>>5203967"They Will Hold Us Responsible" is a Metroid quest set immediately after Fusion. Instead of the Galactic Federation shrugging its shoulders and giving Samus a hi-five for discovering state secrets and destroying them, along with a vibrant and historically significant planet, without orders, they will be all up in her business trying to keep her silent. More silent than usual, anyway.
Could play out as lone hero against corrupt government. May end up being a start of darkness. We'll find out!
