This one is a nearly complete map. So don't worry about the beta version. Only one texture is out of place and if I one day have time I will recompile this map.
There are many secrets in this level. Read the info text that load when you start the map for more information about them.
Enjoy!
UPDATE: 7-20-2009
I am not able to add more screenshots so I have some pictures on photobucket of a few key secret area's that might be super hard to find.
I also made sure you wouldn't see the hollow areas on the boxes by making the whole box a func_illusion and making a second func_wall box inside of that box. End result, you won't see any funny looking places on my hidden areas. You can shoot to find them, also when players respawn, some boxes may open or close.
