We have here a product at a bargain price. Inlcuded here are several huge (usually 7200x7200 pixel) maps that comprise a multi-level near-future sci-fi undersea research facilityuniversity + maps for small submarine craft. Accompanying these maps is a pdf that gives suggestions of how these maps are combined.
While the maps and PDF suggest use in near-future games, I believe that this product can easily be used in Star Wars or similar space-fantasy and sci-fi games. The research facility could be used as a colony also in my opinion. As made, the research facility is suggested to be able to support 400 students and about 100 professors, researchers and stuff.
Change some of the "entertainment venues" to training stations and a couple of classrooms to armories and you can have a soldier training facility for the evil tyrrants your players oppose along with dozens of scientists and labs working to develop weapons etc.
For the price given, this product is excellent and I am eagerly expecting more similar products in the future.
