Zombies are everywhere at the moment. It seems wherever you look, the success of The Walking Dead has spawned zombie comics, zombie action figures and of course zombie video games. Whether it be Telltale’s episodic masterpiece or endearing smaller title’s like OMG Zombies from Laughing Jackal, the walkers are coming to feast on your gamer flesh whether you’re on board or not. Fast forward three years on from its 2009 PSP predecessor, and we have Zombie Tycoon 2: Brainhov’s Revenge. All signs point to this one offering something different; a zombie apocalypse where you have to use your brain, as opposed to playing brain dead.
