I've started work on a sith infiltrator duel map, you can go inside and outside and everything, so far it looks really sweet. If you want to see a sweet pic even though it's not textured yet, I can post one.

I've run into a problem though, I'm not sure I should put any player start's or weapons or anything. I seen all the .shaders in the assets0 file and the shaderlist seems to be easy enough to make a new one. Would that work or do i absolutely need a .def file?

They are not completely compatible, but most of it is.
