    1. You start off in the water as Frost once again as you’re paired with Sandman. Wait for Sandman to break through the grates, and ride the submersible as you head into a tunnel. Press “W” to move forward and use the mouse to steer. Move through as you pass by the remnants of battles past, then turn right out of the tunnel into more open water.

    2. Follow the squad while diving underneath the pipe. You’ll then get word of the Russians laying down mines, so check your sonar periodically to locate them. Keep moving through and avoid the mines you come across. As you press forward you’ll head down, and some more mines will be visible. Keep heading down past the chains that are keeping the mines steady and under another pipe.

    3. Then in a scene that reminds me of Star Wars, you’ll see the submarine you need to board, jet past, above you. When the squad moves, move forward as well toward the way-point. Get close to it, then press “F” to plant a mine on the submarine. When the mines blow, the submarine will move to the surface. It’s time to head up to the surface as well. And what a lovely surface it is.

    4. As you make your way on top of the submarine, take out the enemies that are running toward you. After laying waste to them, follow Sandman as you both enter the hatch by pressing “F”. Sandman will open the door when you head inside. Take out the two bad guys directly in front of you and move toward the entry way adorned with the red light.

    5. As you enter, make a right and move down the stairs. You’ll see Sandman using his strong foot once again. Walk down more stairs and you’ll enter an area flooded with water as you hang left. Shoot all enemies in the area as you head to the way-point. You’ll split again from Sandman, so take the stairs on the left hand side. When you reach the top, head right and a pipe will start emitting steam. Then head left up the stairs past the steam, and you’ll be faced with enemies using laser targeting.

    6. They should be easy to locate. Just follow the path of the laser and take all the guys out in the room. When this room is clear, head into the door with the way-point on it, but watch out for enemies in this corridor. There’s also an enemy you can see on the second floor through the grating. Kill any that oppose you, then make a right past the railing, then left as you see a set of stairs to climb.

    7. You’ll be met with a door, but that’s okay because you’ll be breaching it with a charge. Press “F” to do so and Sandman will do the rest. When the door blows, it’s slow motion time. I’d recommend taking out the closest dude. The one who is trying to stab you. Then clear the rest of the room. After some communication, press “F” to use the console. After turning the keys, follow Sandman up the ladder, then head down to the raft.

    8. You’re in full control of this thing, so press “W” to move forward and the “A” and “D” keys to steer. Follow the raft in front of you as you head through the war-zone. At one point, a slow motion moment will ensue with a boat knocking you off course. Shoot the mines toward the back of the boat to continue. Keep following the squad in front of you. Eventually the exfil helicopters will arrive, soaring above you. Punch it, as you head inside one of the helicopters that has landed.

    Protip: If you make a text walkthrough make it all encompassing. This means without deferring to the video with “watch what happens now” and the like.

    The whole point of a text walkthrough is to replace the visuals yes ? Some people may be tethering the internet from their phone and with download limits and poor reception dont have the luxury of watching the video.

    Hi…stuck on Iron Lady….never saw tanks on the bridge, I get two trucks. when I use the javelin I can only lock on either the helicopters or the trucks….each shot with the javelin at helicopters hits the tower, not the helicopters…then I kill wave after wave of troops coming across the bridge, after about 30 minutes, no more troops come over the bridge…but nothing else either, and I never get picked up by the good guys. Volk is still alive…
    Any suggestions? Thanks!

    Hi Chris,

    The videos are only supplementary, you never need to watch them to see what needs to be done in the game, it’s all in the text. I know that not everyone wants to watch (Or even has the ability) to watch the videos.

    ‘Click’ or ‘klick’ is military jargon for ‘kilometer’, which is one thousand meters.
