forgot to clip an area, whoops.

Also moved the skybox down, my map still looks very weird. Even for an alpha.

More polish and extending skybox. Cleaned up a lot of the map, completely redesigned the "shack" area to more of a valley.

Further optimization and area portals. Made main stronger, changed layout. Blocked many problematic sightlines, made attacking stronger. Greatly closed distance of map overall, made spawn smaller.
