- Enemy Intelligence: 3
You start the mission atop an icy ledge several hundred meters above the ground below next to our old buddy Soap. After he finishes his cancer stick, follow him along the ledge and use the trigger buttons to climb the cliff. At the top, follow Soap in jumping to the right and continue up the small raised platforms to the left. Soap will prompt you to open your heartbeat sensor, which is quite handy – acting like radar and allowing you to see nearby hostile elements.
Follow Soap along the icy path, twice you will have to stop and kill enemy patrols. Soon after the second patrol you will see the enemy base you have to infiltrate on the left. Follow Soap until you see a waypoint pop-up to reveal the main entrance to the compound. At this point the snow will pick up, making it very difficult to spot enemies, enter the heartbeat sensor. You should move slowly through the next area using the sensor to either kill or avoid enemy units.
Please note, there is an achievement/trophy to infiltrate the base and plant the explosives on the airfield without being detected or killing anybody. Soap killing people is OK, but if you kill anybody, you will not get the achievement/trophy, I personally got it using the below strategy so I hope it works for you too!
Before you enter the base however, you should be able to make out a guard tower directly in front of the entrance. Kill/avoid the patrolling enemies in the vicinity and climb the ladder here to find Enemy Intelligence (1/3) sitting on the catwalk here. Jump down and sneak inside the gate. Immediately turn to the left and follow the fence, make your way forward slowly and let Soap eliminate any bad guys that come close enough. Continue along the fence and cruise around the building that blocks your way, hugging the left wall.
Keep following the fence until you see a short set of stairs to the left and acrate to the right, if you climb the stairs and make your way around the back of the building here, you will find yourself facing the air strips about 30 meters from the fuelling station we need to sabotage for our current objective. Look to the left and follow the fence along until you reach the fuelling station. Plant the charge to complete the objective. A new waypoint marker will appear – you will need to make your way to this location to rendezvous with Soap. As before, use your heartbeat sensor to avoid enemy units as you make your way across the runway.
As you jump down the small ditch between the two hangars to meet Soap, turn around and go to the hangar Soap is not standing in front of. Look in the windows here and smash the middle one to grab Enemy Intelligence (2/3). Head back to Soap and enter the hangar. After a particularly brutal takedown, Soap will order you to head upstairs to recover the objective. As you do, Soap will radio you to tell you he’s in a spot of bother. Crouch and hide behind the crates at the top of the stairs to see the scene unfold below and when instructed detonate the charge you planted on the fuelling station.
As the explosives go off, you will enter a brief slow motion event and as the enemies are all temporarily distracted, you can use the opportunity to mow the vast majority of them down. Follow Soap out of the hangar, and sprinting to the left, kill any enemies close enough to do any damage and then Soap will tell you to make a run “to the east” an objective marker will appear head to the indicated spot to be informed of the presence of snowmobiles kicking it in front of you – they can be quite annoying so try to take them out if possible before moving on.
A new marker will appear in the distance, follow it and ignore the fire you take from a distance – only worry about close quartered enemies for now. Continue following the waypoints and then slide down the indicated hill. Quickly take cover behind one of the small huts here (the one to the right being the better option due to the fence and the crates that prevent the snowmobiles from circling around) and eliminate the soldiers that try to pick you off from the top of the hill and the riders operating the pair of snowmobiles that come down to deal with you.
Once they are dead, hop on the indicated snowmobile and follow Soap to the end. Look out for the first fork-like area during the snowmobile chase, slow down and cruise up the middle to find the last piece of enemy intelligence (3/3). There is very little challenge to the next area, simply follow the set path, don’t hit any trees, shoot any snowmobiles that try to cut you off and strafe back and forward across the frozen lake to avoid the helicopter fire. At the end when you are accelerating downhill, try to stay in the middle of the area and make sure you hit the jump straight on or you will go sailing off into the abyss below. When you land on the other side, continue up the hill to complete the mission.
