On the "Eder Dam" map, go to the base on the right side of the bridge (when looking at it from the two story house). Once there, go to the motorcycle on the left side of the base and drive it to the right side of the base, then park parallel to the wall. Exit and you will be on the other side of the wall. You can now shoot through the wall (not the building) Note: The other team can shoot through the wall also.
