What is Metroid Fusion?
The hunted becomes the hunter’s double: a linear, haunted Metroid about being prey.
Metroid Fusion (2002) launched in North America on the same day as Metroid Prime, the 2D and 3D lines reborn together. R&D1 built it, Sakamoto wrote and directed it, and it is deliberately the opposite of Super Metroid: a station, a handler, a locked map, and something wearing Samus’s old suit hunting her through it.
THE INVERSION
What Fusion changes
The Fusion Suit
Attacked by the X parasites, Samus survives only through a vaccine made from the baby Metroid’s cells. The suit is surgically reduced and regrown: part armour, part organism, weak to cold like the creatures she exterminated.
The SA-X
The X copy her discarded suit parts and become the SA-X: a full-power Samus with no conscience, the game’s true monster. Fusion’s stealth is not scripted horror; the SA-X simply outguns you for most of the game.
Adam
Orders arrive from a commanding computer Samus names Adam, after her dead CO. The mission structure gave Fusion its guidance and its argument: how much of a Metroid game is the wandering?
The numbers
1.39 million copies and a 92 on Metacritic: the experiment was received as a triumph. R&D1 itself was folded into another division the following year, making Fusion the old studio’s last Metroid.
