Team up with Stitch or your friends in Kingdom Hearts: Birth By Sleep. This Kingdom Hearts game also has a multiplayer mode.
In Kingdom Hearts: Birth By Sleep players can don futuristic armor and meet in the Mirage Arena. Items earned while hunting heartless, nobodies, and unversed are carried over into the main game.
The multiplayer mode is designed for ad-hoc play, but you will be able to play over the Internet with Ad-Hoc Party.
Now for the bad news. Famitsu reports Kingdom Hearts: Birth By Sleep won’t wake up until January 2010.
