The official editor for Fallout 3, called the G.E.C.K. (Garden of Eden Creation Kit), will be available for free download in December and will allow PC users to create and add their own content to the game.

The release of the G.E.C.K. provides the community with tools that will allow players to expand the game. Users can create, modify, and edit any data for use with Fallout 3, from building landscapes, towns, and locations to writing dialogue, creating characters, weapons, creatures, and more.

The G.E.C.K. will likely have a interface similar to The Elder Scrolls Construction Kit.
