Narpassword, or NARPAS SWORD, is a special password in the NES game Metroid. If you go to enter a password and type it in, it will spawn you at the start of the game, with unlimited health (you can still take damage, but the number in the 10s place will never change), unlimited missiles, all items and a glitch beam with a combination of the wave beam and ice beam.
If you plan on beating Metroid with the Narpassword password, you should get at least one missile container, because if you attempt to kill any enemies that drop missiles, and an enemy attempts to drop it, that will crash the game. However, you will be fine if you don't kill any enemies (the main problem is the metroids).
