Update - Naughty Dog has confirmed the release date for The Last of Us's Left Behind DLC via Twitter.
Original Story - One of 2013's most beloved games is apparently getting its next chunk of downloadable content on the day made for love. Sony has listed The Last of Us DLC Left Behind for February 14, 2014. The date lines up with a purported promotional screenshot taken by a fan.
The game listing on the Sony store gives the date, and a user on NeoGAF (via Polygon) claims to have captured an image of an ad from the PlayStation 3 storefront. The ad also teases a dynamic theme and comic to go along with the DLC, but that much is unconfirmed.
As previously reported, Left Behind will put players in control of Ellie, and shares more story on the Boston quarantine zone that ultimately leads to the main game.
