The US is at war. Russian Communists have risen out of nowhere and attacked the US on our own soil. Within 5 days of the first attack wave, 25 million Americans are dead. The US has employed all of their Special Forces units against the threat, but nothing has held the Russians off so far. Sergeant Gerard "Bullets" Way is the commander of the US Army's Special Forces Deltas. His squadmembers are Sergeant Frank "Revenge" Iero, a sniping expert; Sergeant Ray "Danger" Toro, a heavy weapons specialist; and Corporal Michael "Black Parade" Way, Gerard's younger brother and a stealth fighter. Together, they must find a way to stop the Russians, by any means necessary.
