Dragon Quest II picks up after Dragon Quest where you play as a descendent of the legendary hero Loto. When a messenger brings word of an attack from Hargon the Wizard, your father, sends you on a mission. It’s lonely at first, but soon the Prince meets two allies, of course, a healer and a wizard.
Dragon Quest II for iOS and Android uses the Super Famicom remake as its base. If you want to play the game you need to download the Dragon Quest Portal app (iOS here, Android here) and purchase Dragon Quest II as an in-app purchase for 500 yen.
