I’ve found the terminal, linked up and discovered the truth of Oceanus Prime (reminds me of Airlock!).
But, I’m a little stuck now. I need to deal with an indentation and I have a glass tube. I don’t know what to do with either one.
Things I’ve tried:
-Putting the glass tube in the indentation
-Pushing the indentation
-Putting the gadget in the indentation
-Entering the fast water tube that kills you
