Well this has been a question of mine for some time now....which people have just neglected.....and it was what will happen to samus in Metroid Prime 3 Corruption when she gets phazon corruption from Dark Samus....well my question was finally answered.....
Phazon's Powers: The game also incorporates a new system involving Phazon. If you fill Samus' Phazon supply to a certain level, Samus will temporarily go into hyper mode, a state in which she can pull off incredible feats. On the flip side, if she exceeds the maximum Phazon level, she'll perish. Also, for the first time in the Metroid series, Samus' ship will be used in active game play.
i think that sounds pretty sweet! no?
