During the recent NicoNico Live broadcast, Atlus revealed a new Persona 5 feature called the “Mementos,” a free-roam quest that is said to equal the scale of the entire Persona 4 game’s areas. Here’s a trailer for it.

This new dungeon is different from the regular dungeons for the story, and everything is auto-generated. While inside the Mementos, you’ll get to roam around using Morgana who transforms into a bus. You’ll get to pretty much check out the entire place and its areas to take on various requests.

Persona 5 is releasing in Japan on September 15, 2016 for PlayStation 4 and PlayStation 3. The game will release on February 14 in North and South America for PlayStation 4.
