Nintendo has announced that Overcooked 2 will be the next free trial in Japan for Switch Online subscribers. Members can play the game at no extra charge between December 7 and December 13, and, progress can be transferred to the paid version.
While this has not been announced for the west yet, going by past offers, this will come to the west a short while after. In the meantime, you can still access it right away, as long as you’re a Switch Online subscriber, by creating a Japanese Nintendo Account and accessing the Japanese eShop.
