I've attached a demo of things you might want to revise. Also, right after I stopped recording, I noticed one of the crates (small one on the first floor of the blue base - maybe others) was floating. Another thing - you might consider making the autococker more new player accessible. If you can get to it, chances are, you're not the one who needs it.
Oh, an one more thing:
In your package, the map should be in the maps/beta directory (so we don't have beta maps cluttering up the regular maps directory). Also, could you put the sound in a sub folder (either one of the existing ones or make a new one for your maps)? I'd prefer to keep sounds out of the root sound directory. What triggers that, anyway? I never heard it.
