Crackdown 2 takes place 10 years after the events of Crackdown. After "saving" Pacific City, there was a short time of peace. Then, according to the Agency, a new medical student named Catalina Thorne was accepted into the Agency as a scientist. However she was found to have been performing her own unauthorized experiments and was kicked out. Afterwards, her life was ruined, with her blaming the Agency. Later, she broke into the Agency cloning facility which housed the original agents, and introduced a virus into them which mutated the already genetically modified Agents, who became mindless and enraged, going on a killing spree before dying hours later. She then went on to destroy the research labs, sending the project back to square one and single-handedly destroying the Agent program.
