Square Enix released today in Japan the Flame x Blaze which is a new, 3 vs 3 multiplayer smartphone game. At the moment the game is available only in Japanese on iOS and Android. You can download it for free from the Google Play and the AppStore and the pre-registered users can claim their gifts already until May 11, 2017.
In this game the goal is to defeat the enemy team like in a MOBA game just with 6 players instead of 10 and players can corporate with each other in the same team. It should be noted that there will be a pre-open event which will be held in May where you can get extra in-game items as rewards.
