There's more to Pokémon Sun and Moon than a new region and monsters. Nintendo has revealed during its E3 live stream that the game will also introduce a four-player battle mode called 'Battle Royal.' Each trainer selects their preferred Pokémon and then enters the ring at the same time. On your turn, you can choose to target any of the three creatures in front of you -- this opens up new strategies as you focus on particular opponents and form uneasy alliances. Our only concern is the wait times -- four trainers mean it could be a while before you can select another attack.
