This achievement can be earned in the chapter Intrusion.
I was really struggling with this achievement because I couldn't time it right. I knew you want to break the window when Conrad counts to 6 so you break the window when the thunder cracks, but other guides weren't working for me. So here's what I did: I counted in my head starting when he got to 5, then I button mashed
right when I thought he would get to 6 (which he did) to make sure I got it right, and the achievement popped.
NOTE: The reason I button mash
is because on two attempts Julia broke the window instead of Conrad. On a third, I was watching Powerpyx video, and Alex damaged the window on the count of 3, and they were able to break it on 6. So I tried it but Conrad broke it too early.
