Somewhere in the far future, mankind succeeded in building the first artificial beings from biological and electronic components.
Not surprisingly, one of their first applications were as highly intelligent battle drones. These drones are called Bionics. The Bionics constantly enhance their artificial brains by learning rapidly from all previous perceptions. Their self-awareness develops day by day. Eventually, they chose to turn against their creators.
All training rooms in the laboratory are now occupied by aggressive battle machines. Their utmost desire is to survive in all scenarios and to preserve autonomy.
