Toukiden: The Age of Demons developed by Omega Force and published by Tecmo Koei is aJapanese take on the third person action/RPG monster hunting genre made famous by the fantastic Monster Hunter series.
It places players in control of a warrior tasked with fending off waves of monsters and even big ones which Toukiden does pretty well and matched with the graphical capabilities of the PlayStation Vita, it visually impresses, in fact, Toukiden has the best looking character models available for any handheld.
The land of Nakatsu Kuni has been plagued with hordes of demons thanks to the sudden uninvited emergence of great demon 8 years ago. Utakata Village is headquarters of a band of warriors called Mononofu or Slayers, whose job it is to defend the village and rid the land of these demons. You are a newbie who has recently joined the Slayers which means it is now your job to get rid of the demon threat too.
