Its 85 mb and it improves naval battles. New skins for ships and wind has more realistic effect on ships. Also ranges increased slightly for all shots. Mainly pointing this out for Sloop but I would like if we played some naval battles once in a while. The download has a self installer with a desktop launcher and it will not have any effect on NTW3.
