Oh wow, kudos to you, I know that must’ve been crazy. I actually have a sorta similar Mirror’s Edge story.
For some reason that I can’t comprehend, I decided to try my hand at the “Test of Faith” trophy and simultaneously the “Pro Runner” trophy (beat the game on the hardest difficulty) in the same playthrough. Again, I’m not sure what possessed me to want to undertake such a challenge, but I actually did manage to get it done.
Whatever possessed me then must’ve came back for seconds, because interestingly enough, I did a very similar thing with Dead Space a couple months later–going for the “One Gun” trophy (beat the game using only the starting weapon), while also again going for the trophy for beating it on the hardest difficulty. Managed to do this one too, and somehow managed to not hate the game afterwards haha.
