ysy started the official open beta test of the upcoming smartphone card battle game the Revolve. The OBT version of the game available for the iOS and Android users but only in Japanese and only from Japan.
The ending date of the Open Beta Test is not announced but DO NOT delete the game after the OBT ends, because when the official game release you only need to upgrade and you can move the data file to the final version (if you delete the OBT client you can’t move the data and you will lose everything).
If you enter into the OBT you will get extra items and card to your first deck so it’s worth to try it. You can still pre-registered for the game which is by the way reached the 100 000 pre-registered users until now.
