I should have known. The Last of Us' single player DLC was revealed and teased during tonight's PlayStation 4 All-Access event. Those who have read the rather impressive prequel comic to The Last of Us, American Dreams, will immediately recognize the DLC's premise. It's a prequel about Ellie and her friend Riley, starting with Ellie escaping a quarantine military boarding school. This is The Last of Us: Left Behind.
See, in The Last of Us we got a brief introduction to Joel's past, a past before the apocalypse, but we never got to see Ellie's past. See, Ellie grew up during the apocalypse, enough to twist any person's soul into knots. This story, however, is more than that. It makes Ellie into the person she needs to be for The Last of Us to happen. Read American Dreams, it'll fill everyone in on some of the early details.
The Last of Us: Left Behind will be released in early 2014 exclusively on the PlayStation 3. Pick up the single-player DLC alone for $14.99 or it also comes bundled in a season pass for $19.99. In the season pass, Left Behind is packaged with an already released multiplayer map pack and currently unannounced multiplayer DLC pack. Worth considering, but passing up the single-player DLC is definitely not an option.
