D-Day Defender Game

D-Day: June 6, 1944, 6:30 am. 160,000 allied infantry troops are approaching the coasts of Normandy to conduct the largest amphibious landing in history. There you are, a lone soldier in a turret. How long can you hold them off?

The game is not beatable, history will have its course, and the Allied Invasion will succeed. But how long can you hold the allied troops off?
