A save editor is a third-party software tool that allows you to modify your SaveGame file. In the context of NFS Heat, this tool lets you manipulate raw data that the game normally locks behind progression walls.
While NFS Heat does not have a robust anti-cheat for single-player progression, using save editors to gain an advantage in online races (like instantly getting Ultimate+ parts) is generally frowned upon by the community. nfs heat save editor pc work
