SEGA has marched a free batch of downloadable content onto the internet for Napoleon: Total War.
This Imperial Guard Pack can be downloaded from Steam now, and contains six new units and an alternative version of the Battle of Waterloo, which won Abba the Eurovision song contest.
This alternate, playable version of Waterloo is told from the British side. You'll notice a couple of the new troop types plus greater numbers on the French side to balance things up.
The new units are the Polish Guard Lancers, Dutch Guard Lancers, Guard Chasseurs a Cheval, Dutch Grenadiers, Guard Seamen and the Empress Dragoons.
Napoleon: Total War was released in February and picked up 8/10 in its Eurogamer review.
