To run an FTS mod, you typically need three components usually bundled in a single .zip file or provided as separate links: The application file to install the game. OBB Data: High-quality graphics and gameplay data.

Copy the folder inside the OBB folder and paste it into Internal Storage > Android > obb .

Open the APK file and install it, but do not open the game yet.

If you have an existing version of FTS, back up your current data folder to save your career progress.
