The latest in Square Enix's increasingly long line of Final Fantasy XV spinoffs is now available worldwide. Players can download the mobile action-RPG King's Knight: Wrath of the Dark Dragon from the iTunes and Android app stores.

Wrath of the Dark Dragon is a sequel to the NES game King's Knight, which was notable for being the first title Squaresoft released as an independent company. Like the original, Wrath of the Dark Dragon is a scrolling shooter/RPG hybrid; players choose a character class and must use its unique abilities to shoot their way through vertically scrolling levels. The game also includes a multiplayer mode that allows up to four players to team up and battle through stages.
