hard to say what my last weapon used use. In Supreme Commander Forged Alliance final attack with a combination of multiple czars, Galactic Colossus, Support Armored Command Units, T3 bomber, T2 gunships, Aeon Experimental Battleships, cruisers, destoyers, and a nuke. I would eventually build a base, with walls, if zombies tried to get close I think I have enough fire power.
