Nintendo and LINE announced a Dr. Mario mobile game for iOS and Android devices a little while ago called Dr. Mario World. Dr. Mario World was supposed to release worldwide (obviously not including India because Nintendo) on July 10 but the game has gone live a day early in many regions. Dr. Mario World features real time PvP multiplayer and game progress tracking through Facebook and LINE. Watch the trailer for it below:
