It’s a mechanical gameplay flow, almost cruel in how it reduces the species to a dwindling statistic.

Samus finds and kills every Metroid on the planet as a number on a hit list ticks down at the bottom of the screen. Out of every game in the series, Metroid II is the one that most heavily leans into the bounty hunter premise. She accepts without hesitation and hubris ensues. After another series of failed missions (as we quickly realize, the Federation isn’t very good at its job), Samus is once again called to kill every single Metroid remaining on SR388. The situation escalates in Metroid II: Return of Samus, as the Galactic Federation determines that the only way to ensure the Metroids can’t be used as a biological weapon is to drive them to extinction. Samus’ decision to take that job sets off a complicated chain of events that puts both herself and the galaxy at risk. If these instances of hardline copyright law adherence are any indication, it's only a matter of time before the Japanese publisher takes legal action on this newest development in the emulation world.Samus Aran’s true archnemesis is Samus Aran. However, Nintendo does not share this same viewpoint on the medium, and has singlehandedly taken down websites that offer bootleg ROM files through litigation in the past. Much of the emulator community is rooted in preserving old video games that are no longer available for public consumption, with many of these games including classic Nintendo titles that are either unavailable for purchase, or extremely valuable (as noted by Game Rant). Other users have embraced the breakthrough, with the general consensus among them being that video game emulation is inevitable.

On Yuzu's post - which also included a download link for the file - some commenters have suggested that making 'Metroid Dread' available for emulators can hurt the game's sales numbers, thus giving longtime 'Metroid' fans less of a case to make when clamoring for future sequels.
