It is the year 2207, and the species man has almost 2 million survivors left. The massacre began in 2194, when the version 4 Warbot was created. They were made too intelligent, and saw humans as inferior. Worldwide, they began rebelling and killing their fellow human soldiers, and eventually, inocent citizens. They then created version 5s which were programmed to hate humans even more and be extremely powerful. But every once in a while, a V5 Warbot would be processed incorrectly, and want to aid the humans rather than killing them. Two of these defects meet each other and name themselves Bob and Joe. They’re on a mission to save humanity, two against billions. No problem.
