Uncharted 4 : A Thief's End | Chapter 2 : Infernal Place 1080p PC Ultra Gameplay Walkthrough

Infernal Place is the second chapter of Uncharted 4: A Thief's End.
After the orphanage flashback, the time-frame goes to 2001, six or five years before the events of Drake's Fortune.
In a Panamanian prison, Nate is fighting Gustavo, another inmate. The fight has garnered the attention of the other inmates who are in support of Gustavo. As Nate gets the upper hand in the fight, Vargas, the prison's warden, and other officers break up the fight. Nate and Gustavo are separated and Nate is thrown into solitary.
Sometime later, Nate is taken out by Vargas and is taken outside by an old Spanish prison tower. Vargas takes off his handcuffs and demands a cut of whatever Nate hopes to find. He then reveals that he knows about Nate's, Sam's, and Rafe's true intentions for bribing their way into the prison. Vargas opens an envelope given to him by Rafe and reads the letter inside written by Joseph Burnes, Henry Avery's first mate, who was imprisoned in the highest cell of the prison tower Nate and Vargas are looking at. Nate dismisses Vargas' demands, climbs the tower, and enters Burnes' cell.
The cell walls are marked with zodiac signs and stones scribbled with roman numerals. The letter helps Nate pinpoint the correct zodiac signs and roman numerals used in a puzzle, and hidden behind a stone is a hollow and broken cross engraved with the Latin inscription Digna factis recipimus. Nate tucks it away, climbs down the tower, and meets with a waiting Vargas. Nate hides the cross from Vargas, telling him he found nothing inside the cell and convinces him to let Nate talk to his brother Sam. Joined by Rafe, Nate tells him and Sam that Vargas wants a share but Rafe dismisses this and asks if Nate had found something in the cell. Nate shows them the cross and reveals that the person on the cross was St. Dismas and not Jesus, which leads Sam to conclude that the cross is pointing them to a cathedral in Scotland named after St. Dismas, where Avery was last sighted and purportedly buried. Before the trio can escape, they are confronted by Gustavo and his allies, and a fight ensues.
Just as Gustavo is about to kill Nate, Vargas arrives and subdues Gustavo. The other guards tackle the trio and Gustavo's allies and Vargas discovers the cross. He orders the trio to be left with him in his office. Just before he executes Nate for his deception, Rafe renegotiates with Vargas and they settle on a quarter cut each. Vargas accepts the deal, but Rafe stabs him to death causing Vargas to fire his gun. Nate and Sam are alerted to Rafe's aggression and they all flee just as the gunshot alerts the guards of the entire prison.
Nate, Sam, and Rafe run through the prison, escaping gunfire. A roof then collapses, causing Nate to be left behind, but is then joined by Sam as they are cornered by guards. Nate and Sam reunite with Rafe, who leads them to a boat left by Vargas outside the prison walls below the adjacent lighthouse. Nate and Rafe reach the prison walls, but before Sam can scale them, he is shot thrice and falls unconscious down into the prison below. Nate, who tried to help Sam up, becomes distraught over Sam's death. Rafe tries to convince him that he's gone, but flees without Nate. Accepting his loss, Nate recovers and joins Rafe and they jump off the prison walls and into the sea below.
