The year is 2055, more than thirty years after the events of Zero Hour, Earth suffers a catastrophic collision with meteorites. The world is thrown into turmoil as large swathes of land are annihilated. Four factions, the ADF (Asian Democratic Federation), WEA (West European Alliance), WLF (World Liberation Front), and AC (American Confederacy) are at war for control of the remaining already harder to find resources as well as the preservation of their nations and geopolitical interests. Welcome to Deep Impact.
The UAN has been playing with flame technology for years. Ever since the Chinese deployed their first dragon tanks, the UAN has had an obsession with fire. Add to this their typical strategy of taking successful designs, and instead of mass producing them, making them... big... and you get the DragonLord. Apparently, they took the chassis from one of their old overlord tanks, cut up the turret, and mounted a pair of massive, industrial strength flamethrowers too them. There is a much disputed theory, ever since images of the tank and a video of it torching protesters at the Kosovo Industrial Complex, that the Chinese are actually developing the tank to deal with a threat of zombies. The complete lack of logic regarding the theory has not stopped its circulation throughout the internet.
