The original Metroid is a timeless classic that was one of the first games ever to offer non-linear gameplay. Our strategy guide offers one way, out of the many ways through Metroid. There are no levels, just huge areas to explore. Our Metroid walk through is divided into small parts, each part continues where the last one leaves off, making it easy to follow along. We also uncover all the power ups that will upgrade Samus with new abilities and expansions. This Metroid walkthrough can also be used for the NES version, since both the NES and GameBoy Advance versions are the same game.
