Some people should play before the rate this. It looks nice from the pics but theres quite a lot of problems.
-make "prop_physics" "prop_physics_multiplayer" instead.
-Your soundscapes seem to be triggered at awkard times. I was running through cave and when I reached the end the wind sound was triggered.
-Don't have the same fade distances i.e. 200 and 200. You have a couple of lights that fade out immediatly after 5 feet away.
GJ tho, I'd like to see an improvment of this in the future.
