The heart of Campaign Gettysburg is the campaign system. At each stage of a campaign, players choose from 2-4 operational decisions that will result in a tactical battle to be played out on an expansive map, providing room for maneuver. The campaign is non-linear, with both offensive and defensive operational options available to each side.
Campaign Gettysburg contains a record breaking 314 scenarios, including the historic battle of Gettysburg and battles leading up to and after it. Though every scenario may also be played as a stand-alone, the bulk of the scenarios are integrated into the operational/tactical campaigns, providing a high degree of replay value.
