How to learn the difficulty level of campaign

[onur.dagci]

Hi everyone!

I had started this game a few years ago and had played half of the campaign. I still have those save files. I am trying to understand the difficulty level of the campaign, is there a way to do this? In other words, I have save files from a few years ago but don't remember what difficulty level I was playing at. Is there a way to see what the difficulty level for these save files are (through game UI or maybe even opening the save files in a hex editor or something?)

Thanks for your help in advance!

PS> I have included a save file in case someone can load it to find a way to understand its difficulty level.
