The latest issue of Japanese gaming magazine Famitsu has revealed that a HD remaster of The Alliance Alive is in development for Nintendo Switch.
Originally released on 3DS in Japan in 2017 (and the rest of the world last year), The Alliance Alive is a traditional turn-based Japanese RPG in which you take control of a small group fighting to free the world from evil Daemons. It received fairly strong reviews on release, with Famitsu themselves awarding it 34/40.
The article only mentions that the game is being made available in Japan though and there is no word yet on whether the port will be coming to the rest of the world.
The Alliance Alive HD is expected be released in Japan this fall.
