Joystiq- There are hiccups, sure. Inventory management can be annoying. Some of the touch screen minigames are unnecessary. Physics can be floaty and strange, notably when fighting zombies on stairs. These minor problems, however, rarely interfere with the pulse-quickening thrill of diving into a mass of infected and coming out alive on the other side.
ZombiU isn't for everyone, but those who stick with it, through its unforgiving and occasionally frustrating difficulty, there's a an exhilarating experience to be had.
