For the first time in any Pokémon game, players will be able to fly freely around the game and battle wild flying Pokémon. In addition, players can find hidden areas, which include Mirage Islands that contain rare Pokémon and items.
In order to unlock this type of gameplay, you must have one of the games’ two legendary Pokémon, Mega Latios or Mega Latias. You can capture one of them about halfway through the game, a change from the original Pokémon Ruby and Pokémon Sapphire.
Pokémon Omega Ruby and Pokémon Alpha Sapphire will be available on November 21st in Japan, North America and Australia and November 28th in Europe.
