The release of Pokémon Let’s Go! Pikachu and Let’s Go! Eevee is fast approaching and a new trailer has been released to highlight features of the upcoming games. The games add the ability to activate special Partner Powers which are special attacks that can be used when a special icon pops up.
Pikachu or Eevee are able to use Secret Techniques, which seem to be functionally identical to the HMs (Hidden Machines) Surf, Cut and Fly.
In addition, a special Limited Edition Nintendo Switch has been announced that features brown and yellow Joy-Cons and artwork of Pikachu and Eevee on the dock. You can see the trailer for it below.
