Metroid Detector



The Metroid meter is a technology exclusive to Metroid II: Return of Samus. It is used to detect the number of Metroids remaining on planet SR388. Whenever Samus Aran kills one, be it an Alpha, Gamma, Zeta or Omega, the meter will scramble for a few seconds before it decreases the number by one. By default, the number is thirty-nine Metroids, however, when Samus is approaching the Queen Metroid the meter raises up to nine. Strangely, when the Metroid hatchling is born, the meter does not raise up to one. This could be due to an error in the code, the hatchling's imprinting of Samus as its mother or it was never scripted at all. Counting the hatchling, the meter totals forty nine Metroids throughout the game.
