I've noticed that quite a few people have mentioned on here the use of maps when GM'ing a game.
The mission that is in the book (and I think the ones in the GM kit) come with maps made up, but I'm looking to start my missions with the free ones that are available from this website.
So, I was wondering if anyone had either come up with maps for these missions which I could use, or knew of any free software I could use to create maps myself?
