In this file come two random maps: Jungle Island and Winter Island.
Jungle Island map has a bunch of small islands. The map is very tricky because you may start on a gigantic island with tons of resourses, or start on a tiny map with little resourses. You start with a lot of villagers, a barrack, town center, dock, two fishing ships and galleon, and one transport.
Winter Island is just like the map I described above, but you don't start the the small navy. Also, ice surrounds the islands, attaching some, making onland battle possible.
