The third Civil War title in the popular Battleground series, Battleground 5: Antietam puts players in control of Lee's Confederate army or McClellan's Union army in one of the war's most decisive battles. In addition to the historical scenarios recreating the battle, several "what-if" battles can be waged to see how history might have played out had certain factors changed. The bloodiest battle in American history, Battleground 5: Antietam will test the tactical skills of even the most seasoned generals. As is typical for the Battleground series, the battlefield is divided into a series of hexes and play proceeds in a turn-based manner. Each player has a round to move his or her miniature troops and units and perform desired actions. Numerous video and sound clips improve the game's atmosphere, and multiplayer support lets two armchair generals go at it head to head.
