The first Trine came to Switch a couple of months ago. Its two sequels are also planned for the near future, with the currently-in-development fourth title on the way.
Additionally, just a couple of days ago, Trinelogy was rated for Switch by PEGI. While we technically don’t have confirmation on what this is, it’s likely a bundle of the first three Trine titles as this product is available on Steam. What would be interesting to see is if Frozenbyte offered a physical version or if it’s only a digital release.
Frozenbyte has not yet provided release dates for Trine 2 and Trine 3 on Switch.
