Yeh, before the game was out, everysingle MKD charcter was tested in Puzzle. Or some did. Because all they have to do is crush the character down. Theres a picture of a staff member in the Krypt where in the back-ground where you can see Puzzle Bo'Rai Cho fighting in the Chambre of Artifacts. The reason they didn't put it in was the Special Moves, or Game Space.
