History Civil War: Secret Missions review. Classic Game Room presents a CGRundertow review of History Civil War: Secret Missions for Xbox 360. Released in 2008, this game was developed by Cauldron and published by Activision Value. Most games based on movies suck. Most games based on TV shows make you want to throw up. However, what if that game is really based on some of the most action-packed battles in the Civil War and let you play as both the North and South.
