If you have come to this page, then you need it. Reset occurs without third-party programs. So how do you reset a specific game's achievements on Steam? Read below.

⚠️WARNING!!! This can reset all achievements for the selected game on Steam or a specific achievement. It doesn't reset your in-game time, only achievements.

This does not remove the achievement from the game. It resets the progress of the achievement or all achievements in the selected game. This is done so that you can earn the achievement again.

This does not reset achievements from Origin, Blizzard, Ubisoft, Rockstar and other games that have the same achievements as Steam. It only resets achievements on Steam.

If the game has an additional launcher (such as Ubisoft, Rockstar, Origin, etc.) and has the same achievements separately from Steam, then the achievements on Steam are synchronized with the achievements of other launchers. That means that to reset achievements in these games, you need to reset achievements on Steam and in another launcher that runs the game. Otherwise, when you launch the game, Steam will synchronize the achievements from the other launcher and again count these achievements.

When you buy a game on Steam, it is automatically added to your game library. If the game has achievements, they are also added to your achievement statistics. If you reset the achievements in any game in your library, it will reduce the average percentage of achievements in your Steam profile.

If you reset achievements and they reset in the game but not in your profile, wait up to 1 day. The information should be updated in your profile.

I hope it helped. Good Luck!

If the reset achievements didn't work for you.

Method 1.
I think if the game has cloud saves enabled, Steam makes achievements cloud-based as well. So when you reset your achievements and then start the game, Steam checks the achievement file in the cloud and yours on your PC. If there is a difference, it downloads it from the cloud.

When you reset the achievement, turn off the Internet and launch the game in which you reset the achievement. When you start the game, turn on the internet again and then exit the game. The files in the cloud should be replaced by the files from your PC.

Method 2.
Select the achievements you want to reset and reset the easiest achievement as well. After that, you will need to obtain the easiest achievement again. The achievement file should refresh and overwrite.
