Until House of the Dead over to the iPhone, you can indulge your zombie-killing tendencies with Zombie Crisis 3D. It plays out like an arcade light gun game; you have zero control over the movement of your hero. All you do is point and shoot. This lack of "control" doesn't upset me too much, as I have a real fondness for light gun games and Zombie Crisis 3D does a good job replicating that arcade experience. ---IGN

Zombie Crisis is an intense, finger-friendly 3D rail shooting game for the iPhone/iPod Touch.

Abandoning the 'traditional' joystick-based FPS, Zombie Crisis releases your fingers from the difficult movement & weapon control and delivers a new, innovative style that lets you focus on the action.

In Zombie Crisis, a bio-accident has taken place at the Argo Company, turning its infected staff into bloodthirsty zombies. When the disaster is about to sweep through the States, a female mercenary soldier, Dana, receives an order to investigate the situation at Argo's lab. Will her investigation lead to a one-way street into those dangerous zombies? Or will she find something even more dangerous than the Zombie Virus?
