Mass Effect: Genesis is a downloadable "interactive introductory comic." Genesis serves as Mass Effect's entry point for new players, familiarizing them with the story of the original game and letting them make six key plot decisions that mirror those available in the main game. Once downloaded, the comic plays between the opening level and character creation. Two versions of the comic are available, one featuring a male Commander Shepard and the other a female Commander Shepard.
