Today several news outlets reported that Square Enix has announced the development of Final Fantasy XV Mobile. The project will be a collaboration with Korean developer JSC (Joyful Space Creator) and Chinese developer GAEA. Chinese publisher Shanghai Oriental Pearl Group will bring the game first to the Chinese market.
The game will use the Unreal Engine 4, feature multiplayer gameplay options, and have a story that parallels that of Final Fantasy XV. Not much is known about the game otherwise. More information and a trailer are scheduled to be released in the first half of 2020.
