Invasion: California

The invasion of California has begun, threatening to trigger World War III.
Greater China and its South American allies control Mexico, and their armies are poised on the Rio Grande, ready for the next phase of the North American conquest.
It is 2039. The Chinese are launching their secret weapon against the American border fortifications. At the same time, an amphibious fleet steams toward San Francisco. The Chinese have formed the Pan Asian Alliance and signed a war-pact with the South American Federation. Glacial cooling has brought the Earth to the brink of starvation. Now, U.S. soil is the most valuable commodity in the world, and the aggressor powers plan to divide it amongst themselves.
America is down but she is not out. The military has some deadly surprises for the invaders, but it may not be enough. Enemy wave assaults, vast armor battles and new drone fighters turn the war into a seething cauldron of mass destruction.
