Discover the famed Cu Chi tunnels, an interconnecting network of subterranean passageways under Saigon used during the Vietnam War to evade the American military and stage campaigns such as the infamous Tet Offensive. Crawl through the enlarged tunnels; during the war, Viet Cong guerillas would live in the tunnels for days, emerging only to re-supply or to launch attacks. As a result, the tunnels became a miniature city, complete with barracks, supply larders, weapons stockpiles, medical wards, and the like.
