 Uncharted: The Fourth Labyrinth
In October, archaeologist Luka Hzujak is found murdered in New York. Henriksen had been working with Luka and his wife Olivia, an employee at Phoenix Industries, researching labyrinths. However, Luka made a large discovery during his research and broke away from Henriksen and Olivia, which led to the archaeologist's murder.
Henriksen and Olivia make their way to the excavation site of the labyrinth of Sobek in Crocodilopolis, Egypt, the site of one of three ancient labyrinths crafted by legendary Greek craftsmen Daedalus. There, Henriksen and Olivia confront Luka's daughter Jadranka, more commonly known as "Jada", who is working with Luka's friends Nathan "Nate" Drake and Victor "Sully" Sullivan to unravel the mystery surrounding Luka's murder. With the help of excavation site manager Ian Welch, Jada, Nate and Sully have just discovered a hidden passage that talks of a lost labyrinth being on the Greek archipelago Thera, also known as Santorini.
Henriksen and Olivia follow Jada, Nate and Sully to the labyrinth of Poseidon, hidden beneath a fortress on Thera. Along with Henriksen's bodyguard Corelli and several hired guns, Henriksen and Olivia confront Jada, Nate and Sully in the labyrinth. However, they soon come under attack from the Protectors of the Hidden Word, a secret society set up to guard the mysteries of the ancient labyrinths. In the attack, Sully is dragged away by the Protectors. Jada and Nate chase after Sully to no avail, before returning to meet Henriksen and his entourage in the heart of the labyrinth. There, they discover that a mythical fourth labyrinth - the discovery made by Luka that got him murdered - exists somewhere in China. Henriksen offers Jada and Nate the chance to fly to China with him and his entourage; Jada and Nate reluctantly accept.
While flying to China, an employee at Phoenix Industries carries out research for Henriksen and informs him that "Diyu" - what is considered to be Hell in Chinese mythology - is said to be under the Chinese city of Nanjing. After being stopped briefly by customs officers at Nanjing airport for carrying weapons, Henriksen moves to meet up with a team of mercenaries who he has hired for protection in Diyu.
After advancing through the Ming Xiaoling Mausoleum and coming to the labyrinth known as Diyu, Olivia turns on Henriksen, revealing that Corelli and the mercenaries are loyal to her. Olivia orders Henriksen, Jada and Nate to be executed by the squad of mercenaries, but not before Nate is able to kill Corelli. Suddenly, the Protectors of the Hidden Word attack, which offers a distraction and allows Henriksen to escape with Jada and Nate. As Henriksen, Jada and Nate continue on through the labyrinth and are attacked by a small group of Protectors. Henriksen shoots and kills one of them, not knowing that it is a brainwashed Ian Welch. Sully is also among the Protectors, although Nate is able to stop Henriksen from shooting him too. After a short fight, Nate is able to subdue Sully and they continue on into the heart of the labyrinth.
In the heart of the labyrinth, Henriksen and the others are attacked by the "Minotaur", a man transformed into the mythical beast through a concoction containing the white hellebore flower. Henriksen shoots the Minotaur several times, before Olivia arrives with the final mercenaries. As the mercenaries battle the Minotaur, Henriksen makes his way into the treasure vault. In the treasure vault, Henriksen, Jada, Nate and Sully are attacked by the remaining Protectors, including the Mistress of the Labyrinth. Although Henriksen is able to subdue one of the Protectors, the Mistress approaches him from behind and slits his throat with a blade, killing him.
