FET is currently the go to editing tool for FIFA 21, FIFA 22 and FIFA 23.
Based on Frosty Tool Suite, this tool is more dedicated to the FIFA series.
The tool comes with two different softwares:
The powerful Editor can be used to create mods, with the ability to import, export, and view many files including Textures and Meshes, with an incredible amount of other features to help you along the way.
You can use the Mod Manager to import and apply mods made from others (or yourself) made by the Editor, and has the power to play with multiple mods at the same time.
Please note that the ALTERNATIVE mirror is the link for the Mod Manager!
