Re: Map AI Question
You can't drive cars in Emergence(I think). You might also want to fix up your brushes so they are a bit cleaner (don't intersect when they don't have to) and apply the nodraw texture to the outside of walls that players can't see. You also don't have to name each grunt unless you want to have another entity interact with them, but you can name them if you want to. Enough of that though...
I am not great with AI, I don't know all the entites by heart, but I guess you could make a trigger to check if all the grunts are dead and then, if they are, run a script on Jessica. If you need more detailed help I might have some time later today to make you an example map.
