Recently I've been making a lot of progress with my 3D engine, and therefore the game utilizing it, Contention. Most of it is stuff that you won't notice like tweaks in draw distance and focal length. Notably, though, it has crosshairs and a zoom button (the beginnings of a HUD), planets and these rings:
These rings (which may be a space 'road' to major places in the final game) are currently the most complex object in the game. They're great for testing the upper limits of my 3D engine. Also, the zoom view has a night vision effect, as shown below, and the AI can now shoot.
