Fate/Grand Order: Waltz in the Moonlight/Lostroom will end service on July 26, 2021. However, there will be an offline mode. This mode will allow players to access some features within the app, such as the ability to replay songs in the app. With that said, there are some stipulations to the offline mode. [Thanks, Famitsu!]
Players will need to download all music data before end of service in order to access music. If you have deleted your app and reinstall it before the end of service in order to access music, you will need to re-download the songs before the app goes offline. Songs will no longer be available to download after this period.
Additionally, AR mode will no longer be available once the game goes offline. When the end of service date arrives for Fate/Grand Order: Waltz in the Moonlight/Lostroom, the app will also be removed from both the Google Play Store and Apple App Store. The app will no longer be available to download, or re-download, after this period.
Fate/Grand Order: Waltz in the Moonlight/Lostroom was initially made available to download on August 25, 2020 for a limited 24 hour window. Later downloads would be exclusive to Japanese users. The app features Fate/Grand Order character Mash. Players can dance with her in this simulator to various music tracks.
Fate/Grand Order: Waltz in the Moonlight/Lostroom is available on iOS and Android devices to Japanese audiences. End of service will occur on July 26, 2021.
