Batman: The Enemy Within

Like most Telltale games, the game features a similar episodic format found in other titles (such as Game of Thrones, The Walking Dead, The Wolf Among Us and Tales from the Borderlands). The player controls Bruce Wayne and his alter-ego Batman, with the game evenly split for both characters. The game features a branching narrative, similar to past Telltale games, giving the player options in approaching a situation and having that choice affect later events in the game. If the player had played the previous game, choices made, such as saving certain characters or stopping a criminal, may also be imported, though the game can be played as a standalone title.

The game includes action sequences that are resolved similar to Telltale's other games, using quick time events. The series also includes investigation sequences, allowing the player to use Batman's detective skills to investigate areas. Sections of the game also present situations to the player where they may choose to approach as Bruce Wayne or as Batman. Crowd Play, a feature implemented in the predecessor, also returns for The Enemy Within, allowing streamers to let their audience interact with their session with the game.

The player once again assumes control of Bruce Wayne / Batman (Troy Baker), a billionaire who secretly fights crime in Gotham City. His butler and former legal guardian Alfred Pennyworth (Enn Reitel), Police Commissioner James Gordon (Murphy Guyer), and Wayne Enterprises Chief of Technology Lucius Fox (Dave Fennoy) return to assist Batman in the field. The game introduces "The Agency", a mysterious government organization with its own agenda led by the ruthless Amanda Waller (Debra Wilson). New supporting characters are introduced, including Special Agent Iman Avesta (Emily O'Brien), one of the Agency's operatives and a fan of Batman, and Tiffany Fox (Valarie Rae Miller), the daughter of Lucius and an employee at Wayne Enterprises.

"John Doe" (Anthony Ingruber) and Selina Kyle / Catwoman (Laura Bailey) also return, now members of a group of criminals called "the Pact". Other members of the group include Riddler (Robin Atkin Downes), Bane (JB Blanc), Dr. Victor Fries / Mr. Freeze (Matthew Mercer) and Harleen Quinzel / Harley Quinn (Laura Post).

Batman: The Enemy Within received generally positive reviews and is considered to be an improvement over its predecessor, earning praise for its story, choices, action sequences, and the portrayal of the Batman mythos. The game won the award for "Performance in a Drama, Supporting" with Debra Wilson at the 17th Annual National Academy of Video Game Trade Reviewers Awards, whereas its other nomination was for "Game, Franchise Adventure". Episode 5 was nominated for "Outstanding Achievement in Videogame Writing" at the Writers Guild of America Awards 2018, while the game itself was again nominated at the 18th Annual National Academy of Video Game Trade Reviewers Awards, this time for "Writing in a Drama".

The game's portrayal of the Joker stood out for many reviewers, with the opportunity to prevent him from becoming a villain critically lauded. Scott Maslow from GQ said it managed to make "Batman's most overexposed villain interesting again; The Joker has always said his past is multiple-choice, but this is the first time I've felt like I was the one checking the boxes". Bradley Shankar from MobileSyrup gave a positive review, saying that "Batman: The Enemy Within offers one of the greatest Joker stories ever told". He explained that "while there have been numerous great interpretations of the Batman-Joker relationship over the years, there has never been one quite as complex and morally grey as what Telltale has created with The Enemy Within".
