"Combat Mission is a series of computer games simulating tactical battles. CMX1 is the original game engine, which was used to create three games set in the Second World War. CMX2, the second generation game engine, was first unveiled with the releas in July 2007 of Combat Mission: Shock Force. The Combat Mission games are a unique mixture of turn-based strategy and simultaneous real-time execution. The game environment is fully three-dimensional, with a "Wego" style of play wherein each player enters their orders into the computer simultaneously during pauses in the action, and then are powerless to intervene during the action phase. More familiar turn-based games use an "I-go/You-go" system of play." The game engine has evolved to also include real time play.
The 2.0 version of the CMX2 game engine will debut with Combat Mission: Fortress Italy in August 2012.
