Cutscene: In the interrogation room, they show Blackburn the video of Solomon executing Miller. The interrogators say that it isn't enough to connect Solomon to the nuke. The interrogator receives a phone call, then says that one of Solomon's aliases just hit the grid in New York. Blackburn says Al-Bashir was very clear about Solomon being his right hand man when he and Campo went after him.
Cutscene: You (Blackburn) and Campo are on a roof at nighttime in Tehran with sniper rifles.
Shoot out the four lights in the parking lot opposite. You need to shoot near the top of the glare to hit the light itself. A friendly helicopter then comes and drops off some soldiers in the parking lot. Move to the right to another corner of the building to get a better view of where your allies will be heading. Shoot the enemy to the right of your allies on the balcony. Follow Campo to the opposite side of the roof and interact with the marked point to rappel down the building.
Follow Campo across the road and hide behind the car until the van passes, then follow Campo further and into an alleyway. Follow the on-screen prompt to climb over the wall. Shoot down the enemy on the balcony ahead, then proceed forwards and into cover with Campo while a group of enemies walks past. Follow Campo around the corner to the right and up a ladder onto another roof.
Proceed to the corner of the roof. Shoot the two enemies on the right side of the street ahead. Once your allies have crossed the road, move to the ladder nearby and go down. Follow Campo through an overpass and left into an alley. Head into the building and up the stairs, then take down the enemy with your knife to initiate a short cutscene.
Run out of the door you are near to and follow Campo into the sewer. Continue forwards and then crouch through the small tunnel on the left, then continue following Campo around to the right. Climb up the ladder back to street level.
Shoot the enemies ahead then follow Campo up a set of stairs to a door. Enter the building to the place where Miller was killed. After some radio chatter, kill the enemies who enter from the other side of the glass. When they are all dead, follow Campo through the doorway, down the stairs and out of the building. Move towards Cole.
Proceed into the mall and around to a door on the other side of the escalators. Go through the door, through some corridors, and out into the street and head to another door. Follow Campo to a ladder nearby and up a ramp into the ruins of a building and onto a ledge.
As the marines advance below, snipe any enemies who might notice them. An enemy walks out in front of them as they head up the alleyway on the right. A vehicle then comes down the road on the left and passes the marine, and they proceed up to the building and use a flashbang.
A firefight then breaks out and a lot of enemies appear from the right side of the screen and also on the ground in front of you. Some will appear on the upper floors. After the marines use another flashbang, another wave of enemies will appear in front of you and to the right. A truck will then appear to the left, so shoot the enemies which emerge from it. More enemies will then appear from the right side, and an enemy with an RPG will appear on the roof. Take out the enemy on the gunner seat on the vehicle to the right. Continue to kill the enemies.
When you hear that Al-Bashir has been spotted and the targeted vehicle appears, follow Campo to the right side of the building and shoot the car. Follow Campo down to the crashed car, where he picks up the injured Al-Bashir. Follow Campo to the gate while fending off attackers. Stay at the gate and take down all of the enemies, then interact with the door to follow Campo inside. Go down the stairs, through the mall and up the escalator to regroup with Campo.
Enemies will soon come from the ground floor entrance, so in preparation place claymores there (on the opposite side of the building, near where you just came from), then return upstairs to defend. Take down all of the enemies. Another wave of enemies will now come from the second floor in the same direction, so take those out too.
Follow Campo to another corner of the building. Another wave of enemies will come from the opposite side of the building, including on the floor above, so take them out. After some brief radio chatter, some more enemies will approach. Take them out and follow Campo out of the mall. Defend the helicopter until your ally gives the call for you to get on board.
Cutscene: You give Al-Bashir a shot of adrenaline. He says that Solomon told him to get the bombs and use them for leverage. He says that Solomon will strike after sunset on the 14th of the current month. Al-Bashir dies, and Campo checks his phone.
