Bethesda’s Fallout 3 mod creator, nicknamed the Garden of Eden Creation Kit, went online this week.

The new Web site has the mod tools available and a library of how-to articles. Fallout 3 Nexus is a good community source for new content.

Bethesda has a history of good mod support for Morrowind and Oblivion as well as downloadable content, and Fallout 3 is getting the same treatment.

Three downloadable packages have been announced — “Operation: Anchorage,” which simulates a battle between the US and China, will come out next month, followed by “The Pitt” and the new city of Pittsburgh in February and “Broken Steel,” a continuation of the main quest, in March.

IGN has an in-depth interview with Producer Jeff Gardiner about January’s “Operation: Anchorage.”

“The Chinese red army is everywhere, and the player will first have to secure the surrounding mountain side and then fight their way into the Chinese base,” summarized Gardiner.

“The player will have to use a lot of their standard combat skills, along with several new tools that will only be available in the downloadable content. These include interactive Strike Teams under the player’s command and unique armor, weapons, and other exotic gadgets.”

The packs are exclusive to the Xbox 360 and PC, and they will cost $10 a piece. 

Despite the price tag, I think Bethesda’s new DLC is exactly what it should be: four to five hours of content that supplements the main quest and expands on the story and gameplay of the core game. They are substantial, experimental mini-expansions rather than superfluous aesthetics like Oblivion’s infamous horse armor.

As Gardiner said in the interview, “It’s important to our team to use DLC as a way for us to flex our creativity, to try new things and answer the ‘wouldn’t have been cool if we did this?’ question that always comes up towards a games completion — when it’s too late to try them!”
