has anyone here completed shadows of amn, or it's expansion, in single player mode without npc's?

You are kidding, right? :D

On the off hand that you aren't, do a search for "solo"...

Many, many, many people have done this.

But not me :)

Use the search engine as Earl Grey suggests and look for 'solo'. There have been many questions and stories about such things.

oh sorry then i looked first but i dident try typeing "solo":)
