Launching alongside the upcoming Metroid: Samus Returns 3DS title will be a 2-pack of amiibo consisting of a bad ass Samus and Metroid figure. Translated from the Japanese Nintendo website, we now have a better understanding of what these amiibo will do in game. Better yet, the Smash Bros Samus and Zero Suit Samus will also be compatible with the game.
Samus Aran (the new Samus amiibo) – special reserve energy tank and will unlock a Metroid II art gallery after the game has been beaten.
Metroid – the Metroid Marker will identify the location of the nearest Metroid on your map and will unlock FUSION difficulty once the game is beaten.
Samus (Smash Bros series) – will refill missiles and unlock some concept art after the game is beaten.
Zero Suit Samus (Smash Bros series) – will refill energy and unlock a sound test after beating the game.
