According to the announcement of the game, it will cover the 4th shinobi world war arc until the episode right before its release. By my calculations this may cover the end of Itachi and sasuke vs Kabuto but that means the game will take an abrubt stop and wont cover the whole arc. I haven't taken into consideration any filler episodes or breaks between epoisodes so if any filler episodes or breaks are there even lesser part of the arc will be covered
