Beta 2.5 of
SecondWave is soon to be released. It features a slightly improved Iron Dragon model (boned, housecolors, actual bomb). The bombers payload differs per Chinese General. Its either a napalm bomb or a nuke bomb. Its also stealth when not attacking (or near detecting radar). Shameless ad :P
The actual POW logic was removed from the game so its not entirely possible, but Deezire did the best job replicating it so far so check out his Pro:Gen mod. But I wouldn't recomend just ripping out his code and using it unless he doesn't care.
