Getting Ready for Prime Time is an unmarked and repeatable quest in the Fallout 3 add-on Broken Steel.
Once you have completed the quest Who Dares Wins, you can accept the quest by talking to Scribe Rothchild. Ask Scribe Rothchild how you can further help the Brotherhood of Steel and he requests that you bring him sensor modules and old cameras to help repair Liberty Prime. These items can be found in most toolboxes and near workbenches. Once you have obtained at least one and preferably as many as your carry weight allows (for efficiency's sake), you can return to Rothchild for a reward of 100 caps and 25 XP for every camera and 75 caps and 10 XP for every sensor module you turn in. These are not awarded until after exiting dialogue with Rothchild.
- No matter how many cameras or sensor modules you turn in, Liberty Prime will never be repaired.
