UnrealQuakie: do you know how it's done? cause when I start a new game I have to choose others and cant do solo.
Hm. Maybe it's only possible in the sequel then. I guess you can just let the extra characters die off. For the back row that should go fairly quickly since all you have to do is have your party if you show enemies your backside.
There is supposedly some sort of save editor floating around somewhere that you should be able to use. Out of curiosity, I've just tried messing around with console commands once enabled through the .cfg file, but had no luck there, even though there should be a way to kill off your characters that way. *shrug*
