The Operation: Anchorage DLC will see Fallout survivors participating in the historical liberation of Anchorage from the Chinese Red Army by way of a virtual reality simulator.

"Operation: Anchorage focuses mainly on a combat/stealth path," said Bethesda DLC producer Jeff Gardiner to IGN. Gardiner noted that the pack will include new weapons, armor, achievements, and a "Covert Ops" perk. "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," he added. "These include interactive Strike Teams under the player's command and unique armor, weapons, and other exotic gadgets."

Gardiner also revealed a few details of the second and third packs, planned for February and March releases, respectively.

The second pack, titled The Pitt, will be set in Pittsburg, which apparently escaped nuclear annihilation.

"While Pittsburgh wasn't directly hit in the nuclear onslaught, it's still had years of decay. The surrounding water is also heavily irradiated, which tends to have an effect on those that live near it," said Gardiner.

Gardiner also revealed that the third DLC pack, Broken Steel, will increase the game's overall level cap. Broken Steel will also add new monsters and perks, and is set to allow players to continue exploring the wasteland after its completion.
