Item description:

I fixed/updated this save to earn all 3 difficulty trophies.
It's possible other saves don't work because there is a checkpoint right before a cutscene
and/or an update changed the format of the game.

Anyway, when I used the save on this forum, I hit Rusume on the last War Story, but there would be a loading
screen which eventually returns you back to the Act menu.
To fix this, I choose TIRAILLEUR - FRATERNITE OU LA MORT, and Restarted it on Hardcore difficulty,
and played it to the end.

After Resigning my save, Resume on the mission I mentioned above.
The save I have provided is at the checkpoint after destroying the 2 trucks, but before clearing the enemies
in front of the castle gate. This part is easy. Kill about 15 enemies using a sniper from a distance,
but watch out for the Flame Thrower enemy and the enemies operating the Flak 38 Cannon.
After this part there are 2 cutscenes and some movement in between and you won't have to worry about dying.
