Only two endings reside in Metroid Prime Hunters, each of which you'll see depending on whether or not you face and defeat Gorea's second phase (see the bosses guide for more information).
|Only defeating Gorea phase 1:
The Oubliette explodes, without revealing the fates of either Samus or Gorea.
|Defeating Gorea phase 2:
Gorea is ultimately defeated, we then see Samus make a hasty escape from the doomed Oubliette along with her rival bounty hunters. The Alimbic Elders appear to an armourless Samus and offer their thanks before she leaves the star system aboard her gunship.
