No campaign, its just MP, but its still really good. A lot of fun, though there is no customizing your guy with what weapons you want him, and there are like 5-6 different kinds of pre-set infantry, 3-4 cavalry, and 3-4 special (usually sapper, artillery, and rocket or something, sometimes commander too.
Battles are fun, but nothing like they advertised. Forget about lining up to take shots, its usually every man for himself. Would love to see a campaign of some sort, though the artillery is really cool.
