Medical mystery: Mama Luigi
Nintendo has announced Dr. Mario World for release this summer on mobile devices in the US and Japan. The game is being co-developed by Nintendo, LINE Corporation and NHN Entertainment.
Dr. Mario World will be free-to-play, with optional in-game purchases. While it will initially release in Japan and the US, it’s set to release in over 60 other countries afterward.
Other than that, however, Nintendo has yet to give any other details.
