Nintendo has been particularly active with updates across its Nintendo Switch 2 lineup. Today also saw patches roll out for Pokémon Legends ZA and Donkey Kong Bananza, while Donkey Kong Country Returns received a notable update yesterday that added Dixie Kong.
We’ll continue digging to see if anything else is tucked away in this update and will keep you posted on future patches for Mario Kart World.
