This level is so easy! First, walk along the path until you get past the trees. The, head up on the snow bank, and switch to your sniper rifle. Snipe the guy walking on the path ahead, then aim towards the hut. You should see two soldiers, and some barrels. Shoot the barrels and they'll explode, killing both guys. Pick up the ammo of the three men you just killed. Then, go behind the hut, on top of the snow bank. In the distance, you should see a metal tower-like thing, and a hut facing right. Head towards that hut. There may be some men to kill along the way, so keep your PP7 handy. When you reach the hut, open the door, and quickly kill the man inside. Then, leave the hut and wait by the door. A Siberian Special Forces man shuold come out, so have your PP7 ready. After you ice him, re-enter the hut, and pick up the key the guy has dropped (make sure you also get the grenade launcher!). Now, head over to the satellite dish. Go in the double doors on the right side, and walk up the steps. At the end of the steps, there should be a door. Open the door, and you'll find a large computer. Walk up to it and press B, don't shoot it! Then, exit the dish and head back to the beginning of the level with the two huts facing each other. Go in the hut on your right (which you can now enter because of the key you have). You should see a desk with a large key on it. Pick up the key, it is the Safe key. Now, head back towards the dish. Turn left at the dish, and you'll see two huts guarded by a chain-link fence. You need to enter the hut on the left, the one nearest to the dish. You should see a safe. Open the safe and get the building plans. Now, head back to the dish. Follow the path in front of the dish until you reach another path heading left. Take this path to the ventilation tower. Climb the tower, and shoot the padlocks. Then, jump down into the bunker below. Easy, isn't it?
