Well, I think I've got something. After screwing around with the tunnels on High Noon and throwing together a couple smaller maps, I've managed to crank out something interesting looking. It runs okay in splitscreen, and I think it's big enough for 4v4 play. Not really sure how the width of the various areas will pan out, but the sightlines are nice and long, and the ceilings are high enough to permit jumping pretty well everywhere, although you can hit your head on the ramps and in the one corridor. So here's a screenshot; And here are the rest of the screenshots Looks like a few didn't upload. There are a couple areas that aren't clear there. I'll work on some sort of overview, but I suck with sketch-up, so it'll probably be hand drawn. So I'm currently working on making it a little more spacious. It's looking good so far - the center area is fleshing out nicely.
