In this level, you will get off of a truck then make your way to the Nazi houses. When you finish all of your objectives you will need to exfiltrate. When you get past the front gates near the end of the level (where you meet the French woman), kill all the Nazis in that area. Then, sit in between the two sand bag bunkers a few steps from the gate. An unlimited amount of Nazis will appear two at a time in intervals of about three seconds.
