What Is It?

FGD is the file extension for Hammer's game definition files. They define all of the entities of a game so mappers can select them from within the editor.

History

FGD stands for Forge Game Data. While Hammer was originally called Worldcraft, it was developed under the name The Forge. Due to trademark issues, that name couldn't be used for the final version.
