The original Zombie Tycoon is one of the rare Minis that offered full 3D graphics. Canadian developer Frima Studio crafted a cute RTS that had you controlling a variety of zombie types in a night of rampage.
The sequel, Zombie Tycoon 2: Brainhov's Revenge, is a bit more ambitious than its predecessor. Unlike the Mini that inspired it, the sequel is a full PlayStation Network title, with cross-play support across both PS3 and PS Vita.
Zombie Tycoon 2 is powered by the Unreal Engine 3, promising a much more graphically intense game than the original. In addition to a single player campaign with "console-oriented RTS action," there will also be a new multiplayer mode as well.
