During tonight's PlayStation All Access
event on Spike, Naughty Dog co-founder Evan Wells revealed a brief teaser trailer for "Left Behind," the upcoming prequel DLC episode for The Last of Us
. The DLC will focus on Ellie's life before Joel, when she was palling around with her friend RIley, played by actress Yaani King
The PlayStation Blog
confirms Left Behind is a single-player DLC campaign - Naughty Dog's first single-player DLC, amazingly - and that it's due in "early 2014." Left Behind is included in the game's season pass, but Naughty Dogs says, "If you're only interested in the single-player DLC, you can pre-order it starting November 19 on the PlayStation Store for $14.99."
