Anyone else having difficulty here? I already finished the game, and have only seen one the whole time. I actually shot him, but that's NOT what you need to do. I've ran around every where, and with no luck finding another one. Ideas, thoughts, suggestions would be welcome, thanks.
Desire sensor at its finest, you've probably encountered 10 of them but not been paying attention to the map in normal circumstances. Basically you just need to force NPC spawns as fast as you can for the random chance one will appear. Notoriety 3 is good for this as NPCs run away forcing new ones to spawn a lot. Or you can just run around with an eagle eye on the map waiting for one to spawn.
As far as I know there is no known technique to force a spawn. I had one appear while throwing money all over town and another spawn while standing stationary cos I was typing on here. Just keep looking (I know it sucks)
Although the law of public complaints, now you've made this topic one will appear before you get a chance to reply =D
I finally did it! This works, I think, it takes time, but I was able to get 2 to spawn in a time period of say 30 minutes (yeah, sucks, but running around for 2 hours yesterday doing it otherwise, didn't get me any).
Urgh,finally a courrier,I thought I was prepared,I was on a horse,chased him easily and jumped him barehanded,he was still very much alive,but did not count towards catch a courrier. So NO HORSERIDING!
