Cossacks II: Napoleonic Wars is the fourth computer game in the Cossacks series of real-time strategy games, released in Spring 2005 to mixed reviews. This game focuses exclusively on the Napoleonic era, meaning it has a much shorter time span than others in this series, which spanned several centuries. Therefore, fewer technologies can be researched than in other Cossacks games, and there aren't as many different unit types for each country as before.
