Metroid Zero Mission is a perfect remake. It takes the base of the original metroid and takes everything learned from super and fusion to create the definitive version of samus's first adventure. The games controls are ripped straight out of fusion making it the most fluid metroid game in the series at the time while also keeping the focal point of the original game of taking down ridley and kraid to fight mother brain. But the developers didn't just stop at improving the controls the environments are massively improved as they are made far more distinct than in the original with new power up's to find all over the place. The game also adds some of samus abilities from later games into this one making it feel just as much a sequel as it is a remake. There are new areas to explore in the game to adding even more exciting content to this already great package. The boss count has been increased to with some bosses coming out of nowhere adding to the tense atmosphere that metroid games have always created. The soundtrack is remastered beautifully with kraid's lair being a particular banger and new areas have songs that fit right in with the tunes from the original game. The game has a new epilogue that puts you in a unique scenario that acts as the cherry on top of this stellar cake. Zero Mission makes the original metroid redundant besides as a history lesson as it improves on everything the archaic original accomplished and piles more in. Exploring metroid 1 Zebes has never felt this good truly a masterful remake.
