The game features the great role-playing adventure that Pokémon fans love, while expanding the quest to include awesome new features and locations.

The newest Pokémon adventure lets players battle, trade, collect and more, all without the need for connecting cables. Players simply attach the Game Boy Advance Wireless Adapter to their Game Boy Advance systems and communicate directly with one another. When visiting a special area (Union Room), connected players appear directly on one another's screens. Players who gather in a Union Room can send text messages directly to one another. Up to 40 people can share the environment and up to five people can buddy up at once to join a chat session and select pre-set messages to send, or type in messages of their own creation. Players can exchange game challenges, talk battle strategy or just shoot the breeze.
