Metroid - NES - longplay & ALL endings
2This was the first installment in the Metroid series, it was originally released in Japan for the Family Computer Disk System in August 1986. North America received a release in August 1987 on the Nintendo Entertainment System in the Game Pak ROM cartridge format, with the European release following in January 1988.
Its varied endings for fast completion times made it an early popular title for speedrunning. It was also lauded for being one of the first video games to showcase a female protagonist.
In Japan, the Disk Card media used by the Famicom Disk System allows players up to three different saved game slots in Metroid, similar to The Legend of Zelda in the West. Use of an internal battery to manage files was not fully realized in time for Metroid's international release. The Western versions of Metroid use a password system that was new to the industry at the time, in which players write down a 24-letter code and re-enter it into the game when they wish to continue a previous session. Codes also allow for cheats, such as "NARPAS SWORD" and "JUSTIN BAILEY".
Best Ending - acquired by playing for under an hour. Samus cannot be played in this form.
Good Ending/Suitless Unlock - acquired by playing for under 3 hours. Pressing start at the end of the credits will start a new game with Samus in this Justin Bailey suit.
Neutral Ending - acquired by playing for three to five hours. Worthy of note is that Samus' hair is a lighter brown than other Metroid endings.

Worst Ending - acquired by playing for five hours with Suitless Samus or ten hours of normal gameplay.
