LET'S PLAY THE EVIL WITHIN 2 WALKTHROUGH GAMEPLAY CHAPTER 15 - THE END OF THIS WORLD (NO COMMENTARY)

Three years after the events of the first game, Sebastian Castellanos (Marqus Bobesich / Hiroyuki Kinoshita) has left the Krimson City Police Department, haunted by his experiences at the Beacon Mental Hospital. His only child, Lily (Kiara Gamboa / Sakura Sakai), supposedly perished in their house fire, and his wife Myra (Elizabeth Saydah / Rika Fukami), unwilling to accept her daughter's death, abandoned him. This, coupled with his trauma, results in Sebastian descending into alcoholism. Drowning his sorrows in a bar, Sebastian is approached by former partner and Mobius agent Juli Kidman (Meg Saricks / Yūko Kaida), who reveals that Lily is still alive. Sebastian is brought to a secret Mobius facility against his will, where he meets the head of the facility named the Administrator (Richard Neil / Jin Yamanoi). The Administrator explains that Lily is being used as the Core for a new STEM system to simulate an idyllic American town called Union. However, Mobius lost contact with Lily and their agents inside Union, and they have lost control over the simulation. Sebastian reluctantly agrees to help and is plugged into STEM.

Upon entering Union, Sebastian discovers the town has turned into a nightmare realm where all of the inhabitants were either killed or mutated into monsters. In addition, Sebastian witnesses a mysterious photographer with supernatural powers hunting down and murdering Mobius operatives. He manages to find surviving Mobius personnel Liam O'Neal (Jesse LeNoir / Takuya Masumoto), Yukiko Hoffman (Ying Hsiao / Mayumi Sako), and Julian Sykes (Hari Williams / Tōru Sakurai), who help him in the search for Lily. As Sebastian follows her trail, he learns that she has been kidnapped by the photographer Stefano Valentini (Rafael Goldstein / Setsuji Satō), a serial killer obsessed with photographing people at the moment of their death who managed to infiltrate Union. Stefano reveals that he had originally kidnapped Lily under orders from another party, but decided to keep her for himself to exploit her powers as the Core. Sebastian fights and kills Stefano but before he can rescue Lily, Myra appears and takes Lily away. Sebastian finds himself transported to the interior of a mysterious stronghold-like area, where he is approached by Father Theodore Wallace (Ron Sewer / Tesshō Genda), who attempts to convince Sebastian to join him to seize Lily from Myra since Stefano betrayed him. Sebastian refuses and is banished to a forest outside Union where he meets with Mobius operative Esmeralda Torres (Crash Barrera / Tomo Muranaka). Upon reaching her safe house, Torres reveals that she, Kidman, Myra, and Theodore had conspired to break Lily out of STEM and destroy Mobius from within via their chip implants. However, the plan went awry when Theodore became mentally unstable and decided to kidnap Lily for himself.

Seeing Theodore as the most immediate threat, Sebastian goes to confront him, but is forced to kill a brainwashed Liam. Upon reaching Theodore, Sebastian is immediately incapacitated when Theodore uses Sebastian's own lingering guilt against him and he falls unconscious. Sebastian is visited by a vision of Myra, who assures him that what happened to Lily was not his fault and that he should focus on saving her. When he wakes up, he finds out that Esmeralda had sacrificed herself to get him to safety and that Theodore has erected his stronghold in the center of Union. Both Sebastian and Yukiko assault Theodore's stronghold, though Yukiko dies in the process. Sebastian is able to confront and defeat Theodore, only for Myra to arrive and kill Theodore herself while warning Sebastian to stay away from her and Lily.

Sebastian follows Myra, whose desire to protect Lily has made her insane and obsessed with keeping Lily locked in the STEM for her own "safety". Myra lashes out at him, forcing him to shoot her, triggering her transformation into a large being called 'The Matriarch', forcing Sebastian to reluctantly battle her. Sebastian defeats the monster, releasing Myra and knocking her back to her senses. He prepares to take Lily out of STEM, but Myra refuses to follow, explaining that as part of the plan to destroy Mobius, she must take Lily's place as the Core of STEM to transmit the implant-destroying signal. Meanwhile, in the real world, Kidman is ordered by the Administrator to eliminate Sebastian. She disobeys him and helps Sebastian and Lily escape the STEM while Myra enacts her plan, killing the Administrator and all Mobius operatives (except Kidman who has removed the microchip from her brain). Now free from Mobius, Sebastian, Lily, and Kidman leave the facility.

In a post-credits scene, Sebastian parts ways with Kidman and goes off to live a new life with Lily. Back at the now abandoned Mobius facility, the STEM system mysteriously reactivates itself.
