From the press release:

G.E.C.K. Software Development Kit arrives next month, with three pieces of substantial downloadable content following between January and March 2009:

Bethesda Softworks, a ZeniMax Media company, today announced plans to make both its editor and downloadable content available for its award-winning game, Fallout 3 in the coming weeks. 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 Games for Windows users to create and add their own content to the game. In addition, the first official downloadable content, Operation: Anchorage, will be available exclusively for the Xbox 360 video game and entertainment system from Microsoft and Games for Windows in January, and more downloadable content coming in February and March.
“We’ve always seen the original world of Fallout 3 as a foundation for even more content. Some created by us, and a lot more created by users,” said Todd Howard, game director for Fallout 3. “It’s fun to create your own character, but it can be equally fun to create your own adventures. We can’t wait to see what the community does with the G.E.C.K.”

The release of the G.E.C.K. provides the community with tools that will allow players to expand the game any way they wish. 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.

Three downloadable content packs will be coming to Xbox 360 and Games for Windows Live starting in January that will add new quests, items, and content to Fallout 3.


Operation: Anchorage: Enter a military simulation and fight in one of the greatest battles of the Fallout universe – the liberation of Anchorage, Alaska from its Chinese Communist invaders. An action-packed battle scheduled for release in January.

The Pitt: Journey to the industrial raider town called The Pitt, located in the remains of Pittsburgh. Choose your side. Scheduled for release in February.

Broken Steel: Join the ranks of the Brotherhood of Steel and rid the Capital Wasteland of the Enclave remnants once and for all. Continues the adventure past the main quest. Scheduled for release in March.

Looks pretty neat. Very excited about the Operation: Anchorage quest, as it sounds neat.

I'm still pissed that Canada got Annexed to USA in the game.

Anyways can't wait, and atleast this comes within a few months compared to GTA: DLC which is taking years.

Very excited for Operation: Anchorage and Broken Steel, as anyone who has played the good side of the last mission can see what is in store.

Nice, very nice. I am having a blast with Fallout 3 right now. And I got my wife addicted to the game as well. She will love hearing about this.

Here's hoping for more Liberty Prime.

Awesome. I'm about 50 hours in the game right now (it's already my most played game on my 360) and it seems it will never end :)
I'm looking forward especially to the first DLC as well.

BTW: My gamerscore is 630/1000

The Pitt and Broken Steel for me, Anchorage seems to be for shooter fans.

Create your own adventures is not really something I will use the other stuff sounds interesting.

in case you thought the GECK is for the X360 version, it's not :P

and yeah, DLC sounds like a lot of shooting, well, nothing that cannot be recreated/improve with the editor I guess :P

I like shooting....
