Nintendo has been keen on making certain features within their games accessible only via the NFC connection with the appropriate amiibo. Now, we’ve learned a key feature in Metroid: Samus Returns is locked behind amiibo DLC.

The game will have both the Fusion Suit for Samus and the game’s hard mode locked behind the Metroid amiibo. Here’s the full breakdown of the amiibo and what each one unlocks:

• Metroid amiibo: Unlocks Metroid Marker, a tool to help you find nearby Metroids. In addition, it will also unlock Fusion Mode, a new mode that offers increased difficulty and features Samus in her Fusion suit. Note that Fusion Mode will only be available after finishing the game at least once.
• Samus Aran amiibo: will unlock an Aeion reserve tank allowing you to recharge your Aeion energy. In addition, it will unlock a unique Metroid II Art Gallery once the game has been completed at least once.
• Samus and Zero Suit Samus amiibos: These two are from the Smash Bros. series. Samus will unlock a reserve missile tank, and after completing the game, an additional in-game art gallery. Zero Suit Samus will unlock a reserve energy tank, and after completing the game, a selection of music.

Nintendo confirmed to Eurogamer that all of the above content is only available if you own the appropriate amiibo.

Metroid: Samus Returns is launching for the Nintendo 3DS on September 15th.
