i cannot understand how this is the last game of the trilogy.remember in the first part of the game where the admiral is talking about the network being down and you needing to deliver the vaccine to all the aurora units?in this game,you only give the vaccine to 1.what about the others?and also after you beat the game,it shows samus flying off into space and then another ship follows her.ALL the space pirates weren't on the pirate homeworld and phaaze,were they??does anybody else think there should be another metroid game?
