Sudden Strike is a real-time tactics (RTT) computer game set in World War II and the first game in the Sudden Strike series. The game was developed by Fireglow based in Russia and published by CDV software of Germany. The player selects a faction (e.g. Soviets, Germans, or Allied forces) and gains control of many varied units such as infantry, tanks and artillery. The games focus primarily on tactics, eschewing traditional real-time strategy resource gathering and base development.
