Operation: Anchorage will sell for 800 Microsoft Points ($10) on PC and Xbox 360. Per an exclusivity agreement with Microsoft, the content will not be released on PS3.

The second pack, The Pitt, arrives in February, and offers a look at post-apocalyptic Pittsburgh. Broken Steel, due in March, continues where the main adventure left off, allowing players to join the Brotherhood of Steel, and raises the game's level cap to 30.
