The five original Close Combat games were real-time tactical (RTT) wargames, taking place in real time, with a top-down perspective and two-player capabilities. Each was set in a different European theatre of the Second World War. Each game included a mixture of infantry and armoured units, whilst the later games ... included artillery and air support. Although viewed from a top-down perspective, the later games modelled terrain elevation, and included buildings with multiple floors. The overall tone emphasised realism, and modelled the emotional state of the units, including panic, desertion and surrender. Despite the inclusion of bloody corpses, the game was granted an ESRB rating suitable for all age groups.
