Looks like Space Pirates weren't her only enemy. Samus now has the Preator Suit from DOOM. Her arm cannon has turned into a mini BFG, and she's taking care of demons now.
Warning: If you are now thinking about playing the game DOOM, it is an M rated game. Just a warning. Don't play it if you are under 18. FYI, it is actually spelled DOOM, not Doom, so it's supposed to be like that. Still taking suggestions.
