Repairing the Wire

Getting Started
You'll spawn near a building. Go forward until you see a path that leads to the right. Go into the building that's to the left of the road. The right building is completely useless. At the end of the right path are MG42s, so hurry!

Wire 1
Inside the building, you'll find the first wire. Repair it by hitting the use key. After that, you'll see that troops are hiding behind the junk scattered throughout the building. First, go to the left and fire at the MG42 gunner at the end and try to wipe out as many troops as you can. When you feel there are enough troops out, go to the right of the building and run through it, then go back to the left and finish off who's left.

Wire 2
After that, run through the hole the gunner was in and repair the wire. Once it's repaired, crouch and look right. You'll get a prime shot of ruins infested with troops. Most of them like to hide behind the junk, so wait for them to come out or throw a grenade. Keep moving and firing, and you'll clear the ruins out.

When that's done, go to the right side of the ruins and you should a see a doorway that leads to a street. There are troops all over the street and inside the building across form you, so toss a grenade in the building and fire at the street troops while the house troops are occupied. You might have to do this multiple times. After the street troops are down, take out the house troops, then follow the street to a large collection of junk.

Wire 3
When you approach the junk-riddled area, troops will begin pouring in from the other side of the street and will set up and MG42. Therefore, you must get on the left side and slowly approach the other side, raining down grenades and taking out anybody that you see. Remember to stay crouched, or you'll get shredded by the MG42. When you get near their camp, throw a smoke grenade, then run over through it when the smoke screen is up. Wipe out everybody that you see, repair the wire near the gunner, but don't go through he regular building entrance! Instead, keep going until you see a crack in the wall. Go through it.

Inside the building, you'll find troops hiding behind boxes on your left. Take them out, then head forward.

Wire 4
As soon as you get through the doorway, you'll see a troop hiding behind rubble to your left. Take him out, then move forward. You'll see troops firing at you from the top floor of a ruined building. Take out one (there's a respawner in the room they're in), then grab your SMG and go up the stairs. Between the two staircases is a broken wire, so repair it.

Wire 5
The stairs lead to a room with junk in the middle of it. Toss a grenade to the other side and begin shooting everybody with your SMG. When the room is clear, get near the MG42 on the upper-left corner and fix the wire. You'll find a scoped G43 here as well, so take it if you want it. However, this is the only scoped G43 in the level, so don't expect any more ammo.

Wire 6
After that, take a right and walk past the planks into a small house. There will be troops at the entrance, so toss a grenade and/or shoot them before you get too close. When you get inside, take a left and then go forward when the left path ends. You'll find troops in a room across from yours, so take them out with grenades and your SMG. When the room is cleared out, turn right and you'll see another room, this one having two troops hiding behind a drawer. Either toss a grenade to flush them out or flank them. When they're out, turn right and you'll see you're near a sandbag barrier with ruins filled with troops on the other side. Crouch and position yourself so that you're in the center of the barrier. Being in this position will make it so that you can see the troops, but they can't see you. Take them out, then go right and down the stairs.

When you get near the stairs, you'll see two troops below. One is hiding behind a piano on the left, so flush him out with a grenade, then kill him and his companion on the right side. After killing them, go down, take a right, and go down the stairs.

You'll see another broken wire. Before trying to fix it, watch out for the troop that pops out from the right hall. Take him out, repair the wire, and go right.

Getting to the Radio
This time, you'll be in what appears to be a generator room. There are two troops hiding behind two barrels in the center of the room, so watch out for them. When they're dead, go on and take a left. You'll see two troops; one at the end of the hall, peeking from the right corner, and one hiding behind a barrel on the left side. Throw grenades at each of them, then run through the hall and finish off anybody you see.

Inside the next room, you'll find a troop peeking from a left corner on the other side. Take him out, then go to the glowing radio in one of the left rooms. Grab teh glowing sticky bombs near it, then use the radio. It'll tell you that panzer tanks have been spotted in your area, so you'll have to take them out.

Destroying Tank 1
After the radio transmission has ended, get out of the room and look forward. You'll see a door break open and three troops pour in. Take out your SMG and mow them down before they can get off the stairs. Go from where they came from, and enter the next room.

You'll be in a ruined room with a sofa near you. There's usually a troop behind it, so flush him out with a grenade and get him. When he's dead, go to the left, through the hole. Wade through the ruins until you get to the right of the ruined staircase. There are a ton of troops in the next area, so toss a grenade or tow to make them scatter, then shoot anybody you see. There's usually at least one hiding between the ruined wall pieces on the left and in the garbage in the center. Hide in the ruined staircase if you've taken too much damage. When the are has been cleared out, head forward and turn right. There might be a troop hiding behind a drawer on the left, so flank him if you can.

When he's out, go to one of the windows and look left. You'll see a building filled with troops. Open fire on them and take out as many as you can. When you've gotten enough, take a right and run out of the ruins into the building you just attacked. Throw a grenade near the table on the left and shoot the explosive barrels on the left. Soon, you'll see a tank driving up from the front. Run up to it and place a bomb on it's back. You could place a bomb on it's treads, but it'll still be alive until some of your allies come put and throw a grenade inside it.

Destroying Tank 2
After you destroy the first tank, take a left and go forward until you see an opening on the right. Go right, and you'll be in an alley with an MG42 gunner from another street pointing at the alley. Fortunately, there's an opening on the right side, so grab your SMG and run in, taking out anybody near the doorway. Go up the stairs and maul anybody in your way. Turn right, and you'll see a troop hiding behind a ruined table. Take him out, then go back to the previous room, go forward until you get outside, take out your rifle, and snipe the gunner. After that, snipe anybody that's left in front and on the right. When the area is clear, jump off the roof and go forward.

You'll be back near the building that had the first wire. This time, there are two tanks in the area; one in front of you and one to the right. Take the forward one; he's much easier to corner and you don't have to chase him nearly as much as the other one. The one on the right will bolt when it sees you, but don't worry about it.

Go into the ruined building, but watch out for any troops on the right side. Gt to the end of the building, and you should see the tank running towards you. Place a bomb on it's back and run!

Destroying Tank 3
Go back to the tank you ignored earlier and go down the street it went down. There are troops on the left side of the street, so slowly advance and try to flank them as much as possible. If you try to use your grenades on all of them, you'll run out of them very quickly. Stay on the left until you get to a raised staircase with a smoke grenade on it. If you look towards you you'll see a community square filled with troops on the left and right sides. The tank is one the right side. Toss a smoke grenade in front of you and to the right so that both sides won't see you while you're placing the bomb on the tank. When the screens are up, run to the right, find the tank, and place a bomb on it's back, then run. When it's blown up, finish off the remaining troops, and you'll exit the level.
