New portal 2 secret?
I don't know if anyone else has found this yet, but as I was playing the developers commentary I came upon a room that has a ratman den. I though "Hey, I haven't been up there yet." And headed up there. After I got up there, there was a bubble that you can click on to hear the commentary. When I clicked on this bubble... it wasn't a commentary. It was like a signal you got in Final Transmission.
This room is located in Either chapter 3, or chapter 4. It was the room where you must used the light bridge to get to the ratmans den.
If this has been found, then nevermind. Just forget about the post.
But if not and you're making a video, could you please credit me on finding this?
Thanks for taking the time to read this. -

This has been found a long time ago. It's a audio message that creates a picture of the companion cube on the moon.
That's not the one I was talking about. Read the OP again.
maybe you should add a picture?
Is it the one level where you have a cube and a hard light bridge and you need to get up with a lift?
I've got no idea what you're talking about and/or if it has been discovered yet.
Whats the maps name? Open the console and look in the top right, it should be something like sp_a4_example.

On the developer's commentary?

I doubt you had Commentary turned on on your first playthrough. But yeah I've seen the Commentary Node up there before, it does make a picture, but it wasn't really worth looking up.

Ok, I didn't have the dev commentary on in the first playthrough but I did found that ratman's den.
