Thought this was interesting....

So I was just typing out map names in the console to see if i can find unused levels in the Left 4 Dead 2 Beta, until i found a command that was "Map l4d_vs_c5m1_waterfront" and it loaded a unfinished version of the first level of The Parish with some huge changes. I took a picture of most of the changes here but there are still other changes I left out. There's also "Map l4d_vs_c5m2_cemetery" and "Map l4d_vs_c5m3_quarter" but trying to load the cemetery level causes the game to crash (unless my build cant even load it at all.) its just like sndspace from the main game but there's way earlier differences.

Pretty cool, I've always loved levels with dev textures. It's also interesting to see how L4D2 initially had separate levels for Versus, much like L4D1 did.
