Last month I revealed that Mugen Souls (Aka. Infinite Souls) the next game from Japanese developer Compile Heart would allow you to not only use the games main storyline characters in your party but also custom avatars which make use of different classes and can have their appearances edited with new costumes and accessories. This trailer looks into the system a bit further, focusing on character creation, costume editing (Which is a feature afforded to I believe both custom and main character alike) and how they appear in battle.
The game is due for release in Japan on the 22nd March 2012 – expect a review of the game a week or two after launch.
