Hello, xx142-b2.exe
  
  This is the year 2413,
  humanity is enslaved by an alien race for more than two centuries already.
  
  You are an AI weaponized virus built to infiltrate the alien network and deactivate all power generators and weapon systems.
  
  The alien antivirus will detect and delete you after 13 seconds.
  
  But remember: a file is never really deleted. Use the execution backtrace from your previous attempts to break in and destroy the main memory core.

  You freed humanity from slavery.
  
  
  
  How about a nice game of chess?
