Square Enix has announced that Final Fantasy IV is heading to iOS devices on the 20th of December. This is the 3D, enhanced version released on the Nintendo DS in 2008 though, rather than the SNES original.

The game tells the story of Cecil, a Dark Knight determined to thwart the evil schemes of a sorcerer called Golbez, who plans to destroy the world using a bunch of crystals.

It's expected the game will go on sale for somewhere around $20, which puts it in line with Square's aggressive App Store pricing scheme.

To celebrate the forthcoming release, and the fact it's Christmas soon, Square has put some of its other iOS titles on sale, with Final Fantasies I through III all getting discounts, as well as Final Fantasy Dimensions.

The sales won't last though, so if you're after some RPG in your pocket action you'd do well to get the games grabbed sharpish. Square's other big title, Lara Croft and The Guardian of Light will be on sale in a few days as well.
