Metroid: Samus Returns Nintendo 3DS Theme

The Metroid: Samus Returns Nintendo 3DS Theme is a digital reward exclusive to My Nintendo, Nintendo's loyalty program. Based on Metroid: Samus Returns, the theme costs 20 gold coins and features Samus Aran in the background of the top screen, while the background of space is featured on the touch screen. The Theme of Samus is heard when using this theme, and sound effects from Samus Returns are also used. On startup, and when opening the 3DS from Sleep Mode, Samus Aran's Appearance Fanfare is heard, before the Theme of Samus resumes. The theme is redeemable once, and the offer will expire on Oct. 16, 2017.
