I have 1 week holiday at the moment, so I might actually finish this. Spent most of today mapping because the weather sucked.
Would have liked to try some of Sock's ideas, but decided to keep it simple. It's subtle, but the fog makes a big difference.

r_speeds have gone crazy. Was hoping to put some more detail in, but maybe it's already too much considering the layout is annoyingly open and impossible to vis. Getting the gameplay tweaked is probably all that remains (probably should do gameplay first, huh?)
