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.

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 (i.e., you appear to be liquefied).

Another, less plausible solution is that the character is cured using the same miraculous treatment as Col. Augustus Autumn received following his attack by James, but that would seem to conflict with the end game movie.
