Walkthrough
You start where you left off in "Second Sun." From the bunker, your team emerges onto the South Lawn of the White House and meets up with Colonel Marshall. The Col. explains to Sgt. Foley that they're looking at the "high ground," seeing the American flag still up on top of the White House, which has been severely damaged and fortified with spotlights and machine gun nests. With power still in it, the squad should be able to talk to Central Command if they can retake the building. Sgt. Foley leads his team over the left flank to reach the West Wing. The machine gun fire will make it difficult to advance, especially on the harder difficulties, but destroying the searchlights does help make the gunners less attentive to you. Hearing from a speaker behind a painting in the Oval Office, the team has just 2:00 minutes before the Air Force initiates the "Hammerdown Protocol" and flattens the city in order to take out the Russians. The strike will be aborted only if green smoke is spotted on the roof of the White House. You then fight your way through the building and successfully reach the roof in the nick of time to pop green flares signaling the Air Force to abort the fire mission. As you look out at a burning Washington D.C., you see other buildings marked with green flares as the sun sets behind the Washington Monument. The battle for D.C. may or may not actually be won at this point.
