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.
