Where do I go from here?

I have been stuck in subterranean for a while now, and I need an extra cycle to get through this gate. I see echo particals in the area, but can't find the echo, and therefore can't get another cycle to get through the gate. Any ideas?

you can always just keep that gate in mind and come back to it later on it does look quite different

what echo particles have you been seeing, though?

I saw yellow partials just above the gate...

If I don't go through the gate, where do I go? Should I go to the filtration system?

you can go anywhere you would like!

Okay! I'm just wondering how to finish the campaign.
