Shoelip: Oh wow, thanks.
I wonder if anyone has made any single player modules with it.
There were a couple a long time ago. If I remember right, a pair of modules I played were called "The Quick and the Dead" and "New California". They were decent, all things considered. Sort of a dark fantasy, post apocalyptic world.
There was also a multiplayer zombie survival horror module that I played a bit, but, I've forgotten the name of it.
