The game has a unique system involving intimidation. Whereas most superhero games require straightforward fighting, Batman Begins features the utilization of the environment to frighten opponents. Certain gadgets designed to frighten enemies during combat are provided, such as smoke grenades, flash bang grenades, and an 'HF Transponder', which summons bats to gather around and incapacitate enemies with fear. On top of this is traditional stealth gameplay reminiscent of the Splinter Cell series, such as sneaking and taking out enemies from behind. There are many ways to incapacitate enemies with stealth, using various combat and martial arts techniques.
The game follows the movie's plot very closely, with minor modifications. Throughout the game there are over 20 clips from the film that give context to the story. Though it follows the movie, the game goes deeper into each scene. For example, at the docks, the player learns specifically how Falcone was hoisted on a crane and how Batman infiltrated Arkham Asylum. It also presents a slightly alternate ending; Batman is forced to detonate the Batmobile in order to destroy the monorail tracks and stop Ra's Al Ghul from reaching Wayne Tower with the Microwave Emitter, whereas in the film, Sergeant Gordon uses the Batmobile's missiles to destroy the tracks. Two members of the film's crew make cameo appearances in the game; Wally Pfister, the film's director of photography, appears as a mob informant Batman interrogates, and Emma Thomas, producer of the film, appears as an Arkham psychologist. The only scene in the game that is not taken from the film is a second car chase with the Tumbler in which Batman attempts and fails to stop the theft of the microwave emitter that Ra's Al Ghul will use in his attack on Gotham.
