I'm about 95% complete with the new Asteroid Field functionality, so I think it's safe to show off the first screenshot, featuring the view from a ship inside an Asteroid Field.
This screenshot features every type of asteroid except Carbonaceous. There's even an exotic asteroid hidden in there. This is just a small 13x13 section of a field, which can be up to 23x23 squares wide. I'll probably push that up to 25x25 before long since I'm just going to assume that most players will have good screen resolution and if they don't then they'll just have to use the scroll bars a bit more.
