Gameplay is simple and straighforward -- you run, turn-by-turn in eight directions, from zombies, who pursue you at the same speed, and though the game runs at any pace you want (perfect for gameplay on the iPhone, in my opinion, since most of the time I'm just looking for a few seconds to a couple minutes of easy-to-pick-up action), the dread is real. Just like actual zombies, these guys shamble their way toward you with a hunger that only brains can satisfy.
The game is on the App Store now [iTunes link]. I will say that it is a touch pricey at $2.99 (a simple arcade game like this seems made for the 99-cent price point, and it will probably end up there eventually), but who am I to begrudge the developers a couple of bucks? I don't need to drink that cup of Starbucks anyway. If you're in the mood for a simple, zombified twist on an old classic, this is it.
While you're at it, check out the Zombies preview video we shot at WWDC last July.
