I know this is way early, but....

What do people hope to find in the Underwater expansion for Sunless Sea?[li]
I’m hoping it’ll integrate with the current game, and that you launch your Zubmarine from the boat, and have to return to it…
Do you think it’s going to come with more content? (Islands, etc.?)

Sunken ships and drownies. And Other Things.

At least one reference to some Lovecraft short story that I can’t even remember the name of.

A drowned city :3

The Temple?

I think so actually, thanks.
That short story would make for a cool game over scenario, where its possible to find the remains in the next round.
