Although the page link gives a 404 error when clicked, earlier today the Nintendo UK website listed Bye-Bye BoxBoy for the 3DS on their website with a release date of 23rd March.
The title was released in Japan under the name Goodbye BoxBoy! and is the latest iteration in the BoxBoy series. It’s also worth noting that when the title was originally released over in Japan, an exclusive Qbby amiibo was launched along side it. If the title does get released in the West, we may hopefully get the accompanying amiibo too.
As the title hasn’t been officially announced for release in Europe despite it’s listing, this information isn’t set in stone just yet. We’ll keep you posted with any updates.
