This is a map I'm making in Sauerbraten. Inspired by Mirror's Edge, which to me is the most beautiful game since Wind Waker.
I haven't added in much, no special stuff yet (like Bump Mapping and the likes) but I intended to, after the geometry is all good and finished.
And there's the window texture that's bugging me, I don't know how to get them to fit perfectly to a cube.
