Deus Ex: Human Revolution
In Deus Ex: Human Revolution, Adam Jensen visits a supposedly abandoned warehouse to find the hacker that infiltrated Sarif network. Upon descending into the lower levels, he will find out that the warehouse is owned by FEMA, and is guarded by both armed humans with augmentations and at least three 80-X Boxguards.

Deus Ex
FEMA is tasked with handling responses to natural and domestic disasters within the United States. After a blackmail performed by Bob Page, Walton Simons took over as the director of FEMA in order to further MJ12's goals of a New World Order. This let FEMA gain significant power, taking control of smaller organizations such as UNATCO, and allowed them to control the media and transportation. They are capable of imposing curfews on more populated cities, and have their own private armed forces to help enforce their laws.

Throughout Deus Ex, FEMA takes an unusually aggressive stance against terrorism and rioting in cities such as New York to improve their public image and excuse their extreme actions. By the end of the game, they either kill or force certain individuals within UNATCO to resign if they are too experienced, or otherwise not naive enough to follow MJ12's orders entirely faithfully. Many of MJ12's Troopers, Commandos, Men in Black and Women in Black work for FEMA as a public front for MJ12's normally covert actions. During the events of Deus Ex, Walton Simons may die, depending on the players actions. After JC Denton's failed merge with Helios, the World economy Collapses and FEMA probably disentigrates. It is never referred to in Deus Ex: Invisible War.
