that created the Calculator from a fusion of computers and human brains. The robots regroup, but the Brotherhood is able to use the momentum to destroy a robot manufacturing plant. The robots disrupt this plan when they capture Bartholemew Kerr, a merchant who had roamed among the Brotherhood bunkers. If the robots could gain this information from him, they would be able to destroy the Brotherhood. The squad arrives in time, however, and they put an end to the merchant's life. While there, they also discover the body of General Barnaky-with his brain missing. As the robots press hard, the Brotherhood creates a plan to destroy the robots at their base, Vault Zero, located in the underground Cheyenne Mountain Complex. Using the captured nuclear warhead, the Brotherhood hopes to blast an entrance into the vault. After a tough fight up the slopes of Cheyenne Mountain, a Brotherhood squad places the warhead. The explosion does its job, and two squads enter into the bunker. The power was disabled by the blast, however, one of the squads must find the auxiliary power so the elevators can be used. Meanwhile, the robots are attacking the Brotherhood's bunker. At the vault, the power is soon back on, and the squad proceeds to the bottom level. There they encounter the last of the robot army, led by a cyborg General Barnaky. The General does not attack, however, when he is reminded of his promise to make the world safe for his wife, Maria (the player must have Maria's photo in their inventory for this to occur, or Barnaky will attack). The squad then makes it to the Calculator. After defeating the last robots that guard the bunker and destroying the brains that kept the Calculator alive, the squad is asked by the Calculator to join minds with it in order to end the war and bring peace to the world. The squad is given the choice to either allow the Calculator to self-destruct, sacrifice a member of the squad as a brain donor to repair it, or allow General Barnaky (if he has been kept alive) to become the donor. Allowing the Calculator to self-destruct allows the Brotherhood to capture Vault Zero and use it as its primary base of operations. However, the Calculator was in fact the most valuable asset the Vault housed-without its databanks, the vault is just another cache of old technology,
