Just Found out, Scuba Diving is a rabbit hole!!!

Snorkelling doesn't look like a rabbit hole, though, and there are reefs to snorkel at. I'm assuming that'll work with first-person mode too :) I can live with a deep-see diving rabbithole if I can first-person snorkel at a reef.

So I went to the source and found this:

"So, there is no active diving except snorkeling. I didn’t see how it works."

Based on that, I think there will be diving in form of snorkeling , but if you want to scuba diving, complete with the gear, you can only do that through buoy, which is a rabbit hole.
