Fate/Grand Order is moving to Unity 6. FGO PROJECT announced the engine migration for mid-June 2026, and the change carries a steep storage cost. Players who already completed a bulk download before the update will need to download roughly 16GB of game data again. Those doing a bulk download for the first time will need about 30GB of free space. During peak access times, the download may take over 30 minutes, and the studio recommends using Wi-Fi due to the large data usage.
The update also sets a new supported device baseline for September 2026. On iOS, the recommended environment will be iOS 15.0 or later and iPhone 12 or later. On Android, the requirement is Android 7.0 or later with a Snapdragon 855 equivalent or higher processor. Players are advised to check their storage and device compatibility ahead of the change.
