Just when you thought the alien invasion was successfully fought off once and for all, new waves of alien scum come in numbers far greater then 5 years ago. The government is alarmed.

Just when you thought the alien invasion was successfully fought off once and for all, new waves of alien scum come in numbers far greater then 5 years ago. The government is alarmed.

An abstract from an official intelligence report:

Our satellites have located as many as fifty alien interceptors rapidly approaching planet Earth. Detailed analysis of the digital image data revealed a larger object as well. Without a doubt, it's the Big Brain, thought to be killed 5 years ago. Looks like we should start a search for a new hero right now!

Who is going to win this time? Will the humanity be able to form a force capable of stopping the attackers? Or will all humans be enslaved by an alien civilization that came from a far away galaxy?
