Sid Meier's Antietam! is a real-time computer wargame designed by Sid Meier, the co-founder of Firaxis Games, then released in December 1999. It is the sequel to the 1997 Sid Meier's Gettysburg!
The game allows the player to control either the Confederate or Union troops during the Battle of Antietam of the American Civil War. It can be played as a single scenario, or as a campaign of linked scenarios, either recounting the original history or exploring alternate possibilities.
The game was not released through retail stores. The staff of Computer Gaming World summarized it as "a grand experiment by Firaxis to test the popularity of online-only distribution for commercial releases."
