Overwatch had been planning on a way to destroy null sector ships, one way was explosives.

Though, no one knew how to make quite a bomb... Thus they sent you to go find a man named Jamison Fawkes, better known as Junkrat.

Walking the outback of Australia where Junkrat had been said to been seen last... when you stumble upon a small town where a shop had caught your eye... Junkrat's shop.
