Arena Mode



Joint Struggle is the name of the new multiplayer mode said to be featured in Kingdom Hearts Birth by Sleep. In this mode, up to three players can take on the role of Terra, Ventus, or Aqua, the Keyblade warriors wearing their armor from the secret ending of Kingdom Hearts II Final Mix, rather than their usual gameplay attire.

Trivia

 * This is the first time that Terra, Aqua, and Ventus have ever been playable in their armor, let alone their normal in-game attire.
 * While in the Final Mix secret ending, the three Keyblade warriors' armored suits were a combination of browns, grays, and other dull colors. In Joint Struggle, however, Aqua's armor is blue, Ven's green, and Terra's red. The reason for the color change is currently unknown.
