SUNK COST

Ships go missing in the Bermuda Triangle, and nobody can tell you why. You and your friends are a crew of broke sea explorers who only get to work out here thanks to a deal with the partners, a faceless outfit that runs these waters and lets you in for a fee. So every trip you take your boat out to the next ship drifting in the fog, climb aboard and drag out whatever might sell before it's too late to leave.

The ship is not on your side

Every trip brings a new layout, and no ship stays level for long. The deck keeps leaning as the trip goes on, so furniture slides across the rooms and the corridor you came in by slowly turns into a slope. Water seeps in from the lower decks and keeps climbing, and at some point you'll have to decide whether that safe is worth swimming for.

Find the most valuable items

A compass, a paperweight or the occasional golden crab will fit in your pocket, but the real money is in things nobody should be carrying, like pianos, safes and antique wardrobes. One person can drag them out alone with enough patience, and two get there much faster, as long as nobody lets go on the stairs.

Keep an eye on the piano, too. Nobody has ever seen one move, but if everyone looks away for long enough, it starts making its way back to the room where you found it.

Something lives on board

The creatures of the Triangle were here first. The ships are full of all kinds of them, and not all of them are friendly, which you usually find out at the worst possible moment.

Open water is no safer. Swim too far from the ship, the boat or the barge, and something in the water might take you.

The partners want their money

Everything you bring back goes to the barge, where the partners count it toward your quota. Their shop will sell you different gear for the same dollars you owe them, which doesn't make the number any easier. You get three trips to make it, and the partners have their own way of dealing with crews that don't.

The dead can still talk

Voice chat works by distance, so a friend two rooms away won't hear you yelling about the piano unless somebody bought a radio. The dead hear everyone but can only talk to each other, so you get to watch a piano slide toward your friend's back with no way to warn them.
