Mayak Facility is a large-ish macro map with three possible third bases–a King Sejong style high-ground base with a vulnerable mineral line, a close forward base tucked close to the main, and a slightly further away base in line. After that the bases flow pretty normally. The middle of the map has a bunch of roundabouts to break up army movement. Otherwise the map is pretty self-explanatory.
I also ran into some editor weirdness when making this map (being unable to remove that weird black blotch that appeared in the middle of the map, and fog not appearing when exporting the map image), so if anyone knows how to fix that, I’d be grateful.
