Keystone Company is a Black Ops unit that appeared in Resistance 2, especially in Twin Falls, Idaho and Chicago, Illinois. The first time Keystone Company are seen is while making your way to the North Tower in Twin Falls where their corpses, and Spinner Pods are strewn along the bridge. It is believed that Keystone was there to protect Twin Falls, and during the ground assault told the majority of the civilian population to hide in a train tunnel. When the Chimera attacked all the population in the train tunnel were infected and the few survivors, with the help of Sentinel Team Lima, tried to stop the Chimeran forces and activate the tower.Sadly,they all died trying.
