Return of the Obra Dinn, the most recent game by Lucas Pope of Papers Please fame, comes recommended as a story puzzler. Curiously the 3D game uses the Unity game engine but rendered using only two colors with dithering. Apparently, this has been dubbed Ditherpunk. post 
Lucas Pope wrote a forum post where he explains which dithering techniques he uses and how he applies them to 3D space. He put extensive work into making the dithering stable when camera movements occur. Reading that forum post kicked me down the rabbit hole, which this blog post tries to summarize. post
The post goes on to explain various dithering algorithms with examples applied to a mostly dark and a mostly light image. Light versions shown here.
Look for detail or absence thereof in deck and tower cross-braces, the gradient in the sky and water and the boat's wake. Magnify the page or view-image-source if you think scaling interferes with rendering.

Dithering is usually aligned with the viewport or uncorrelated entirely. I developed a bit-map painting technique called Toothpaste Graphics where the dither was aligned with the brush. This allowed me to render 3d images in left and right views where the visible texture made sense and enhanced depth perception.
