Chapter 14- Navajo
On the second night you'll go outside to investigate the strange noises and goings on. Firstly head towards the rock just out of shot on the left hand side of the screen. After that you have to move Jodie in the right direction using R3 depending on what direction she has started to move in when you go into slow motion.
I failed this on my first playthrough on the hardest setting. But I found out on my second playthrough that rather than just reading what direction Jodie is moving in you get a directional arrow telling you which direction to push R3 in. I found this a lot easier and had no problem unlocking it on the easier setting.
So if you're struggling on hard, do your second playthrough on easy.
