Part of a series of videos, this video provides an overview of WorldBuilder, the world and level editing tool in Gamebryo LightSpeed. This video is narrated by Emergent Product Manager David W. Bell.

The demo uses a sample application, "Mangled Metal", to demonstrate real-time editing and rapid iteration on a running instance of a game. The sample appication is running in a PC window on the same machine as the tools, but could just as easily be running on a networked PC, Xbox 360, PS3, or Wii.
