Square Enix continues its campaign to put Chrono Trigger on every single device you own, with the announcement of a version for Leapster iPhone.

The Square Enix Members blog reveals that an iOS release of the classic RPG will be available "before the end of December." No price was announced, but Square Enix tends to be bold with iPhone RPG pricing: Final Fantasy Tactics: The War of the Lions debuted at $16, and even the port of Final Fantasy is $9.

The iOS game uses a virtual joystick for locomotion, and a touchscreen menu for battle, neither of which should cause trouble in an RPG. You can see the new battle interface above; check out our gallery for more.
