The smallest Unit Pack, Sand Empires, gives 60 units to Numidian, African, Arabian, and Eastern subcultures.

Eastern Eclipse Unit Pack gives units for Seleucids, Armenia, Pontus, Parthia, and other Eastern faction to a total of 131 units. Rise of an Empire Unit Pack totals to 134 units added to Rome, Carthage, Epirus, Athens, Sparta, Macedon, Illyria, and other minor factions. The largest Unit Pack, Barbarian Invasion, gives 186 units for the Germanic, Iberian, Thracian, Briton, Celtic, Dacian, and other barbarian factions. Radious: Total War includes 455 additional units in 4 culturally themed unit packs (186 in Barbarian Invasion, 134 in Rise of an Empire, 131 in Eastern Eclipse, and 60 in Sand Empires).The purpose of having several smaller mods is so that users can choose from the dozens of options as to which aspects of Rome II: Total War will be adjusted and which parts will stay. Which means that is more correct to say Radious Total War is actually eight standalone mods (4 Unit Packs, Unit Pack Compatibility, AI Mod, Battle Mod, Economy and Research Mod, Campaign Features Mod, and Graphics Mod) that are still fully compatible with each other which collectively form a game overhaul. This mod stays true to the Radious: Total War modding style found in the Shogun II Radious: Total War. Since that time, Radious Total War not only continues to change and grow, but also stays compatible with the latest of various downloadable contents and patches. Radious: Total War acquired a hosted mod forum days after Rome II: Total War’s release on September 3, 2014.
