D-Day Omaha Beach
Since the map is locked, I can't tell you who the author is, but it does say that it is dedicated to all the prople who died on D-Day. In order to win, you have to make it up the beach and kill
all the Nazi leaders. Doing this is VERY hard, as you will lose THOUSANDS of troops in the process. Be sure to get lots of marines to act as cannon fodder while your artillery does the real damage.
