Must a Savior Die? — Red Dead Redemption Mission Walkthrough
Head to Luisa Fortuna, whom you have saved more than once in Red Dead Redemption, talk to her, and watch the cutscene.
She will tell you about her grief: her fiancé, Abraham Reyes, has been captured and is being held in El Presidio. You need to head north with Luisa as soon as possible. Upon arrival, you will see a large prison. Your task is to find a way to get inside.
Climb over the fence and take a sniper position. First, eliminate the executioner, as the execution has already begun.
The next step is the simplest — get rid of all the army soldiers who are shooting at you. After doing this, go down, free Reyes, and head with him to the river, where Luisa will be waiting for you. Along the way, you will also have to fend off the army soldiers. After handing the rescued man to the girl, you will receive +100 points to the Fame parameter.
