The G.E.C.K. interface

The official editor for Fallout 3 and Fallout: New Vegas, called G.E.C.K. (Garden of Eden Creation Kit, named after the terraforming device of the same name from the series), that can be downloaded for free, allows PC users to create and add their own content to the game. The editor requires a pre-existing installation of the associated game to function, as it requires the usage of several resources within the game.


The G.E.C.K. provides the community with tools that allow players to expand the game. Users can create and edit any data for use with Fallout 3 or Fallout: New Vegas, from building landscapes, towns, and locations to writing dialogue, creating characters, weapons, creatures, and complex scripting.

The G.E.C.K. has an interface similar to that of The Elder Scrolls Construction Set, which is useful to those who are familiar with it; however, the functionality of the G.E.C.K. is far expanded over that of the Construction Set, much like the functionality of the game engine. Scripting options for the G.E.C.K. can be expanded using the Fallout 3 Script Extender or New Vegas Script Extender (or FOSE and NVSE, respectively) much like OBSE for TES IV: Oblivion and SKSE for TES V: Skyrim; however, these script extenders are not compatible with versions purchased via Direct2Drive, and having Games For Windows Live active will cause the game to crash as soon as you try to access Games For Windows Live.[1][2]
