Metroid Codes

Play as Samus with bonus weapons:
Enter JUSTIN BAILEY ------ ------ as a password to play as Samus at Ridley's Lair.

Super password:
Enter NARPAS SWORD0 0000_ _ _ _ _ _ _ _ as a password. Note: "_" indicates a space, and except for the letter "O" in "SWORD", the remaining characters are the number zero. You will start at the beginning of the game with unlimited life, unlimited missiles, and all upgrades. The word in this is "NAR PASSWORD". "NAR" is an abbreviation for the name of the person who designed the password system, Tohru Narihiro.

Alternate game:
Enter 999999 999999 KKKKKK KKKKKK as a password with no Varia suit and a different ending.

Super jump:
Hold Right on controller two and press A on controller one.

Quit game play:
Press Start to pause game play. Hold Up + A on controller two to display the current password.

Hint: Play as Samus without her suit:
Complete the first quest without dying and with all the items (ice beam as your gun weapon). Press Start after the credits have completed. If you have completed the game correctly, Samus will take off her suit in the ending. You will start with all your items you gained in the previous quest minus your missiles and suit in the next game.

Hint: Refill energy easily:
Go to a pipe that has enemies constantly appearing at ground level with no other enemies around. Just keep shooting and the enemies will fly into your bullets, leaving energy and other items.

Hint: Defeating Kraid:
Use the Ice Beam to freeze the center spike in mid-air as he shoots. Then, use your missiles to shoot the bare spot where the spike was located.

To defeat Kraid fast and easily, morph into a ball and start planting bombs all over him until he is defeated. To make this easier, you must get the Varia Suit and about three Energy Tanks.

Hint: Shooting walls and ghost walls:
In various parts of the game, you may find yourself blocked or cut off. You are either stuck or you can try shooting the walls around you. If you are lucky, one of the blocks will break. If it does, continue shooting until you cannot shoot further. Then, jump and try moving to the left or right. There is usually a ghost wall that you can go through. This trick is useful for gathering power-ups and finding secrets.

Glitch: Wall jump:
This trick requires the Morph ball Shoot a door to open it, then stand in the threshold until it closes again. You can then move slowly up the wall by pressing Up and Down rapidly. Alternately, if using a controller with a turbo feature, press B rapidly while tapping Down for the same effect. In some vertical hallways you can work your way up the hall. Once you are near the top of the screen, jump repeatedly to make the scrolling screen catch up to you. If you do not let the scrolling screen catch up to you, then it starts to go back down the hall, until you come back from the bottom of the screen. By going through the ceiling or floor of some halls, you can find some secret areas that were not intentionally designed. These places usually make no sense in terms of room layout, and often have no way out.
