You can control many things in the battle, but the forces of nature remain unpredictable. Expose your battlegroups to the elements with the Climate Add-On and put their will to survive to the test under the most inhospitable conditions. Choose a season, location, and time of day for your game, and customize each game using a multitude of combinations of weather conditions and dangerous environmental impacts. Nightly skirmishes on a storm-battered seashore or icy cold snow storms in the middle of a city? Uncertain times are brewing. —description from the publisher
