Easy Mode & Challenge Mode
For years, players of the Pokémon games have wanted a difficulty setting; Pokémon Black 2 and White 2 finally make this a reality. However, it has a twist. These modes cannot be unlocked at first, but rather require game completion first. However, that does not mean the game cannot be played immediately with it..
As the features are part of the Unova Link, you have the ability to send the modes to other players game utilising the game's IR port. As such, if you have a friend that has unlocked them, they can send it to your game so that you can play with them on. Once obtained, if you restart your save file, you will lose access to them again.
They are activated within the Unova Link menu and will run on the save file until deactivated.
Unlocked: Defeat Champion - Pokémon White 2
Unlocked: Defeat Champion - Pokémon Black 2
In addition to this, the Gym Leaders and Elite Four will have an extra Pokémon within their squads, and their other Pokémon shall have different movesets and hold items.
