u should be able to spawn client side using the console if your in the comm vehicle, something like build_emp_aircraftfactory_(coords here) or something like that maybe?
I would say its a pretty solid way to mess with people on both teams. Tell them you can build skyjeeps for +50% lols.
LOL was that the map where I put VF's and raxes on both sides to make tank launchers? And then someone kept walling the rax and getting everyone stuck?
