i really have no idea so i just search it and hope it helps..
Rengoku: Tower of Purgatory is an action RPG, but it barely fits the genre, as the game is far more about combat and weapon management than role playing or story. Rengoku has an amazing item management system, a very hip new control scheme, and some damn sexy android designs... and that's about it. As far as gameplay goes: kill, get items, climb tower, rinse repeat. Rengoku: Tower of Purgatory is neither heaven, nor hell to play, it truly plays like purgatory, it's never ending.
