In this week's new issue, Japanese magazine Famitsu revealed that Persona Q: Shadow Of The Labyrinth will have a map-making feature; similar to that of the Etrian Odyssey franchise.
In Etrian Odyssey, one of the big gameplay components is using the screen to create maps of the dangerous areas players explore.
Also like ET, there are certain tougher foes you may encounter, where you can choose to run or to fight them. Famitsu also mentioned that defeating these enemies will yield special rewards.
Persona Q: Shadow Of The Labyrinth comes out this fall in North America, exclusively on the Nintendo 3DS. It will also release in Japan on June 5th. Be sure to come back to CGM as more details arise.
