This is a Stronghold Crusader Recreation (to the best of my ability) of the infamous D-Day (The invasion of Normandy.)
It mostly uses ranged units, to give the feel of 'bullets' and to put the walls and bunkers to good use.
The Normandy defense is based off of a couple of maps i looked at, as well as trenches that were used. I also used some tips from MapMaking 101 to create "u-boats" on the beach.
Kill the enemy lord, and watch out for those mortars!
