Undead knights PSP
These days, if you want to create instant fun, it seems as if the solution is to "just add zombies." Undead Knights for the PSP, from publisher Tecmo, takes this philosophy and runs with it by injecting a healthy dose of reanimated rotting corpses into mundane, screen-filling hack-and-slash action. The idea of transforming hordes of enemies into your own personal army of shambling doom is an intriguing one, but in the case of Undead Knights, the end result is little more than a Dynasty Warriors-style game sauteed in extra zombies.
You play as one of three pallid, undead warriors hell-bent on revenge. They were once loyal knights serving under King Gradis in the kingdom of Cavalier, but because the knights suspected the king's beautiful (and overly buxom) new queen of foul play and witchery, they are murdered at the behest of the king. After their deaths, a mysterious being known as "The Beast" offers to revive them as undead and grant them the power to turn their enemies into zombies under their control. Though there's a twist or two thrown in for good measure, the plot mostly serves as a straightforward excuse to make a soldier-slaying and zombie-making mess.
