In a conflict that lasted 11 years and claimed more than three million lives, four men experienced the longest 28 days of their lives.
Cut off behind enemy lines during the 1968 Tet Offensive with no way to contact help, four barely-trained young soldiers realize their only hope of survival is to head into the heart of darkness.
Now, with dwindling rations and ammunition, you must guide these soldiers through 100 miles of unforgiving terrain swarming with unseen enemies.
As you drive a wide range of vehicles, shoot era-specific weapons, and evade enemy traps, remember - you're not trying to win a war - you're just trying to make it home alive.
