It's a question we're asking ourselves right now. Despite Uncharted 3: Drake's Deception launching to critical acclaim less than a month ago, Naughty Dog has confirmed that it is the developer behind the upcoming horror title.

The debut trailer shows a young girl (Ellen Page?) and an older man struggling to survive in an infected modern America. There's an Uncharted-esque charm to the character models, but the survival horror tone is a million miles away from the cheeky escapades of Nathan Drake.

Naughty Dog's since announced that it's secretly had a second team working on The Last Of Us behind-the-scenes. The game's due out next year.

Watch the trailer after the jump. Amazing.
