The game uses a top-down battlefield map divided into terrain areas and unit positions. Players command one side in alternating turns, moving formations, selecting attacks, and managing the consequences of orders across the Gettysburg battlefield.

Scenarios focus on historical situations from the campaign. Objectives depend on the selected scenario and may involve holding important ground, taking positions, or inflicting greater losses than the opposing army. Progress comes from controlling terrain and preserving effective units rather than from an economic or technology tree.

Use terrain and elevation to strengthen defensive positions, and avoid dispersing formations without a clear purpose. Preserving organized units is often more valuable than making isolated attacks.

Study the scenario objectives before committing reserves. Coordinate attacks against one sector, protect exposed flanks, and account for the delay between issuing orders and seeing their full battlefield effect.
