Harden Artillery is a UEF research that allows Fortified Artillery to use the Hardened Mode ability, for 500 energy. The ability allows Fortified Artillery to transform, for 30 seconds, into what is essentially a vastly more powerful Point Defense. This ability briefly sacrifices some range to grant the Fortified Artillery direct fire, faster fire rate, larger splash radius and greater damage.
