Street Fighter 6 will add a new fighter to its single-player mode, World Tour. Elena, the Capoeira fighter, will be unlockable after completing Chapter 7-2 of the main story. To meet her, players must finish this chapter and then begin the “One Fateful Day” event in Metro City.
Starting the event will lead to a new Reniala Remains location where players can interact with Elena. As players increase their bond with Elena, they will unlock her signature moves and unique dialogue. This update is set to release on June 5 for PC (Steam), PS4/PS5, and Xbox Series X|S.
