I can't seem to get this to unlock.

Do you have to complete all 3 scenarios without dieing?

I've completed the first and 2nd (quest ones) without dieing and died on the third and when I finished no trophy.

I got it on van helsing 3 just by doing 1 scenario quest and it unlocked.

Do you have to have it on a certain difficulty? I've just been doing it on casual.

Anyway thanks to a help. I've been on this for hours.

Edit: I got I on casual. You have to do all 3 scenario missions without dieing. Part 3 you only had to do 1 mission.
