Chapter 10: Berlin Catacombs
3:2: When you cut through the first gate you come to, drive forward a wee bit and look to the left to see a pipe in the side of the rock that is blowing out bubbles. Just to the right of the pipe will be a small opening that you can swim through. Follow the passage and it will eventually lead you to a small room where you can find this code piece on a table near the back of the room.
3:3: Once you raise the water level in the sewer, go through the door you entered to get to the switch and then swim across to the other side where the broken ladder is (to the right of the tunnel). Go through the door and up the ladder to find the code piece on a crate.
3:4: After you have raised the water, reached the platform and jumped in to the water on the other side, set the mines loose and go through the destroyed grate. Once through, take the stairs on the left and on the platform there will be some crates with the code on it.
3:5: Continue swimming through the tunnel as far as you can (assuming you released both mines) and there will be another set of stairs on the left. Go up to find this code beside a door.
3:6: Cut the chain on the door beside the previous code and go through to the large grate that has an opening in it. Drop down to the ledge below and then crawl through the small tunnel. Go through and climb the ladder in the next room. At the top will be this code on a shelf.
3:7: When you reach the train station, look under the first set of stairs you come to and you will see the code piece sitting on the ground.
3:8: Go to the large garage door to the left side of the station and to the right of it will be an open door. Go through and you will find this code on a shelf in the small room.
3:9: At the very end of the chapter, to the right of the switch needed to press will be the code on the panel.
