Theater Mode (alternatively referred to as Theatre) was a mode in the Tekken series until Tekken 6. This mode features every characters' prologue and epilogue. This mode can be unlocked after Story Mode is beaten once.
Until Tekken Tag Tournament 2, the stage music could also be played in its own music player, similar to the remastered Tekken Tunes feature now present in the game. Also, this mode is now tagged simply as Gallery.
