As always, I’m going in as spoiler-free as possible. I’m not even telling you where this floodgate is in Resident Evil Village, or what you’re doing with it!
Also note that the puzzle image below is how it looks when you walk in the room. The solution is embedded in a link. And the header image isn’t even related/in the same area!
