Square Enix's MMORPG also launches today on the Xbox 360.

Key Features:

• More than 10 exclusive areas: Explore new places such as Mamook, Arrapago Reef, Al Zahbi, Aydeewa Subterrane, Nashmau, Wajaom Woodlands and others.

• 3 brand new jobs: Become a Blue Mage, wield elegantly curved blades for close combat while decimating enemies from afar with fell magic mastered from your opponents. Experience the power of being a Corsair and rely on the "Hexagun," a multi-barrelled revolver, and elaborate luck-based abilities to alter the stakes of battles. Control enemies' minds when becoming a Puppetmaster.

• A horde of adversaries: Treasures of Aht Urhgan will unleash numerous monsters on Vana'diel such as the artificially created Lamia beastmen, amphibious Merrow chimeras or the Mamool Ja, a powerful tribe that holds dominion over the new Mamook Ja Savagelands.

• Two fresh game modes: "Besieged" game mode will allow players to defend their towns from monster-invasion while "Assault" mode will let players over level 50 jump in and play straight away without having to assemble a giant party and undertake a huge quest.

• Chocobo breeding: Raise and care for your very own Chocobo, a feature for which fans have been asking for the past years. Mate your Chocobo and some little baby Chocobos might be running around the fields of Vana'diel soon!

• System enhancements: Keeping with the FF XI principles, system enhancements in addition to those listed have been implemented to enrich gameplay in a variety of ways.
