Bloodshore (EP)

There are some prerequisites to get the opportunity for this one.

First, you must choose to save Gav on the bridge.
Later, you will be hunted in the woods by Reah.

If you don't move, she will find you and kill you. But it will rewind and give you another chance.
Now, there will be only one option - "Move"
Don't make a decision and just let the timer run out
The achievement will unlock the third or fourth time you do this.

Here is a complete text guide for the game.

I suggest going into settings and turning Streaming Mode ON. This removes the decision timer, and lets you look up which choice to make.

If you have seen a certain scene completely, from the current decision until the next, you can skip through that section by pressing LB (RB might also work). I strongly suggest caution when doing this; pressing the button too many times will force a decision, and it may not be the one you want. That said, replaying certain sections will get tedious.

There are certain points were you will want to turn OFF Streamer Mode. I'll note when that happens.

This is as (plot) spoiler-free as possible. I've added spaces to show where scenes change.

Playthrough #1 - 560 GS


Playthrough #2 - 240 GS, 800 total


Playthrough #3/4 - 100 GS each, 1000 total


Hope this helps!
