Although it is essentially a remake of the original PlayStation version of Wild Arms, Alter Code F brings enhanced gameplay, improved graphics, and an expanded storyline to the PS2. Players take command of three unlikely companions in a surreal and desolate world called Filgaia. The young orphan Rudy has a unique ability to physically bond with "ARMs," or "Ancient Relic Machines," which seem to have been left behind by a forgotten civilization. The runaway princess Cecelia can command forces of magic, and the swordsman Jack is adept at a number of trades. These three "Dream Chasers" seek their fortunes in the unforgiving countryside, and might just end up saving the whole world along the way. The role-playing adventure includes overworld exploration and intense dungeon-crawling. Wild ARMs: Alter Code F is compatible with the PlayStation 2 HDD, so veteran PS2 gamers with older model consoles and the hard drive accessory can load the large, two-DVD game program to disk in order to decrease load times.
