For those of us who don't know what the Fallout 3 Numbers Station is, it's a strange easter egg located in the Fallout 3 files. [url=http://message.snopes.com/showthread.php?t=62673]Read this if you want to find out more[/url] Anyway, the only known variables to activate it were: 1. Killing Three Dog 2. Not completing the Galaxy News Radio Quest 3. Destroying Raven Rock However, after a few years, I have figured out the final variables. The final seven variables (in any order) are: 1. Blow up Megaton 2. Kill Fawkes immediately after Raven Rock. This is going to be quite difficult, so bring some very powerful weaponary. 3. You need the Lincoln Repeater. (You don't need to kill any of the people on this list with it) 4. Kill the Chinese Remnants in Mama Dolce's 5. Get through Fort Constantine, and attempt to launch the ICBM. (The actual weapon won't launch, so don't be alarmed if you don't notice any changes to the game world) 6. Kill Harold in the Oasis Quest (fire or destroying his heart works) 7. Kill Alistair Tenpenny. If you complete the Tenpenny Tower Quest, make sure to side with Tenpenny, otherwise the Ghouls will murder the humans after a few days. After that, I found the GNR Numbers Station Radio Signal. Anyway, if you ever want to find the Numbers Station for yourself, these are the steps you have to follow. Enjoy.
