100% Completion

100% Completion refers to having mastered all aspects of a title. The Permanently Missable Items Article is useful to those undertaking this challenge. Like the Three Heart Challenge, and Speed Runs 100% Completions are an optional challenge for The Legend of Zelda series fans.

To brag of having a 100% Completed file, one must have all Heart Containers, Weapon upgrades, Items, and Collectible items such as Ship Parts. Unlike the Metroid Series, the Legend of Zelda series thus far has no in-game rewards such as alternative or lengthened endings for the feat. Although finding every last collectible is difficult in its own rights, doing so makes gameplay easier than Speedruns, Minimal Completions, and Three Hearts Challenges.
