The story...

 As you may have noticed we, the human kind have been so unlucky to live on such a nice planet. For thousand of years we have fought against many greedy alien species who wanted to lay their filthy green paws on our beautiful blue planet. Untold stories, movies and computer games were created to remind us on our victories and our strength. 

Year is 2077 and this time we have found ourselves  in very vulnerable situation. Centuries of wars and great battles have exhausted human kind and earth resources. And, alas just in these rainy days the greatest armada of alien ships is approaching earth! Once more as numerous times before we are in danger of extinction!!! We heave no strength to put up resistance... 

But, wait there is some slimmer hope... Earth scientists have constructed a ship and it's prototype is being rapidly built right now as you read this! The Ship is using alien technology implemented from the alien ships that crashed on earth in past. It is the only thing that can bring balance to this unfair war. 

The pilot of the ship will be selected among  millions of volunteers who would die for a chance to kick some alien ass. Maybe you are the one for the job... (find out)

Go, rage through eight alien galaxies, destroying everything that moves, learn aliens a lesson not to play games with human kind! Protect mother earth, human culture, democracy and our freedom!!!

P.S.

Be sure to scan alien galaxies for valuable resources we could use. This is an expensive war you know!
