Here's the layout for a map I've been working on. Red dots signify resource nodes.
This map is rather large, but I tried to mesh the cramped spaces and wide areas together. It will be interesting to see the result. Also, I'm working on something to put in the lower left area, connecting the marine start to the leftmost hive in some way. Also I need to do all the vents, but I have a pretty good idea of how they'll be interlaced.
The screenshot doesn't really explain everything, because there's a rather large drop in elevation about halfway down the map. The result is a really long elevator, a really long ladder, and general sloping terrain on the right hand side of the map.
The map concept is a SPACE SHIP. Actually, it could be basically anything, because I haven't textured it yet.
I'll have a balance test alpha ready by tomorrow, most likely.
