"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."
"For the most part though, the GamePad only enhances what is already a wonderfully frightening experience. Granted, none of these features really need a second screen to work, but they do add an extra layer of perceived reality, and the radar in particular feels completely natural. In another clever turn, the GamePad speakers also serve as the speakers for radio transmissions, again adding to the illusion.
In the end, it's the atmosphere of ZombiU that sticks with you. With your life hanging by a thread at any given moment, it demands keen, breath-held focus. You can feel it when your survivors' voices shake as they split the skull of an undead, in their panicked panting as they sprint from danger. There's no one to help you, no respawns. It's just you, a pack full of supplies (if you're lucky) and the horde. You develop your own rules, a code that will ensure your survival. Don't shoot first. Assess the situation. Know your exit. Live."
