Naughty Dog has unveiled the first gameplay footage for The Last of Us at the 2012 Electronic Entertainment Expo. The Last of Us is a third-person survival video game coming exclusively to PlayStation 3. The game takes place in a post-apocalyptic world, and the gameplay video showcases Joel and Ellie, the game’s protagonists, battling other survivors in a decrepit hotel. In The Last of Us the world has fallen apart due to a zombie plague. Players must travel across the United States scavenging for food, weapons, and supplies while avoiding other violent survivors and the infected. The Last of Us will be available in late 2012 or early 2013. Watch the gameplay trailer below, and check out the official Facebook page for more information.
