Alien INVASION???

On August 10, 2013 the first ever reported of a colossal being that began a six day rampage across Eastern United State ended when the American decided to use nuclear warheads to take down the beast. Does this event heralds some kind of nuclear/biological disaster that spawn this colossal being or according to some theorists, an invasion of another species that have laid dormant all this while. We do not know. 

The damage, however caused by the being later dubbed as "Kaiju" and named as the "Trespasser" by the world, had made three American cities uninhabitable due to the nuclear fallout caused by bringing down the "Kaiju". Tens of thousands lives were lost due to "Trespasser" rampage and billions of damages recorded. San Francisco, Sacramento and Oakland were then renamed as the Exclusion Zone. The American mourned for their losses and moved on. And Humanity thought that it was the first and last of this kind of unprecedented events.

However, 7 months later, 5th February 2014, another Kaiju later named "Hundun" made "landfall", a term coined for the Kaiju attacks, near Manila, Philippines causing widespread death and destruction around the city itself. "Hundun" were finally brought down by a tactical nuclear strike. The excrements from the Kaiju "Hundun" totally wreck the ecosystem in and around Manila city thus making Manila into another San Francisco.

From then on, people living in coastal nations or cities were in fear of another Kaiju attacks. 3 days later, a Kaiju warning system was established to let people know when and where another Kaiju will be making landfall and thus allowed to prepare before the Kaiju arrives. This system was later named the Kaiju Emergency Alert System.
