Gametrailers has a new teaser trailer up for Metroid Other M
. In it Samus Aran reflects on her younger years, when she'd just left her adoptive Chozo homeworld and enlisted in the Galactic Federation military. It looks like she had a falling out with her commanding officer, Adam Malkovich.
Adam is notable for sacrificing himself to save Samus. I always figured that this happened while Samus was in the military, and his death prompted her to go rogue as a bounty hunter. Now we know that Adam is alive and well as recently as the events of Other M, so his sacrifice will likely take place in that game, and lead right into the events of Metroid Fusion
. Apparently Samus left the military because of a disagreement she had with Adam, something she seems to regret in this trailer.
