Not much actual game play is shown during this panel, but more the process of creating the motion capture that goes into the game. The panel stars three key members of the development team, but mostly the credit goes to Nolan North, Emily Rose, and Richard Mcgonagle.
We get to see the three actors complete a scene from Uncharted 3. As well as some of the more comedic moments from their session. Thanks to gamespot for all the lovely videos, enjoy!
