Two years later, the sequel is out, based on the bloodiest single day in U.S. history - the battle at Antietam creek. Each objective has a point value and whoever controls the objective at the end of the battle gets the points. Those points, along with points for enemy kills, determine the winner of the battle. Scenarios range from small skirmishes to full-scale battles between massive armies, depending on your preference and time allowance. Infantry will make up the brunt of your army and is where most of the action is located since they do most of the fighting.
Infantry is grouped into brigades which can be broken down into individual regiments.
Movement of your regiments and brigades is all mouse-driven and there are a number of formations, each with its own purpose. Formations like the road column or maneuver column are great for getting around the battlefield, but terribly ineffective in battle. The line column is the best for fighting, but it isn't very useful to move around, while the skirmisher formation is great to use against artillery but poor against the firing power of the line column. While you can issue orders to individual regiments, you can also issue commands through the brigade commanders, which make it much easier to keep your troops grouped. Commanders are single units with no fighting ability, but they do confer abilities on your infantry.
