Hollow Knight: Analyze Save Completion Online Tool

Analyze your saves. See precisely what you missed and where. See Completion %, locations (also Shards/Fragments), costs, Game Statistics. I even designed spoiler-free hints based on your progress, if you are completely lost.

General info

Hollow Knight doesn't have a game completion list. There is no way to easily check what specific things someone forgot to do for full 112% Game Completion. There are no Game Statistics as well. So I decided to write a tool for that.

Inspirations: discussions on the forum, KayDeeTee and bloodorca's Save Editors, programming learning, Elderbug.

Steam Guide

More info with features and visual previews can be found in the official Steam Guide for the Tool.

How to use

• Use bloodorca's amazing Online Save File Editor to decode your Hollow Knight user*.dat save file into text.

• CTRL+A (Select All) inside the text box after decoding the save. CTRL+C (Copy) to copy the whole contents inside the text box. Be careful not to copy the whole webpage! Only the text inside the text box.

• CTRL+V (Paste) the text data inside the text box on the Tool's webpage.

• Click "Analyze Text". If the copy-pasted data was correct, you will see your Completion %, Play Time, and a whole list of things you have done (✅) or not yet done (❌).

Hollow Knight Save game locations

Windows

%USERPROFILE%\AppData\LocalLow\Team Cherry\Hollow Knight\

Linux

~/.config/unity3d/Team Cherry/Hollow Knight/

macOS

~/Library/Application Support/unity.Team Cherry.Hollow Knight/

Filenames

user*.dat — main save file. Where * is a number between 1 and 4, and it is the appropriate save slot inside the game. user*.dat.bakX — backup save files. Where X is a number in ascending order meaning how many backups were made during the whole playthrough of that save. The higher the number, the more recent the backup. There are usually 3 save backups at one time, older backups are deleted.
