Final Fantasy XV: Pocket Edition is now available to download from the Google Play Store after being announced last August. The first chapter is free to play, but then you'll need to pay $20 for the full experience.
It looks like Final Fantasy XV Pocket Edition, the mobile version of the console and PC game, is just around the corner. According to an App Store listing, it will hit iOS on February 9th. The Android version may launch that same day.
Square Enix just announced a new mobile game that might actually be worth your time. Final Fantasy XV Pocket Edition will bring content from the full FFXV to mobile devices, and you'll be able to try it for free.
