A Save Editor already exists for Factorio. With it, you can customise practically any aspect of the game, although it is a little difficult to use. Sometimes though, it might be easier to use Satisfactory mods instead which offer different types of cheats and ways of adding items into the game.
At the time of writing this guide, Satisfactory was in its early access. For that reason, there may be a few things different in this guide compared to your own game depending on future updates. If you’re interested, we’ve covered many more Satisfactory Guides here at PwrDown!
Install the Save Editor
Start by heading to the Satisfactory Save Editor GitHub. Download the latest version, found under the Releases section (the link above should take you straight there). You want to download the .ZIP file, which can be found under the ‘Assets’ section.

Once installed, open the ZIP file. It’s a good idea to have a program like Winrar or 7Zip which can manage ZIP files. Open it up, and extract the contents into a folder somewhere on your computer, then head to that folder.
Open a Save in the Editor
Hopefully, you will be in the folder where we just installed the Save Editor to. There’ll be a lot of files, but the only one we need is ‘SatisfactorySaveEditor.exe’, which you should open up.

From the top of the screen, choose File > Open. The program should open up a file browser, specifically to your SaveGames folder which is located at:
C:\Users\YOUR USER\AppData\Local\FactoryGame\Saved\SaveGames
If it didn’t, you’ll need to navigate to this location yourself. Choose the folder which has a long string of numbers and letters, this will be your account. Inside, there will be multiple .sav files which will likely consist of any auto saves and manual saves made. Select the save file you want to open.
Edit Your Save File
Now, this is where things may get a little confusing. You now have access to every bit of data that’s saved, and that includes a lot of variables that you’ll never need to access. You’re free to explore all these menus and mess around however you please.
For basic profile editing, choose File at the top of the screen, then ‘Jump to Tag’. Enter the following text into the dialogue box that shows up: Persistent_Level:PersistentLevel.Char_Player_C_0.inventory

This will take you straight to your characters inventory. On the right hand side, you can expand mInventoryStacks to see all the items you had in your inventory when this save was made. You can change the ItemType and NumItems to whatever you please, giving yourself new items.
In the top of the Save Editor, you can also use the ‘Cheats’ drop-down to select other options such as mass dismantle, create a crate full of items to give to the player, unlock all research, unlock entire map and more. When you’re finished, make sure to choose File > Save to have the changes take effect.
