How to Do a True Reset in Undertale on PC, Mac, Console

One of the things that makes Undertale such a unique and ground-breaking RPG is its multiple endings. If you are trying to get all endings, you can reset your save data in the game's menu. This will erase most of your player data. However, some data is retained from the previous game and will be referenced in subsequent games. The only way to erase this data is to perform a true reset. A true reset can be performed in-game, as well as by manually deleting the saved data on your computer or console. This wikiHow article teaches you how to perform a true reset in Undertale.

True Reset in Undertale

The True Reset option becomes available in the game menu after you complete a True Pacifist route through the game. However, this does not remove the Soulless state from a Genocide playthrough. To truly reset Undertale, you need to manually delete the save files on your computer or game console.

Complete a True Pacifist route to unlock True Reset. To be able to complete a True Pacifist route, you must first complete a Neutral route. Once a True Pacifist run-through of the game is completed, the option to select True Reset will be unlocked in the game menu.^{[1]

Select True Reset in the game menu. If you have completed a True Pacifist run through of the game, you can select True Reset from the game’s menu. However, not all data is deleted and reset. If you have completed a Genocide route through the game, the post-game Soulless state is not erased, and all future endings are affected by it. In other words, an in-game true reset is not really a true reset. You will need to manually delete the game data to perform an actual true reset, as outlined in one of the other methods below.^{[2]

On the menu, it doesn't let you change your name; it keeps your name but resets only your progress. A true reset resets the whole game - name and everything.

Be mysterious, yet have great charisma. Make yourself appear to have great power, yet don't show it unless it is necessary.

I can't find the AppData. I'm on a Windows, it isn't under the user, and I've checked every other user.

In your User's folder, look at the View tab of your Windows Explorer. At the "Show/hide" section, make sure the "Hidden Items" checkbox isn't ticked. If this still doesn't work, follow these steps: 1) Open "Command Prompt". 2) Enter the string of text below: attrib -s -h C:\Users\myusername\AppData The command above would remove any attributes set on this folder that could hide the folder.

Tips

Once you have gotten to this location, it is advisable to keep a shortcut on your desktop because it is quite tedious to navigate back every time you need to access your save file.

If a new player is going to play the game on your computer, you might want to move your save file to keep the experience as unmodified as possible.
