Sudden Strike is a World War II real-time tactics game released by CDV Software and developed by Fireglow. Players command Soviet, German, or Allied forces in combat scenarios that emphasize tactical decision-making over resource management and base building. The game features realistic military physics where terrain, buildings, and environmental factors affect unit performance and combat outcomes. Units can take cover in buildings, conduct reconnaissance, and require repairs when damaged. The expansion pack, Sudden Strike Forever, adds historically authentic units like the 1944 T-34 tank, new desert and snow environments, plus additional campaigns focused on specific military operations. The game includes multiple scenarios across various theaters of war, with players managing combined arms forces of infantry, tanks, and artillery while adapting to battlefield conditions and limited resources.
