High Quality Content by WIKIPEDIA articles! Combat Mission is the name of a successful series of computer games simulating tactical battles. The series has progressed through two distinct game engines. The original game engine, referred to as `CMx1` by the developer, Battlefront, powered a trio of games set in the Second World War. Combat Mission: Shock Force was released in July 2007 as the debut of the `CMx2` game engine. The Combat Mission games are a 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.
