Half-Life 2: Desperation is a single player modification of Half-Life 2 Episode 2. It takes place in the Midwest United States during and after the 7 Hour War. This however leads to a last ditch nuclear strike on all Combine overrun areas (yours being one of the these) by the United States Military. Though it fails to stop the invasion, it severely hinders the occupation of Combine forces (as well as the survival of pretty much anything) in the irradiated wasteland that is the American Midwest. You fill the shoes of an average citizen of a small town that is within the blast radius of the nuclear strike and take refuge from both the threat of aliens and the military's payload in a makeshift bomb shelter. A majority of the time after the blast you will operate out of this shelter and gather needed supplies as well as eventually take on Combine soldiers in an exodus from the wastes.
