Naughty Dog and Dark Horse Comics have teamed up to create a four issue comic book series that will delve into Ellie's past. The Playstation Blog posted the first images from the comic, and offered this description:
The Last of Us: American Dreams is a four issue comic book series that peels back the layers on the early days of Ellie as it dives into her backstory. It will expose her personality and the motivations that drive her as it explores the first steps of the journey that leads to becoming the character we ultimately meet in the game.
Sony wasn't able to offer an exact release date for the comic, but said that it will release in conjunction with the game next year.
