Well, there is no "radius" per se, of your team. Only camers, and such. I SAY LET THERE BE BUILDINGS THAT ARE SUPA CAMERAS.
So that noobs won't know the map at all when they start it, and so that commanders will have a pain in the ass to manage their team? Ground Control II style is fine.
aaah. Useful to know. I was thinking a fog of war where you start out knowing all the terrain, but the areas you "can't" see are greyed out. Players and manned vehicles would have a set radius of "vision". Cameras/radar would leave nice circles in the fog. Last viewed buildings stay on the map. Just a way to help keep track of stuff. I'll have to try the emp_com_fogofwar cvar to see how it works.
