The loot boxes will be available from weekly and event rewards. Players will be able to earn "1 Legendary Loot box in the Free Battle Pass, and an additional 2 Legendary Loot boxes in the Premium Battle Pass". The boxes themselves will allow players to earn various cosmetic pieces, such as skins and emotes.
Players had reported they were unable to access additional content purchased for the iOS game, which the publisher has stated was due to changes made to the in-app purchases model.
"Further investigation revealed that we are unable to completely fix the bug and implement the new changes, making it unlikely to resume service for the game," a notice from Square Enix reads. "Thus, we must regretfully announce that we will end support for the iOS version of Final Fantasy Crystal Chronicles."
Square Enix has confirmed the other versions of the game remain unaffected.
