While playing through The Last Story’s… uh… story you only control the Gathering power gifted mercenary Elza. The cooperative online mode lets players use other party members.
So, instead of protecting wizards, you can play as a wizard and cast spells. In an Iwata asks interview, Hironobu Sakaguchi joked people playing as mages may be asking other players why they aren’t protecting them. Online battles use a chain battle system where you can deal more and more damage by taking turns striking the enemy. Takuya Matsumoto thinks this system will up the affinity between players.
The battle royale mode, according to Sakaguchi, has a different atmosphere from the story mode for players to enjoy. Sakaguchi hopes players will show off their costumes during multiplayer fights.
The Last Story doesn’t have voice chat, but it does have a chat system. There are so many recorded lines in the Wii game, Mistwalker developed a system that lets players mash these together into custom quotes. Sakaguchi says in addition to conversations during event scenes, you’ll hear characters talk while you walk and before battle where the leader gives advice. There are many interesting lines to use, Sakaguchi says, which he wanted to let players use for online play. Matsumoto gave an example of Yuris repeatedly saying "father" and laughed after he mentioned it.
