In future America, the downloaded people in the Ten Sigma Program fight endless battles. The struggles span all possibilities: face-offs with knives and clubs, skirmishes as Roman legionaries, pitched WW1 trench warfare, duels with ultra-modern hypersonic weapons, and everything in between. The combatants who live are rewarded with another battle until they reach the unreachable score of ten sigmas. Those who die are expunged from the system, gone forever. The methods, so harsh they go beyond anything possible in the real world, are necessary for the end goal: violent evolution to produce the greatest warriors in all of human history
