Act 1: Pyrenees

Scene 1: Negotiations

Move from the helicopter pad down the stairs to the table with blueprints on it. Here you'll get a mission briefing. Your new objective is to infiltrate the negotiations and wait for Alpha Team. Head out the other door and across the catwalk. Do not enter the next doorway until you are told to do so. When you get the order over the radio, go through the door and kill the single terrorist inside.

Head up the stairs to the door. You can look through the snake cam to see what's on the other side. There are two terrorists. The people rappelling outside are friendly. If you kill them you'll fail the mission. Head down the hall and down the stairs. Head outside and at the next corner are two terrorists standing behind a sign. You can shoot through objects like signs. If they return fire two more terrorists will appear.

Switch weapons to the Sig 552 which has better range than the MP5. Press A to climb over the barrier and head along the walkway to take out the terrorist there. Behind the next door are 3 terrorists, one of whom has a ballistic shield. The next room has several terrorists. There is a walkway above the entrance w/ 1 more terrorist.

Head up the stairs and outside. This walkway is covered by an enemy sniper. He is located on the platform above the far side of the walkway. You can take him out with a well placed shot with the 552. Move to the end of the walkway and use the rappel bar. You'll rappel down one floor to a window. Inside are three terrorists and you won't have any cover.

There are two doors here, but only one opens. Head through this door and it will take you to a hallway with three doors. All three doors go to the same room. Use the one closest to where you entered. There are 3 terrorists inside. If you don't get them all when you first enter, back off and flank them using another door.

Outside are some ropes you can climb up. Move down the walkway and you'll encounter two terrorists talking to each other. Take them out and move to the door. The hallway is dark, so activate your thermal goggles. Go through the next door and up the stairs. The door at the top is wired, so look at it and press the action button to order your team to disarm it.

Head inside and wait for orders to attack. Someone will start shooting, so go ahead and take out the terrorists. The hostages will start running toward you from down the hall, so try not to shoot them. Head through the main room and out to the hallway. Here you'll find some outfitting crates, so stop and customize your weapons, armor, and clothing.

Scene 2: Ambush

Head outside and you'll have to deal with a large group of terrorists. You'll want to use your rifle and use the satellite imaging option to get the location of the enemy. This courtyard is infested with enemy soldiers, You can toss grenades to take out enemies behind cover. Watch out for snipers on the rooftop of the building across from you. The exit is on the far side of the courtyard. This hallway has a door to the left which leads to a science center. Around the first corner is an emplaced light machine gun. You'll want to either flank it by going through the science center or take it out with a grenade.

Move into the science center and you'll link up with some friendly forces. There is a machine gun around the corner; toss a grenade before running forward to take it out.

Go up the stairs and you'll get more information about the situation. Go through the doors at the top of the stairs. There are several soldiers across the way shooting at your through the windows, so do likewise. If you need cover, run to the left side of this walkway to recoup. Enter the building on the other side and clear out the enemies in the first area to reach a Checkpoint, then continue forward.

You must now disarm a bomb. Command your team to disarm the bomb in the middle of the room, and note the location of the machine gun turret on the floor above. When the bomb is disarmed, several enemies will flood into the room. Take cover in the hallway you came in through and take them out one by one.
