You complete the game and broken steel missions begin.
US Steel
Broken Steel is a DLC expansion pack, yes. If you don't have the DLC, then you don't have any of the Broken Steel content.
It's steel that Boron owns. For example: The steel that Fred has, called Fred steel.
Broken Steel was released on May 5th 2009
it does not exist! :)
O'Neal Steel
If you are referring to the US Steel Corp then, The owner you are looking for is Andrew Carnegie. He is the head of this corp.
Broken steel is already in the regular fallout3 except for Mothership Zeta, The Pitt, Point lookout, and Operation Anchorage.
Luckily, no! If you have the Broken Steel DLC, then the game will allow you to permanently wander the wastes, even if you complete every quest.
You access the Broken Steel content by completing the main game. Instead of the original ending, you will continue on to a new part of the story.
Try loading a save you had before broken steel.
