I just caught a glimpse of a shadow spy in a room.

I have caught a couple at the vault door. How do I catch these guys when they are in my vault?

Poke them in the eye

If you spot the Mysterious Stranger, click on him.

There's a subtle piano play when he spawns in a random room, and a another one when he dissapears, the caps he drops is random sometimes a few hundred sometimes a few thausend.

When you click on him, he gives you a bribe, anywhere from a few caps. to many thousands of caps.

If your view is zoomed out to max, the sound will NOT be audible. When you are zoomed in, you can navigate with the sounds help ; it gets louder as you movve the camera closer, lower when you moved it away from his general area.

he can spawn deep inside rooms, even inside closed areas deep in rooms. eg: http://steamcommunity.com/sharedfiles/filedetails/?id=901101102

important note: if any part of your base does NOT have power, then even if you ehard the sound for the Mysterious Stranger, you will Not find him.

good luck have fun

PS: it is MUCH easier to find him in rooms that have NOT been updraded. :)
