- Enemy Intelligence: 3
You will start at the top of a hill overlooking a wooded valley area below sitting between you and Makarov's safe house. Start down the path to the left and continue across the clearing flanked by a pair of cliffs towards the trees, as you do a large group of enemies will spring an ambush and you will step near a land mine you will go into slow motion and have a short window of time in which to go prone to avoid being killed by the subsequent explosion.
When you regain your senses, quickly look up on the cliff to the left and kill the rpg troopers here and then hug the wall beneath them as you use it as cover to kill any visible enemies in or around the smoke before you. When you can see no more, sprint forward into the smoke and follow the rock wall around to the left into a smoke free zone populated by a number of tree stumps, immediately go prone and take cover behind these. Defend this area until you feel relatively safe before mopping up any remaining enemy units and continuing uphill towards the house.
As you approach the road leading to the safe house, a pair of trucks will roar past, shoot at them if you like - your squad seems to enjoy the challenge.They are bullet proof, so there isn't a lot of point wasting your ammo and they will be destroyed momentarily anyway. Once they have been explodified,continue up the hill to the house. Nearing the top of the hill, another pair of vehicles will show up and drop of 10-12 enemies for you to kill. Retreat downthe hill to the cover of the nearby trees or solar panels and take them out from here. When it's safe to do so, continue up the hill to the house. Before you breach however, I suggest you head to the back of the building and down the small hill to its rear to find a smaller building with a boat inside, look onthe crate nearby to find Enemy Intelligence (1/3). Return to the safe house.
There are three doors that can be breached from the outside and several more which need to have the same treatment done to them on the inside of the house. I suggest busting through the lowest of the three doors, and letting your other squad members handle the upstairs area. As you breach there will be 4 enemies in the room, another 2 will come down the stairs to the back left to join them and a further enemy or two can be found firing at you from the bathroom down the hallway to the right as you enter.
Once the area is clear, there are two doors to breach in the hallway here, take the left first and kill the three baddies as they try to escape out the back door, then turn around and breach the other door here. There will be a guy infront and a second in an armoury area to the left. Kill them both and enter the armoury, pick up Enemy Intelligence (2/3) here and pick a pair of weapons of your choice before heading upstairs to help breach the remaining locked doors. As you cruise upstairs be on the lookout for any enemies that Ghost and his pals might have missed, before making your way up to the top floor. There is only 1 door here, so clear it of the 4 enemies (watch out for one of them lurking in the bathroom with the blow up doll) and collect the Enemy Intelligence (3/3) sitting on a crate below the windowsill in front of you.
Return downstairs, you will now need to plug in a DSM and transfer the files from Makarov's computer. This will take about 5 minutes to complete and the bad guys aren't too happy about you trying to discover the true location oftheir boss and will send a small army in an attempt to stop you. Before you connect up the DSM you should take the time to prepare. Plant your claymores around the various entrances and hallways to buy yourself some time and when you've used them all, go back to the armoury and pick up another bunch. When the house has booby traps pouring out of its wahzoo and you are ready to go, start the transfer.
My preferred hiding spot for the next part is as good as any (and I'm sure there are better ones out there, but it worked for me on Veteran so I'm happy!). From the computer, look straight ahead. See the two couches on the right wall? Get in between them and go prone, then turn to face the computer from here you can see all three major entry points for baddies: the kitchen behind the computer, the front door and the hallway directly in front of you. Once all the claymores have gone off, you will need to keep an eye on all three portals and pop anyone trying to destroy the computer. It is not too tough, but you will need to watch out as they are pretty keen on their flash bangs, to combat this, just take cover until you can see properly oral ternately throw a flash bang back so they won't shoot the computer whilst you recover. When the transfer is complete, shoot anyone in the vicinity, before grabbing the object and sprinting down the hallway opposite the hiding spot and jumping over the balcony.
There will be a million and one enemies chasing you now, so sprint down the hill and to the left of the small lake here, continue towards the waypoint marker and as you run down the final hill here, there will be a good number of enemies firing up at you from all sides, try to run straight down the hill ruining from tree to tree to grab as much cover as you can before sprinting out into the field below. It doesn't matter if you kill anyone or not, once your each a certain point you will see an explosion and be immobilised. When you come to, shoot baddies as you are getting dragged away and then watch the scene here to complete the mission.
