You are now on the trail of Makarov, follow your squad as they make their way down the hill, get ready to go prone though as a mine will shoot up out of the ground and you need to avoid its blast. Soldiers will now start to come at you so grab any cover you can while you are taking them down. An enemy smoke screen will soon be released, once it is dart down the left hand side and take out any soldiers in your path, grab cover behind some of the rocks if you need to. After clearing some of the resistance just push your way down the left and towards your marker, you will soon arrive at Makarovs safehouse - kill the soldiers outside the house before moving up to make your entrance.
When you reach the house you need to breach the front door, when you do its same tactics as before - take care of the enemies in the room directly behind the door during the slo-mo before dealing with another two just off to the side. With these guards taken out, move downstairs and there will be a couple of soldiers in the hall, after killing them breach the door on the right - there will be another couple of soldiers in here so take them out. Now come back out of this room to breach the other door, there will be a group of soldiers in here who are rushing out so mow them down before they get the chance.
After breaching the two rooms, move back upstairs, you need to go up another set of stairs right by the front door you first came him to get to the top level. As you get to the top of the stairs a soldier is in the toilet to the right, take him out before proceeding to the left and dealing with the guard in there. You now have another room that needs to be breached, there are more hostiles through this door so take them out once breached.
With this final room now cleared you will soon have to defend the house as enemies come from all directions but you have to connect the DSM to Makarovs computer first so you have some time. There are two places that you will have been through in the house that have large stockpiles of weapons, go to one of them and choose your weapons wisely - we suggest you get one of the big light machine guns (lots of ammo) and also a weapon with a thermal sight attached to it. Once you have chosen your weapons, go around the house and plant claymores at or near as many entrances and doorways you can, as well as a couple around the computer downstairs.
Once the claymores are set up, connect the DSM to the computer, now be prepared for the waves of soldiers that will be coming. Listen out as your teammates will tell you where the enemies are moving from, we decided to keep moving around the house during this section, it enables you to target the different areas that the enemies approach from and you can eliminate most of them before they get anywhere near the house. As your teammates highlight where the next wave is coming from reposition yourself accordingly, you need to watch out for hostiles coming up from the basement as well as through the main doors - any that do get into the house need to be killed quickly.
As long as you keep moving about the house and dealing with most enemies before they get near you should be ok getting through this section although it can be tough on the harder difficulties. Once the DSM has completed downloading, you need to grab it and make your escape, there will be a few more enemies to deal with both inside the house and on your way out so remember again to utilize all equipment and any available cover. When you get the chance you basically just need to sprint towards the extraction point, you will encounter a few more soldiers along the way so deal with any that are directly in your path. As you make your way past this point you will be knocked to the floor by a mortar explosion - watch the cut scene as the story takes an unexpected twist and the level is complete.
