Square Enix will release PSP game Kingdom Hearts: Birth by Sleep in Europe on 10th September.
This handheld adventure turns the clock back and serves as a prequel to the series' very first game on PS2. The Disney-meets-JRPG story has "exceptional graphics" and is "one of the most beautiful titles ever" on PSP, claim the people trying to sell it.
More importantly, there's multiplayer for six people: either fighting against each other; teaming-up for a wave-based arena mode; racing on hovering Keyblades; or strategising on the Command Board.
