The Nintendo eShop listing for Pokémon Let’s Go Pikachu and Let’s Go Eevee has reiterated several tidbits about the upcoming duo of Pokémon games. They support gameplay for one or two players on the same console. Inputs can be performed via a single Joy-Con or using the Poké Ball Plus. Up to two separate players can play together online or locally. Touch screen controls are featured to a certain capacity in handheld mode, where throwing Poké Balls is performed via touch-screen gestures to catch Pokémon. In addition, the listing reconfirms that Pokémon Let’s Go Pikachu and Let’s Go Eevee do not support backups via Save Data Cloud.
