In August of 1986 Nintendo expanded their lineup of games with Metroid, a space-based action adventure video game for the NES. Now, over thirty years later, Samus returns to her original adventure on the NES Classic Edition, complete with all the original secrets and cheats from the original game. In this article we’ll teach you some of these secrets and even show you several passwords you can use to get missiles, energy tanks, and more.

How to End the Game Quickly

Stuck in a level or just need to go back to the password screen for a minute? You can quickly end a session in Metroid by pressing Start on the first controller. Then, grab the second controller and press UP and A at the same time. This will quickly pull you out of the game and toss you back to the password screen, where you can enter in new passwords and then continue playing.

How to Skip Kraid and Ridley

Don’t feel like fighting this boss duo? You can easily skip them. To complete this “glitch” or “hack” you’ll need to have made it far enough in the game to get the Ice Beam. Now, head to the room where the bridge needs to be formed and you’ll find Ridley and Kraid’s statues there. Before you enter the room, though, have the winged enemy chase you and let it hit you just as you enter the room. This will cause it to follow you into the room, where you can freeze it and use it as a stepping stone to jump across the gap, thereby allowing you to skip the boss fight with Ridley and Kraid.

Using the codes listed above you can change the game to make it play almost any way that you want. This also gives players a chance to play as Suitless Samus, which could previously only be unlocked by completing the game by a specific time. While we don’t recommend using all of these codes, some can be useful if you’re just looking to enjoy the 8-bit beauty of Metroid on the NES Classic Edition.
