Metroid for the NES is a beloved classic, and was re-released as an enhanced remake for the Game Boy Advance, called Metroid Zero Mission. This version of the game, built from Super Metroid for the SNES, is based heavily on the Zero Mission re-release and includes features from both. If you loved the original Metroid you are bound to love Zero Mission. The game has all the atmosphere of its forefather and enough modern gaming savvy to keep it fresh and interesting. Even gamers who had trouble liking the NES original are bound to find something to love in Zero Mission, as the game refines the formula making it accessible to newbies whilst retaining the depth in exploration and compelling action that veterans love. The cartridge is built and assembled in Canada using all-new components, including the cartridge casing. No donor carts were harmed in the making of this game.
