Primitive War

In 1968, during the Vietnam War, the Soviet Union and its allies started experiment nuclear weapons in Vietnam. They launched their prototypes in under the ground, and the prehistoric bones and fossils are infected by the radiation of all the prototypes and causing the fossils back to life into dinosaurs. After the experiment, the Soviet Union and its allies hid their files in the other research stations because they don't want to show the public. However, the dinosaurs went on a rampage and started to attack everyone in Vietnam. The Soviet Union and its allies started to realize that their experiment went smoothly to horribly wrong.
