Famitsu recently revealed that Atelier Shallie will be the latest title in the series to receive an enhanced port of the game for PlayStation Vita. Atelier Shallie Plus, like the others in the Plus rereleases, will feature DLC from the PS3 version, including swimsuit costumes, the bonus dungeon, and extra party members in Escha and Solle.
New to Atelier Shallie Plus are the inclusion of Ayesha and Logy from previous titles in the Dusk series and new event scenes featuring them. There will also be more events to further explain the overall Dusk trilogy as a whole.
