actually sounds pretty neat. It's basically DayZ-lite / Infinity Blade like. You play as one survivor until you die, then you start over as another survivor. As the new survivor you can go back to where your previous survivor died, who is now a zombie, to reclaim your items. But it misses the human element that makes DayZ interesting.
Problem is it uses the Wii U screen mainly as map. Ass Creed 3 uses it as a map/inventory. Aliens uses it as motion tracker/map. Pikmin uses it as a map.
