Disgaea 4 Return is an enhanced version of Disgaea 4: A Promise Unforgotten with all of the downloadable content included with the game. What else is new for Vita?
The game will have new skills and spell. Screenshots show Peta Star, a tier above Tera Star, is one of the new elements. That probably means Disgaea 4 Return will have sixth tier magic for all of the usual spells. Disgaea 4 Return will also have additional storylines that focus on individual characters and Dengeki Online teases "that scene" pictured above is a must see for Disgaea fans.
