You can have one Pokémon out and walking with you in the Paldea region’s great outdoors.
When you have a Pokémon exploring with you in the field, you can use the “Let’s Go!” feature to send that Pokémon off in the direction you indicate. The Pokémon you send out then independently picks up items in the area and even has Auto Battles with nearby Pokémon.

What Are Auto Battles?

Auto Battles are a new way of battling that can be activated by using the “Let’s Go!” feature. Doing so will send out a Pokémon to battle wild Pokémon without needing orders from its Trainer. Your Pokémon can be sent into an Auto Battle against any wild Pokémon you see on the field, and it can even find Pokémon to engage in Auto Battles on its own.
When your Pokémon is out and engaging in Auto Battles, you can do what you want—stay by its side to watch over it, or try looking for items nearby. By defeating wild Pokémon in Auto Battles, your Pokémon can also earn items and Exp. Points!

Master using this new feature to explore every nook and cranny of the vast Paldea region with your Pokémon!
