The basic platform for the Battleground series involves individual infantry and cavalryregiments, artillery batteries, and commanders. All are rated for strength, firepower, weaponry, morale, and movement. As a unit takes fire, it may become fatigued, disordered, or routed to the rear. Players compete against the computer's artificial intelligence or against another player via modem. Players may try a variety of 25 individual scenarios, or refight the entire Battle of Gettysburg. A Fog of War option enhances playing against the computer, as it hides units that are not in direct view of the enemy.
