To promote the release of Sherlock Holmes on December 25 in the UK, Warner Bros.. have chosen to create an advergame that is played through a great Facebook application: 221B (221B Baker Street, in reference to HQ Sherlock Holmes and Dr. Watson). 221B is defined as an immersive game with 2 players (or one player who plays the two characters) that plunges the duo in the world and brings the two heroes in the first scene from the movie Sherlock Holmes. As in history, it is to investigate crimes, to discover the clues and solve puzzles. Similarly, the player's reputation as a detective is at stake
Great way to discover the film's hero, played by Robert Downey Jr and Jude Law, by embodying them. Note that a trailer has been specially designed for this advergame, enough to buzzer surrounding this film.
The brand has covered with a rich user experience and immersion of the user in his product.
