Prototype is a casual stealth game who tells a story about June Thatcher, a chemist who has been fired from her job as a researcher at Union Medical. Union Medical fired June because she’s been caught red-handed from trying to steal her CEO's skin sample which makes the CEO angry. Since June cannot retrieve her belonging at the company, she’s sneaking at the night of June 24th 2013 to take her secret project from her office while also taking as much sample as possible for her research.
