Sung Island is an official skirmish map from Supreme Commander. Sung Island has certain strategic locations on the map's ridges around the center controlled by civilian gun emplacements that each have one T2 Cybran Point Defense and two T2 Cybran Flak Artillery positions. In the center there are several civilian buildings guarded by several T1 Cybran Point Defences. The set up of Sung Island allows naval chokepoints to be easily built.
