Fallout 3 random encounters

Throughout your adventures in the world of Fallout 3, you'll encounter random happenings in the Wastelands. There are certain places where random encounters can happen, but once you "activate" a random encounter in a particular area the spawn won't change, even if you come back days later.

What you can do is save outside the area before the event spawns, and that way if you don't get the spawn you're looking for you can revert. What is so significant about these random events? For one, rare weapons such as the Firelance has a chance of appearing.

Random encounter locations
These are the known locations so far:


 * Just outside of the entrance to Rockopolis. Fast-travel to Smith Casey's Garage and go in and come back out.  From the entrance, turn West and a teeny-bit North you'll be there in about 30-40 seconds.


 * Fast-travel to Jury Street Metro Station and head Southwest down the road towards the radio tower. From there travel Southwest and you'll run into a small canyon.  In the canyon is where the event spawns
