This is a Marathon 2 landscape plugin intended for people that like the look of the original landscapes, but want more detail than the originals allow. Most HD landscapes available make fundamental changes, and I've tried hard to avoid doing that with these.
These were created with AI upscaling, and I did some small touch ups to certain landscapes to try to get rid of anything odd. They are probably still not perfect, but the hope is they look the way they're supposed to, and are still improvements over the originals.
Reduced some noise in the moon/space landscapes.
