Shock Force depicts fictional battles in the year 2008 between the Syrian Army and US Stryker Brigades. This is the original incarnation of Battlefront.com's Combat Mission series using the new CMX2 game engine. Shock Force features improved graphics and 3D modelling. Modelling of infantry features a 1:1 representation, where every single soldier is depicted in the 3D world by its own animated graphic. The new engine also features real world lighting conditions, and models sun and star positions in the sky. The engine allows the game to be played in real time in addition to the established 60-second incremental format.
Each scenario in the game contains forces drawn from either the US or Syrian Regular Army units utilizing Soviet-bloc equipment such as AK-47 assault rifles and T-72 tanks, with "blue vs. blue" and "red vs. red" scenarios also possible. "Insurgent" units are available as a sub-selection, representing guerrilla forces drawn from the Syrian population.
