Heart Breaker (itch) (Joe White)

The year is 2050 and the planet is on the brink of a resource war.  The Great Kingdom Nation (GKN) is out-gunned, and out-matched, and requires intelligence and information for it to stand a chance. 

It does have one thing the other nation states don't have though... The Atomic Size Manipulator Ray (ASMR for short).  This allows a person to be shrunk down to a Cellular level, meaning they can be placed inside, another human being. From there, the shrunken person can help or hinder the persons body, depending on the intent.

Your mission, should you choose to accept it, is to be injected inside the heart chamber of an enemy super soldier. There you will help with "extracting information," whilst the subject is "encouraged" from the outside. Careful though! The soldier immune system has mutated too, and is much more responsive than before. Truth be told.. we have know idea to what extent..
