Kingdom Hearts Birth by Sleep: Difference between revisions

Like its predecessor, ''Kingdom Hearts 358/2 Days'', ''Kingdom Hearts Birth by Sleep'' contains a multiplayer mode known as Joint Struggle. While only a differently colored armored form of Terra, Aqua, and Ventus are playable, new abilities are usable only through this mode, and players can obtain bonuses for use in Story Mode. Up to three players can battle Unversed with customized names. They will also be ranked, this rank demonstrated by colored symbols that look like those Terra, Aqua, and Ven wear. A new world known as the Mirage Arena is also only accessed via the Joint Struggle. You can also play on the Command Board in multiplayer mode with a specific Mirage Arena game board.

As ''Kingdom Hearts Birth by Sleep'' is a prequel to the first ''Kingdom Hearts'', the Heartless have yet to invade and the Nobodies are yet to be created, so a new enemy known as the [[Unversed]] fills this gap. Ranging from very small [[Flood]]s to large monstrosities like the [[Wheel Master]], they attack Terra, Ventus, and Aqua along their journeys to countless worlds.  It's revealed that they are extensions of Vanitas.  Being born of the most pure, raw form of darkness, Vanitas is able to manipulate the negative thoughts and emotions of a being and embody it into an Unversed.
