Just came across a new danger room while I was spelunking the clockworks this evening.

Monster waves consisted of Zombies, Kats, Retrodes and Mecha Knights.
Someone can post that screenshot and info to the wiki, I don't think steamies are allowed to edit the wiki yet.
I recorded a video of it as well, I'll post about it later in the general forum once it's encoded and uploaded.
This is my type of danger room.
Are there any turrets?
