Vulcan is the ultimate weapon of mass-destruction. Built by all T2 land/air cons it is basically a spinning wheel of Big Bertha plasma cannons that can shoot across the map and tear down whole bases. It takes giant resources to build but when it is in place it basically wins you a game. 

However, remember that it also consumes great amounts of energy to shoot (14500 energy/shot), hence don’t build it if your income is below 35k energy.
