I was bored so here's an update
+added actual cubemaps this time (probably)
+added map icon
+added extra room underground
+added actual lights underground
and other minor things

Big update! This came out quite late because of hammer problems.

+ Added decals around the map
+ Added Cinema
+ Added Prop delivering pipe, along with a building on the surface for it.
+ Made the top area generally bigger
+ Remade surface terrain
- Removed a ramp from the hoverboard park because of size change

Note that any save you've created that has objects on the surface will load floating, due to having to move everything on the surface.

I think this will be the last update for this map, unless anyone has any suggestions.

Thanks for downloading.

woah! update!
Added little hoverboard park
Added water pool thing
Fixed terrain a bit
Added 'door' for the pit along with buttons to toggle
Fixed being able to move doors
Fixed lighting being stupid in some places

with extra spook

Added cubemaps, only on the surface as the bottom of the pit's lighting changes due to most people adding lights.
Fixed missing textures

Created map.
