First, go to the building on fire and get the health pack. Then, wait until the tanks kill everyone and blow up the building entrance. Go inside and get the two health packs. Kill the man with a Panzercheich. Go outside and stand in front of the M12. It will not go anywhere. Get to where you can snipe enemies with the M1 Garand and where they cannot see the M12. Go get the health pack by the city gates and pick up any left over from the battle. Around the corner is a room with a Panzercheich and a health pack. Down the street are more Panzercheich launching Nazis. Stand in front of the M12 and snipe the Panzerschrecks again. Ease around the corner and there will be a building where about twenty five enemies will come out from. Set and snipe them. Go to the end of the street and into the building to kill two more anti-tank soldiers. Go in the basement and get a checkpoint. Then, go through the tunnels and get to the machine gun. Kill all the Nazis until the theater is blown up. Once they are all dead, go down another set of stairs and out the door. There are two Nazis with Panzercheichs where the machine gun is located. Kill them and go down the sewers to complete the level.
