The Federal Emergency Mobilisation Administration is a US Government Organization and is an antagonist faction in Deus Ex: Human Revolution. Founded in 2012, it was originally mentt to protect the American people but by 2027 it has become corrupt and is now intent on detaining American political dissidents.
FEMA was founded in 2012 after the US Congress had passed the Revised Homeland Security Act of 2012 establishing the organization and quickly rose through the ranks of the US Government. FEMA was given large amounts of authority over other government organizations and agencies and was established with the original goal of keeping the United States togehter and safe thorugh invesitgations and counter-insurgency operations. It did this through both legal and illegal methods and was willing to go as far as to establish detention camps for seditious American citizens.
