A new trailer for Persona Q: Shadow of the Labyrinth has been released on the official Atlus YouTube page. Curiously, it's marked as "unlisted". Is it some sort of leak or just an uploading slip-up? Regardless, it looks great!
This adorable trailer shows off the Persona 3 and 4 heroes battling Shadows through a labyrinth of some kind. Unusually, all of the P3 characters still seem to be in their school uniforms, which may imply that this is going to be a fun little non-canon title rather than a sort of canonical side-story.
Persona staples like summoning demonic alter-egos, All-Out-Attacks, and over-the-top enemy designs feature prominently. A release date for Japan - 5th June 2014 - is revealed at the very end.
