Metroid Zero Mission


Metroid Zero Mission is a reimagining of Samus’ very first meeting with the Metroids. In this enhanced remake of her original NES adventure, Samus gets to use some of the abilities and weaponry she discovered in later games in the series to fight her longtime nemeses Mother Brain, Kraid and Ridley, as well as all-new enemies in both familiar and never-before-seen environments. Finally, the true story of Samus’ first encounter with the Space Pirates will be told…

Release Date


Metroid Zero Mission was a triumphant retelling of the original Metroid story, and the music was given a substantial update as well. Kenji Yamamoto and Minako Hamano consulted with Metroid composer Hirokazu Tanaka to ensure the music was true to the original. Most tracks have been extended, such as "Kraid's Lair", which adds an impressive choral section, though its change was not the most dramatic. "Norfair" received one of the biggest improvements, with a lilting flute and bubbling choir. "Ridley's Lair" also received a major overhaul, dumping the intensity of the original in favor of a slower and creepier ghost-filled corridor. Finally, there are two versions of "Brinstar".


Yamamoto-san also tied the series together aurally by integrating Metroid Primestyle Chozo themes, as well as a nice reference to the Super Metroid "Title" theme in the "Metroids Appear" cutscene. There are also remixes of "VS. Ridley""VS. Kraid""Spore Spawn", and "Space Pirates Appear", as well as two clever arrangements of "Wrecked Ship" from Super: the low and menacing "Crateria" and the jazzy, sneaky "Space Pirate Mother Ship".


However, the instrument selection is somewhat inferior to that of Fusion, owing to the different art style and the legacy of the original themes. Still, the soundtrack manages some fantastic bass, particularly "VS. Mecha Ridley" and the Japanese version of the "Escape Theme", and it also has excellent choral synths, such as those found in the "Ending" theme, and a nice organ with "VS. God of War". Overall, an excellent score and fantastic homage to the original. This soundtrack was created with VBA-M r956, with a -0.3 filter to closely emulate the actual GBA sound hardware.

What is Time Attack Mode and why does it exist?

Time Attack Mode was created as a way to have online leaderboards before the days of networked portable consoles. It was utilized in Japan only. What this mode does is after beating the game, an ID and a Password is generated in the Options menu, which allows you to manually register your time and item collection percentage into Nintendo Japan’s website. Nintendo had two different sections to this leaderboard too, one with partial item completion, and one with 100% completion, which they call “Perfect game.”

Nintendo recorded the top 295 imperfect game times and the top 316 perfect game times on their leaderboard. They also gave a free Samus-themed GBA SP away to the top contestants. The contest ran from June 14 – July 14, 2004.

#1 Imperfect game time:トロ(仮) – 0:28:09 (in-game time)

#1 Perfect game time: SA-X – 0:53:08 (in-game time)
