>>716158571Thinking about the multiplayer, I liked Prime 2 version of it but if they're going to do something multiplayer with Metroid the best way would be to leave it out of Prime 4 and remake or have direct successor to Hunters.
Could have a tight campaign again, without the limitations, but the focus being the multiplayer.
Maybe do the roster Warriors style and have all sorts of characters from across the series duke it out.
Could have stuff like a Fed trooper or a Luminoth warrior. Though the specific focus on the hunters had it's own appeal.
