The first batch of Fallout 3 DLC has gone live. Operation: Anchorage will set you back 800 Points and it's available everywhere except Japan.
Here's a slice of official info: "Enter the simulation pod and embark on one of the greatest military campaigns of the Fallout universe - the liberation of Anchorage, Alaska from its Chinese Communist invaders.
"Experience harrowing winter combat using Fallout 3's patented V.A.T.S. targeting system, and employ powerful new equipment like the Gauss Rifle, Chinese Stealth Armor, Winterized T-51b Power Armor, and more."
The Major notes that you should keep an eye on your Pip-Boy 3000 for the 'Outcast Distress Signal' on your radio which will lead you to the new content.
Operation: Anchorage is also available on PC but not PS3.
