Words cannot describe how much I love this game. These graphics could very well be the best graphics in a game to date (please don't attack me Xbox fanboys), the sound is perfect, the music is eerie, the action is buttery smooth, the game is lenthy in a good way, it's challenging but not frusterating, it's so deep it's scary... I could go on, but you get the picture. MP2 has done the impossible... it has topped the original's perfection.
From start to finish you will be glued to whatever you happen to be sitting on at the time (until you face one of the ten-story bosses in which case you will leap off it). It begins simple enough, the Federation has lost contact with one of it's ships, and has called in Samus Aran to investigate. Right off the back you know something is wrong... the bodies of countless troopers a strewn about, and reading their logbook entries will put into perspective how horrible their deaths were. You also encouter a dark figure early on that looks suspiciously like you... I won't spoil it for you, but anyone who beat the original with 100% completion will know what I'm talking about. And of course, in traditional Metroid fashion, you will lose nearly all your equipmant early on. How, you ask? Well that brings up a whole new element... a dark world. You see a long time ago... well, I won't give away the story, so let's just say their are two races; the Luminoth-good-light world, and the Ing-bad-dark world at war with each other, and you visit the dark world for a brief time early on only to have the Ing rip away alot of your gear. The two worlds have initially the same layout, to further the impression that this is just one planet existing in different dimensions. The dark world is incredible, a clausterphobic nightmare whose very atmosphere is poisonous, and Samus must stay within the saftey of a light zone generated by various crystals and beacons that the Luminoth use throughout the war (you also see the bodies of many brave Luminoth warriors strewn about both worlds). This game is flawless. It's worth the price of a Gamecube just to play this masterpiece of a game. Gamecube owners need not be jealous of Halo or GTA... you've go Metroid Prime 2: Echoes.
