Metroid: Zero Mission is a retelling of the original Metroid's story with a couple of new plot twists and updated gameplay.
This movie improves on the previous attempt by the same author by 28 in-game seconds and 34 seconds of real time. The time saved comes from more optimized movements and a few minor tricks, but mainly from a greater understanding of RNG in the game.
The in-game clear time is 0:20:59. The item collection rate is 20%.
