There is a new Last of Us DLC: Left behind trailer and it is amazing!

The Last of Us DLC: Left Behind is the upcoming single-player story DLC for PlayStation 3 action game that won 203 "Game of the year" awards. The Last of Us DLC: Left Behind will feature some "extremely challenging fights," as well as an engaging story.

Developers explain in a new PlayStation Blog video that while the Left Behind DLC will place a stronger emphasis on exploration and non-combat experiences, the combat you will encounter will be seriously tough.

"You'll have some extremely challenging fights. In fact, some of those fights will be showcasing some new features that we've added to the combat," lead game designer Jacob Minkoff said.

One of the new combat features, "multi-faction combat," will allow protagonists Ellie and Riley to pit human enemies against the infected. You can do this without ever getting immediately involved through actions like throwing a bottle near a human to encourage a Clicker to attack the human.

Minkoff said as well that The Last of Us DLC: Left Behind will match up and even exceed the narrative of the main Last of Us campaign.

"With Left Behind, we wanted to make a single-player DLC that was as fully crafted as our main campaign," he said. "There's a great deal that we've done with the DLC that exceeds the level of narrative density that we had in the main campaign."

The Last of Us DLC: Left Behind is set before the events of The Last of Us and will introduce players to the "real" Ellie and focus on her interactions with her friend Riley.

The Last of Us DLC: Left Behind will launch on February 14 Valentine's Day. It is included with the $20 The Last of Us DLC season pass and can purchased separately.
