The Nintendo Switch version of Naruto Shippuden: Ultimate Ninja Storm Trilogy will arrive in the Americas on the same day as the Japanese one. In both regions, people will be able to acquire the collection on April 26, 2018. That is when it will appear in the Nintendo Switch eShop. A European release date has yet to be confirmed.
As a reminder, the Naruto Shippuden: Ultimate Ninja Storm Trilogy contains three games and DLC costumes from the original games. It runs at 30fps, like the PlayStation 3 and PlayStation 4 versions of the games, at 1600×900 resolution in TV Mode and 960×540 resolution in Handheld or Tabletop Mode. Control options include one person using both Joy-cons, using the Joy-Cons in their grip and the Nintendo Switch Pro Controller. (You can not use a single Joy-Con to play the game.)
Naruto Shippuden: Ultimate Ninja Storm Trilogy is immediately available on the PlayStation 4, Xbox One and PC.
