75%

This is a Hack'n'Slash-type third person game. The goal is to kill as many civilians/soldiers as possible and survive their assaults.

 The player embodies a robot whose goal is to solve the problems facing the world population, that is to say the famine. Following his calculations, he finds that the most radical solution is to decimate 75% of the populations of the city where he was conceived, San Francisco.  It will have military forces against which it will fight with firearms.
