Colossus will be a 2 player wargame simulation covering four historically important sieges in the Ancient Mediterranean world. Syracuse in 414 BC during the Peloponnesian War, Rhodes in 304 BC when it was besieged by Demetrius I of Macedon, Jerusalem in 70 BC as part of the First Jewish-Roman War and the siege of Antioch in 1097 during the First Crusades. The game will use a new unique system to deal with such important factors as morale, supply and disease for both sides.
