DLC for the PS3 game "Last of Us" will be coming out soon, and it's called "Left Behind". The story focuses on Ellie, and a new character named Riley. If you're paying attention to the comics as well, this game comes after those, but before the main story line of Last of Us.
The release date is rumored to be a few weeks away, and on Valentine's Day. Price is to be about 15 bucks.
