Broken Steel

Broken Steel will be the third Fallout 3 downloadable content pack, to be released in March 2009 for Xbox 360 and Games for Windows Live.

In this DLC pack, you will 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.

As of yet, there is no news of a PS3 release.

Spoilers and Character Generation Controversy
Given only one possible Fallout 3 ending permits the player character to survive, it seems likely that a new or heavily modified character will be required to play, unless the assumption is made that the player chose the "cowardly" path and escaped (which one might assume would not put him or her on good terms with the Brotherhood of Steel). The radiation levels appear to be so high in Take it Back! that it seems unlikely the character could even proceed as a ghoul In the final movie, it appears that you are reduced to a goo pile. However, when contrasted against the "cowardly" ending, Sentinel Lyons is not likewise reduced, and the goo pile present in the final video may simply be the result of the quickest way to code an ending without having to take into account the various physical appearance variations (largely referring to the 8 different ethnicity/gender combinations).

Additional Possibilities which would permit continued gameplay include:
 * 1) Followers that are immune to radiation will no longer refuse (because now the story goes further), and no-one will perish.
 * 2) The player will not automatically die (since up until the script trigger, the radiation is manageable, in comparison to the impossibly high Vault 87 radiation levels)
 * 3) The player is saved and awakens inside the Citadel under the Brotherhood's medical care
 * 4) The player is turned into a ghoul
 * 5) The player's mind is kept intact and is transferred into a new android body similar to that from The Replicated Man Quest
 * 6) The player is treated with the same Enclave treatment that saved Colonel Autumn earlier in the game.
 * 7) Sarah Lyon's death becomes canon OR the player is required to take the 'cowardly' ending to continue (much like the dialogue choice to give Autumn the purifier password or refuse; one option results in 'game over').
 * 8) Some aspect of the Purifier fails to work as well as anticipated (due to damage) and the radiation levels and purifier impact are lower than Dr. Li expects.
 * 9) President Eden did something to protect, copy, or fool the player during their meeting.
 * 10) You get cloned, in some other creative way.
 * 11) Its all been a horrible, horrible dream since Tranquility Lane.
 * 12) The player somehow grow immune to radiation.
