# Hollow Knight: Analyze Save Completion Online Tool

> Analyze your saves. See precisely what you missed and where. See Completion %, locations (also Shards/Fragments), costs. 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. So I wrote a tool for that. It can also give an optional hint if stuck, based on the in-game progress.

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

If this is your first playthrough and you feel completely lost, I will give you a very slight optional hint which should point you in the right direction (no major spoilers). Hidden by default.

I will show you all individual Mask Shards and Vessel Fragments as well as locations and costs of every item on the list. Locations/costs are hidden by default if you don't want spoilers.

## How to use

* Use bloodorca's amazing [Online Save File Editor](https://bloodorca.github.io/hollow/) 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](http://reznortech.rf.gd/hollow-knight-completion/).

* 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 (❌).

All feedback/problems/wrong data are appreciated. Feel free to write them in the [Steam Discussion](https://steamcommunity.com/app/367520/discussions/0/2915472677711090083/) thread for the Tool or under the [Steam Guide](https://steamcommunity.com/sharedfiles/filedetails/?id=2209910193).

Currently only things that are necessary for Game Completion % achievements are shown. The tool doesn't show all the optional things, bosses, challenges, relics found, geo caches opened etc. that are not required for completion %.
