Samus wiped out the Metroids in Super Metroid. That extinction freed the X Parasites in Fusion. Now she runs from herself—the SA-X, at full strength.
In Super Metroid (1994), Samus destroyed the last Metroid—complete victory. Eight years later, Metroid Fusion revealed the cost. That extinction freed the X Parasites, and the research station became a hunting ground. The SA-X stalks the corridors with Samus's old Power Suit, her full arsenal from Super Metroid—every ability she once had, at full strength. Director Yoshio Sakamoto designed it around one insight: imitation is inherently unpleasant. Super Metroid let you explore freely. Fusion gives you mission orders and hallways where something stronger than you is walking.

About this game
Metroid Fusion (2002) is an action-adventure game developed by Nintendo R&D1 and published by Nintendo for Game Boy Advance. Eight years after Super Metroid, Samus returns in a mission-driven linear structure where she is hunted by the SA-X — a perfect copy of herself at full strength. The game sold over 1.6 million copies and marked the first 2D Metroid to tell its story through cutscenes and dialogue.
Key Features
Mission-based progression — Adam (an AI based on Samus's former commanding officer) gives orders and directs exploration. SA-X encounters — unpredictable moments where you must avoid a perfect copy of yourself. Flash memory save system — no battery replacement needed. GameCube connectivity — completing Fusion unlocks the NES Metroid in the game when connected to Metroid Prime via link cable.
The Story Behind
Super Metroid (1994) ended with Samus destroying the last Metroid — complete victory. Eight years later, Metroid Fusion revealed the cost. That extinction freed the X Parasites, and the research station became a hunting ground. Director Yoshio Sakamoto intentionally designed Fusion as the opposite of Super Metroid: free exploration became mission-driven linearity; environmental storytelling became explicit cutscenes. The game released in North America on the same day as Metroid Prime (November 18, 2002) — an unprecedented simultaneous 2D and 3D Metroid launch.
Tricks & Tales
The SA-X carries Samus's full Power Suit from Super Metroid — Ice Beam, Plasma Beam, Wave Beam, Super Missiles, Power Bombs, Screw Attack, and Space Jump. Director Yoshio Sakamoto described the design intent: 'imitation is inherently unpleasant.' The Japanese version includes three difficulty modes (Easy/Normal/Hard) and 11 different endings based on difficulty, time, and collection rate. The North American version has only one difficulty. Connecting Metroid Prime (GameCube) and Fusion (GBA) via link cable unlocks the Fusion Suit in Prime and the original NES Metroid in Fusion. Composer Minako Hamano was the first to score a Metroid game without Kenji Yamamoto's direct involvement — he served only as musical supervisor.
Collector's Guide
Region & Compatibility
The North American version released November 2002; the Japanese version followed in February 2003. Both use flash memory for saves. The Japanese version includes three difficulty modes and 11 endings; the North American version has one difficulty and fewer ending variations. Region-free modified Game Boy Advance systems play all regional versions.
Maintenance Tips
Metroid Fusion uses flash memory for saves — no battery replacement needed, ever. The cartridge is generally durable. Verify that the save function works by creating a save file and restarting the console. The Japanese version's value is driven by condition and the inclusion of the manual — CIB Japanese copies command a premium. Clean the cartridge contacts with isopropyl alcohol if you experience loading issues.
What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Metroid Fusion copies regularly.
Does Metroid Fusion use a battery for saves?
No. Metroid Fusion uses flash memory, which means your saves are permanent and never require battery replacement. This is one of the advantages of Game Boy Advance games over older Game Boy titles.
What's the difference between the Japanese and North American versions?
The Japanese version (released February 2003) includes three difficulty modes (Easy, Normal, Hard) and 11 different endings based on difficulty, time, and collection rate. The North American version (November 2002) has only one difficulty and fewer ending variations. Both versions use flash memory for saves and are functionally identical in core gameplay.
Can I connect Metroid Fusion to GameCube?
Yes. If you own both Metroid Prime (GameCube) and Metroid Fusion (GBA), you can connect them via the GameCube-GBA link cable. Completing Fusion and connecting it to Prime unlocks the original NES Metroid in Fusion (playable on the GBA). Completing Prime and connecting it to Fusion unlocks the Fusion Suit in Prime. This was part of Nintendo's 2002 dual-launch marketing strategy.
