- Enemy Intelligence: 4
This mission starts out on a helicopter flying in to assault a prison housed in an ancient castle, good stuff! After about 30 seconds or so of taking in the gorgeous scenery, our metal chariot arrives at the Gulag and it’s time to get down to business. The helicopter will stop and hover between two towers and conveniently enough, both towers have several soldiers stationed on top with RPGs, pull out your sniper rifle and take out the guys in the tower in front of you, before looking left to take out a couple more rocket toting baddies.
Following a quick scene, the helicopter will land in the central courtyard to drop you off. Follow the allied soldiers under the boom gate and take cover. Use your sniper rifle to remove the enemy soldiers on the rampart and various ledges to the west. Once they are down, move up to the AA gun here and use the sniper to remove any soldiers high up to the southwest before concentrating your firepower on the ground troops in the same area. As you move closer afriendly helicopter will show up to help you out briefly. Use the distraction to snipe the enemies (including a pesky RPG guy) on the wall behind the barbedwire fence in front of you. When the area is clear move through the gate into the next zone.
Follow the squad through the archway to the right and defeat any enemies trying to get up the stairs to the southwest. When safe to do so, climb the stairs and look inside the room here for Enemy Intelligence (1/4). Return outside and head through the red gate nearby to enter the prison. Make your way down the stairs and into the control room killing any enemies brave enough to get in your way. As soon as you enter the room here, go to the opposite side of the area to find Enemy Intelligence (2/4).
Follow Soap and the rest of the squad down the stairs and fight your way from cover to cover along the circular rooms here, making sure to clear the open cells and continue until you reach a locked gate. Defend your position for 30 seconds or so and Ghost will open the next two gates granting you access to the next few circular rooms. After reaching the next locked gate, wait for it to open, then turn left and sprint to the armoury area just below the control room. You will have to defend this small room and because of the number of enemies firing at you, there will be very little opportunity to fight back. So grab a riot shield, crouch, put your back to a crate and sit there blocking shots until the door is opened.
Ditch the riot shield and follow your squad across the bridge here, stay close to them as they will still have shields equipped and will take most of the bullets coming your way, making it easy for you to pick off enemies in front of you and your posse. As before make your way around the circular areas here clearing the cells as you go. Note that between the first set of gates, look in the cell to the right to find Enemy Intelligence (3/4) on a desk. Exit and continue along the circular rooms until you are instructed to rappel from a window. Do so.
At the bottom, head across the room and down the stairs into the darkened area below. Put your night vision goggles on and follow Soap, clear the first cell corridor of the 7-8 enemies and then be sure to clear the cells on either side. Exit into a long corridor and continue through the door on the left at the far end. Turn left round the corner here and eliminate any hostiles in the maintenance rooms here. And prepare to breach and clear.
About half way down the next corridor you will find the breach point on the left wall. When ready breach away and head inside. Quickly take cover to the left or right as you enter and use the relative safety to clear the ground troops in the immediate area before turning your attention to the hordes of enemies on the balconies overlooking both sides of the room. Slowly move up to the second room here to see another group of ground level enemies come to join the party, this time including several soldiers with riot shields. Again, the balconies will fill with enemies to compliment the new reinforcements below.The best bet here is to fall back to the area where you breached the wall and try to lob a few grenades as the shield baddies advance to try and remove the riot shields from the picture as they are not much fun to contend with up close, and then pick off the remaining enemies as they approach.
When the room is clear, head to the very opposite end of the room from where you entered and drop down the hole in the floor. Follow the tunnel straight ahead until you reach a dead end, then jump the fence and slide down to the next tunnel below. Breach the indicated wall here to see a short scene. After recovering, turn immediately left and look at the desk in the corner to pick up Enemy Intelligence (4/4).
As you had probably gathered by the rumbling and shaking, the building is coming down. Follow your squad as they head for an exit. When you reach the open area with the unexploded bomb sitting in the centre, step up to it, watch the scene unfold, then run over and use the action button on the rope to complete the mission.
