Earth, 2019: A colossal asteroid crashes down to Earth.The North Korean Government quickly seals off the island chain, claiming the mysteries of the asteroid for themselves.

The United States responds by dispatching an elite team of Delta Force Operators to recon the situation and report back to the Pentagon. Amid rising tensions between the US and North Koreans, the asteroid suddenly bursts open, revealing a massive, 2km high alien ship. The ship generates an immense force sphere, freezing a vast portion of the island and drastically altering the global weather system. Earth is being invaded as we speak.
