Combat is based on differentials, not odds. Each attacking brigade attacks in sequence, one at a time. If the assaults follow each other closely enough, the defender is worn down from disruption to shaken, rout and, finally, elimination. This is a more accurate portrayal of civil war combat than ganging up on the defender, chasing the magic 3-1 odds. Another change from other Gettysburg games is the victory conditions.
Victory is earned by inflicting casualties and exiting units.
It does not depend on geographical locations. As the map covers an area wider than just the battlefield, players have much flexibility in achieving their goals. This freedom of action means each game will not boil down to slugfests over Little Round Top or Cemetery Ridge etc. The game covers four days of battle in forty eight turns - though much smaller scenarios are provided. However, once the rules are digested, the game moves at a cracking pace.
