The Metroid Marker is an unlockable Map feature in Metroid: Samus Returns. When the Metroid amiibo is tapped on the Nintendo 3DS, a small Metroid larva icon will display on the Map, showing the nearest Metroid. This can point Samus in the correct direction, aided by her Metroid Radar, which begins to beep as she gets closer to another Metroid. The amiibo will only reveal the location of one Metroid at a time and must be tapped again for more markers. Without the Metroid Marker, the only in-game hints as to Metroid locations come from interacting with Chozo Seals. They lead Samus to Metroid Husks, and from there she will have to continue tracking the area's Metroids.
