I've been working on a couple of things for Rising World, mainly testing out some ideas for a possible map or, hopefully, something I could add into random gen with a mod. Here's a few pictures of the modular underground research facility and a hydroelectric dam, though it's pretty small. The research facility is only one main hall and a couple of offices at the moment but I'll finish it eventually.
The first three images are the research facility, the rest is the hydro dam. The hydro dam itself is inspired a bit by the big hydro dam in a game called Inherit the Earth, although I couldn't get this one looking sci-fi enough.
