Zero Mission is a well-made remake of the first NES Metroid game. Aside from the much-improved graphics (similar to the SNES Super Metroid), this new version includes welcome quality-of-life improvements over the original, such as a map and much more responsive controls, which are welcome additions. And, for the purists, once you beat the game, you'll discover that the original NES Metroid can be played from the options menu. This game is a great addition to the Metroid franchise.
