内容简介：
In the mountains of northern New York lies the urban metropolis of Pandora City. Its eight million plus citizens enjoy a low crime rate and the support of the massive Hyperion Medical Corporation International, formally one of the biggest medical companies in the world. Unfortunately Hyperion is on the brink of bankruptcy. On October 23, a group of cargo planes crossed the border and reached Pandora. A huge paratroop drop commenced. All the civilians in the city were killed. The next day a team of U.S. Army Rangers went into the city as an expeditionary force. They were killed, and their helicopter returned covered in an unknown airborne virus. Now, a small team from the biohazard response unit Rainbow Group, along with a couple hundred Marines, has come to the city to rescue survivors. But they will soon learn that there are bigger powers at work in the dead streets of Pandora.
