Instructions
Load the "Blood and Iron" mission from the "Mission Select" menu in "Call of Duty: World at War."
Begin playing the game as you normally would, killing enemies as you go. In the first section of the map are six towers and two bunkers. The bunkers are located on the far right after you come around the corner and the towers are sitting in between. Two of the towers are red water towers and the rest are wood.
Move toward the radio tower as directed by the game. Look to the left before you get to the radio tower; there will be another red water tower in the distance and bunker near the trees. Destroy them.
Destroy the radio tower as directed and then destroy the two wood towers on both sides of it. Follow the in-game directions to rejoin your army and then destroy the large bunker in your path and the two towers to the left and east of the bunker. Use the compass in your mini-map to locate the east tower.
Follow your army up the hill and destroy the two towers to the left of the trenches. Planes will now fly over and drop bombs. Watch to see where the bombs land. If they don't destroy the tower they land on, destroy it yourself.
Point yourself towards the north and go as far as you can. Destroy the tower by the concrete rubble and follow the rubble into the train station. The last tower is on your left side as you come up to the station. As soon as you destroy this tower, a message will pop up onscreen saying that you earned the "Iron Fist" achievement/trophy.
