Sin Chronicle shutters it's doors on May 31

Sin Chronicle, the Japan-only non-linear RPG published by SEGA for iOS and Android in Japan last year is going offline after merely a year of active service, the company has announced. 

The game, which was marketed on the idea that players would have to make irreversible decisions that would determine whether characters would live or die, with the results being tied to a player's service account, will have been available to play for a year and 2 months when it ultimately goes offline on May 31. The game ultimately will have remained exclusive to Japanese audiences.

Per the above-linked announcement, the purchase of in-game currency has already been disabled; a number of final events will run throughout the game's last few weeks of service before the game will ultimately go offline and refunds can be requested on May 31.
