Indie RPG Squids Odyssey will become first Nintendo release with cross-buy functionality when it launches on 3DS later this week—though only in Europe, and only from 3DS to Wii U.
Developer Game Bakers informed Siliconera that the cross-buy support only works if someone purchases their strategy-RPG on 3DS, thus gaining access to the Wii U version. Wii U purchases do not unlock the 3DS version.
As for why this half-cross-buy functionality is only in Europe, according to Game Bakers the company said that Nintendo of America “could not support this operation yet.”
Squids Odyssey launches on 3DS July 3 in Europe. The Wii U version launched in North America last month, on May 22. It originally debuted on iOS devices October 2011.
