Koei Tecmo has announced a Day One update will be required for players purchasing Attack on Titan 2: Final Battle in Japan.

Customers who purchase a physical copy of the game will not have to update their game, whereas those who pre-loaded the game or purchase it from the Nintendo eShop will need to download the Day One update, which goes live from July 4, 2019 10:00am JST.

No word on what the update does at this time, but we’ll let you know as soon as we have more information.
