Map Completion

Unlike other video games of this genre, you only need to find all the collectible items of an area in this game for it to be considered completed. You do not need to visit every single tile of the map, nor do you need to Scan Pulse Register the entire map. And don't be misled by the little triangle next to an area's completion rate, as it only refers to how many pins you have placed on the map. Go for the Collectible Items, don't worry about all the rest. You will receive a Chozo Memory for each Area you complete entirely.
