Like the Generation IV games, Black & White include a variety of Wi-Fi features, some old and some new. Outside of the standard battle and trades, this page will detail all the new WiFi features of the games.
The Global Terminal makes a return within Black & White. However, rather than being in an isolated building in one city of Unova, the Global Terminal is now accessible through an area in the Pokémon Centres everywhere in Unova. The Global Terminal this time only has 2 features.
In addition to this, you also have the ability to upload your save file to Nintendo's servers. With this, you can then access a site they'll have and play games on their site which will have effects on your game. >One of the new features within Pokémon Black & White is the Pokémon Global Link. This feature allows you to upload your save to the Internet to access a specific website in order to get features and Pokémon in your Black & White games. This is hooked up by using the WiFi option on the C Gear which will allow you to sync the game up with the Global Link website. With this, you can send Pokémon to the Dream World, receive Pokémon and items from the Dream World, send your Random Match statistics and receive new skins for your Pokédex and C Gear.

Double Battle - Use 4 Pokémon
