The Napoleonic era was a time of political unrest and epic battles played out on an unprecedented scale. It revolutionized the organization and size of European armies through the use of levée en masse (mass conscription.) But the strength of an army finds its roots within every soldier's individual skills.
Napoleon: Total War Imperial Edition on Steam includes the exclusive "Heroes of the Napoleonic Wars" pack. This pack gathers the most superb infantry and cavalrymen who fought during the great Napoleonic battles: 10 exclusive units, which will all make a difference during key engagements, whether using formidable weapons or exceptional tactical skills.
These exclusive elite units become available on the campaign map once you have made a specific technological advancement or own the relevant territory.
