Sid Meier's Gettysburg! is a real-time game, simulating one of the most dramatic battles in history. An accurate Gettysburg battlefield, 3-D units, and historically correct scenarios place you in command of either the Union or Confederate army. Challenge your friends in various multiplayer modes.
Once you have installed SMA, you must also install the Antietam_Beta_Patch_v2.0 to your SMA game in order to play the add-on battle packs. Note: If you are installing Sid Meier's Antietam (SMA) on an XP Operating System, you will not receive sounds for the game unless you delete the following two files from the Sid Meier's Antietam main game folder. The "cfgmgr32.dll" file and the "setupapi.dll" file.
