Kingdom Hearts 2 (PS2): Cheats and Codes

Kingdom Hearts II
Publisher: Square Enix
Developer: Square Enix
Release Date: Mar 28, 2006

Kingdom Hearts II has made many improvements with a new game play platform, good environments, and great music and acting. However it is still really easy to play and there is too much button pressing for most people. It is, however, a long awaited sequel and will really sell well from the following from the first Kingdom Hearts.
In this game, you are in the role of Sora. You really travel throughout the land with Donald Duck and Goofy to rescue friends. You will find characters from Square, Disney, and A Nightmare Before Christmas. It's a fun little game, if not widely challenging.
