The website for the up-coming Young Justice: Legacy console/computer game has been updated with short biographies and turn-around renders of the playable characters (a couple of which are shown above).
Additionally, Young Justice: Legacy writer Sharon Scott has blogged about the process of working with WB and Greg Weisman on the concept for the game’s plot:
Not only was WB prepared to let us explore the 5-year gap [between Season 1 and Season 2], but they wanted a storyline that would be part of the YJ canon similar to the Young Justice comic books. With all the industry talk about transmedia storytelling, I expect we will be seeing more projects like this, but this was the first time I’ve had the opportunity to get involved at this level. But since the entire game revolved around the story, the development team couldn’t begin the real work on the game until we had concept approval. Heroes, villains, locations, and the like would all be dependent on where we ultimately went with the story.
The game will be released next-year.
