During stealth segments, the player can interact with the environment to create various circumstances that scare off enemies, such as explosions or dropping crates near them, making them easier to subdue.
Inside a run-down building full of explosives in Gotham City, Batman confronts a group of thugs working for Dr. Jonathan Crane.
The game then flashes back to a year ago in the Himalayas, during Bruce Wayne's training with Henri Ducard and the League of Shadows, led by Ra's al Ghul.
A week prior to the game's opening sequence, learning that mob boss Carmine Falcone is involved with a drug shipment at the Gotham Docks, Batman captures him and leaves him for the GCPD to find.
He then informs Rachel of the shipment, and provides her with enough evidence to enlist Sergeant James "Jim" Gordon, one of Gotham's few honest cops, to arrest Falcone.
Batman catches Flass and threatens him into revealing that besides drugs, Falcone's men are shipping some chemicals to Crane, who works at Arkham Asylum.
Lucius develops an antidote and cures Bruce of the gas sprayed on him, which he learns is a dose of toxin made by Crane which induces horrifying hallucinations and irrational fear.
After sneaking out of the asylum and avoiding the pursuing police, Batman takes Rachel to the Batcave, where he manages to save her life, but keeps his identity secret from her for her safety.
Later, during his birthday party at Wayne Manor, Bruce is confronted by survivors of the League of Shadows, led by Ducard, who reveals himself as the true Ra's Al Ghul, and informs him of his plan to destroy Gotham by vaporizing its water supply using the stolen microwave emitter, which will render Crane's toxin airborne and cause mass hysteria.
Batman shifts focus towards stopping the League, after Ra's loads the microwave emitter onto Gotham's monorail train to transport it to the city's central water hub.
Batman Begins producer Emma Thomas and cinematographer Wally Pfister make cameo appearances in the game as an Arkham Asylum doctor and a Falcone mobster, respectively.

Oldman, who reprised his role as Lt. Jim Gordon, did not name a developer in the interview but anonymous sources reported that The Dark Knight was a secret project of Pandemic Studios and EA.
