Law & Order: Legacies is Telltale's episodic game that was originally announced to be based on Law & Order: Los Angeles before that show's cancellation.
Law & Order: Legacies includes fan favorite characters from the entire run of the Law & Order series. The series will have seven episodes. The first half of each episode will deal with investigating the crime, and the first half will deal with prosecuting the accused. The game will have multiple endings, and it is your choice on whether the defendants are tried for manslaughter or murder. It's also possible to lose the trial, but still continue your progress in the game.
The first two episodes will be released on iPhone/iPod Touch and iPad in one universal app. The final five episodes, as well as PC and Mac versions, will be released in 2012.
