Follow Yuri Lowell, a resident in the Lower Quarter of Zaphias and former Imperial Knight, as he accepts a mission to retrieve a stolen Blastia Core used to regulate his neighbourhood's water supply. This simple mission spins into a series of events that finds Yuri befriending a colourful cast of characters, travelling to exotic locations, and being pushed into the middle of a nefarious plot that threatens the destruction of the entire planet.

TALES OF VESPERIA Definitive Edition features two new fully playable party members for the West; Patty Fleur, a young pirate searching for her lost memories, as well as Yuri's rival and best friend, Flynn Scifo. Along with these two new playable characters, TALES OF VESPERIA: Definitive Edition will include additional scenarios and locations that will be all-new for players in the West. 

TALES OF VESPERIA Definitive Edition uses a specialised version of the TALES OF series' Linear Motion Battle System for combat. Players control a single party member in real-time combat while the other three-party members are controlled by a customised set of A.I. commands. Players can swap between the four characters at any time during battles and can perform both physical and Mystic Artes attacks.
