The goal of "The Player" is to engineer a lethal bio-weapon by which to wipe out the entire human race, spending points on evolving your disease so that it can spread to as many countries as possible before the world governments begin to fight back. The bio-weapon can be a virus, a bacteria or a parasite and can have all manner of horrific side-effects - the game encourages "The Player" to develop their disease slowly so as to avoid detection as well as ensure it spreads rapidly.
