Plot
David starts out in a MRAP cruising through Highway 110 under siege by drones. He sits opposite of a heavily wounded person (labelled 'secretary' without capitals) being attended to by Harper. To his right is the U.S. President, concerned about the city's condition. Mason checks his Wrist Pad, readies his KAP-40 and looks through the window. As they are passing through traffic, citizens are being evacuated by a police helicopter hovering overhead while drones invade Los Angeles. An incoming missile hits the helicopter, causing it to crash onto a military convoy entering the city below. Debris flies towards the truck, causing it along with most of the convoy to crash. David blacks out and when he comes to, he sees Harper giving orders to the agents, telling them to stay down. David climbs out of the wreckage as Harper tells him about a mobile SAM turret that they could use that had crashed on the other end of the road. They make their way to it. David jumps onto the hood of the car and nearly falls off, he regains his footing and mans the turret. He takes down the drones that attempt to circle the president's location. Once they are taken down a missile hits the SAM, disabling it and breaking the ground beneath. Mason jumps out and watches it fall, he turns back around and sees a drone coming for him. It was then shot down by Anderson, crashing down and narrowly missing him. Anderson arrives and provides close air support. Mason gets up and regroups with his squad at the end of the highway, he can choose whether to snipe from the highway or to rappel down. Either way, he picks up a Storm PSR and fires at enemies hiding within a crashed truck, behind a column and approaching enemies. As they reach the second convoy, Mason regroups with the team. He drives the president out of there while the freeway falls apart, running down any opposition. Anderson takes down the drones trying to get near them, and blasts the debris blocking the tunnel. As they travel through the destroyed roads, Harper mentions Menendez's attack on the Pentagon, Washington, and Wall Street from the previous days. As David turns to reply, a truck is seen rushing towards the two. The screen blacks out.

The screen fades back to David recovering from the impact of the truck, and he climbs out of a hatch in the roof and fights his way down the street with Anderson still providing cover fire, destroying C.L.A.W.s along the way. At the end of the road he reaches a plaza in downtown with LAPD officers and his SEAL team, machine gun nests have them pinned down so they decide to bypass them through a mall to the right. Quadrotor drones arrive and David uses them to distract the machine gun nests and help clear out the mall. They come out onto the balcony and kill the enemy snipers and gunners in the nest. Anderson gets on the radio and asks for help, her last wingman is dead and the presidential convoy is taking heavy fire from all sides. David promises relief and advances down an alley, and onto a road with his squad. Anderson says she is hit and has to settle the jet down. They advance down while taking down tangos towards Anderson but a building falls down their immediate front. Mason blacks out for another time and gets up. Anderson is no longer talking.

They reach her FA38 to see her unconscious body next to it. LAPD arrive and bring her to an ambulance. Harper follows inside while David, not even knowing how to pilot it, mans the FA38 and follows the ambulance. They head towards the president's convoy and take down enemy troops, drones, armor and emplacements that threaten it. A drone garrison attacks the convoy and David detaches from the convoy to chase them down, locking on and firing. The president reaches the evacuation point and the mission ends.
