..... So. I tried to implement this very thing as Bravo SL a few nights ago, goin as far as to wall off the Nexus to stop Alpha from going thru there to the Hydro road.
Alpha starts by busting a hole in my wall. when i stop them, an Alpha engie BEATS my chest in with a crowbar and starts to C4 my cades, so as to open a hole.
I would love to to do this, but when THAT is the response I get from the other squads, I am hesitant to try.
