The Janus head (nicknamed Fleddy) is a priceless statue which appears prominently in Uncharted 3: Drake's Deception's co-op adventure mode. The name is a combination of Harry Flynn's and Eddy Raja's last and first names, respectively, whom Nate, along with Sully and Charlie Cutter defeated in order to obtain it.
The statue is first mentioned at the end of Chapter 1 - Borneo, after Sully remembers seeing it in the Vatican. It is mentioned to be a statue of Janus, the two-faced god. It appears to be made of stone, a block carved into the shape of two heads facing away from each other. The statue comes apart in two halves.
