Getting plat in bloodborne before dlc
I did four stores loud in a suit with no downs.Gave this a second thought, and I think High Octane (finish the Car Shop heist on Death Wish difficulty) from Payday 2 was the most difficult achievement I ever obtained. Not sure I'd call it the most satisfying, because back when I did this for the first time, there was no achievement for it (despite the fact that it was actually a lot harder than it is now and I did it solo, ain't that a ). I had to do it again to actually get the achievement, and when that happened I just called in 3 friends and rushed it.
I think it's safe to say you had a bad time.Beating the final boss of Undertale's Genocide run in just 10 tries. I wouldn't call genocide "satisfying" though.
