Ya se sabe lo que dan los amiibo:
Samus Aran (Metroid Series)
Elon Reserve Tank (special ability recovery)
Metroid II Art Gallery (unlocked after beating game)
Metroid (Metroid Series)
Metroid Marker (tells you location of nearest Metroid)
FUSION Difficulty Mode (unlocked after beating game)
Samus Aran (Super Smash Bros. Series)
Missile Reserve Tank (missile recovery)
Concept Art Gallery (unlocked after beating game)
Zero Suit Samus (Super Smash Bros. Series)
Energy Reserve Tank (energy recovery)
Sound Test (unlocked after beating game)
Si esto quiere decir que solo se pueden desbloquear estas cosas con los amiibo, me parece bastante feo.
