Modern Combat 3: Fallen Nation — The game's backstory involves the formation of a terrorist alliance in Russia, Pakistan, and North Korea (K.P.R.). General Popovich (one of the Antagonists of the second part), takes control of the alliance and declares war on the United States.
The game begins in Los Angeles, where Corporal Walker, as part of a small squad, infiltrates the NSA building to steal important intelligence data. The protagonist's partners die, but the mission is completed successfully. Walker tries to escape from the building, but is prevented from doing so by heavy fire. The hero teams up with Captain Turner, with whom they attempt to escape from the collapsing building. Already on the street, the building falls and showers the soldiers with debris, but the hero survives and is saved.
