BioShock
As time passed, the gap between rich and poor increased. Frank Fontaine created charity organizations to support the underclass. His goal was to use his charity organizations to manipulate the poor. He also made a smuggling operation to supply citizens with forbidden items from the surface, such as religious material. These, along with his control of the plasmid industry, made him immensely powerful. He tried to overthrow Ryan, but the revolt was violently crushed and Fontaine was said to be dead. Ryan seized control of Fontaine's plasmid business. Within a few months, a new figure named Atlas rose as the leader of the disgruntled lower class. On New Year's Eve of 1959, Atlas and his ADAM-infused followers began a new revolt against Ryan that spread throughout Rapture. Ryan in turn began splicing his own forces, and his paranoia had reached such a level he was hanging dozens of people, mostly innocent, in Rapture's main square. In order to solve ADAM shortages, the Little Sisters were mentally conditioned to wander the city and extract ADAM from the dead, recycling it into raw ADAM in their stomachs after swallowing it. "Big Daddies", enhanced and mentally sterilized humans in armored diving suits, were created by Dr. Suchong, the scientist behind many plasmids, to protect the Little Sisters in their work.
