Tecmo Koei has an enhanced port of Atelier Ayesha in development for PlayStation Vita. Like the other "plus" games Atelier Ayesha Plus includes all of the downloadable content for the PlayStation 3 game onto the Vita cart. In addition, the Vita version will have a new boss and hard mode where enemies have more HP.
Another new feature called panel attack turns over panels when you clear certain tasks in the game. Gust hints that there may be some kind of bonus when you turn over all of the panels. Atelier Ayesha Plus is slated for release on March 27 in Japan. The game has not been announced for the West yet, but so far all of the other Vita versions were released as PSN titles.
