The game follows soldier Nathan Frost, who is enhanced with nanotechnology following injuries on a mission and sent against a military regime known as the Republic. Players control Frost through a series of linear levels, using enhancements both in combat and to manipulate security devices hazards such as cameras. The game was originally planned as part of the Deus Ex series. The game eventually evolved into its own product, but retained gameplay elements from its Deus Ex roots. (wikipedia.org)
