The dungeon is a ramshackle series of buildings built from crashed and abandoned ships and planes

>The dungeon is a ramshackle series of buildings built from crashed and abandoned ships and planes

are we talking submerged or on land?

So a spacehulk?

Half and half

i wouldn't really call a costa rican village a dungeon

It could be a fun, if tedious, dungeon. Clearing out the maze of tight quarters with the added danger of water hazards and structural failure can certainly be interesting.

Not sure what to populate it with though. Small creatures with some ability to use tech would be cool, especially if they create traps/kill zones out of old parts.

Goblins or kobolds probably. It could be interesting though how traps are simply the structural integrity breaking down. Rusted floors collapsing into jagged pits of warped steel, gas leaks triggering fires, rusted doors trapping players, jagged glass on floors, etc.

Imagine a large half-submerged area that the party has to get across. If they try to swim a large rotor is turned on underneath them and causes a whirlpool.

Or a long narrow hallway with bulkhead doors on either end. Party enters one and has door locked behind them and a bilge pump starts dumping water on them.

You've clearly never been to one.

>Party barely reaches the other end of a flooding submarine hallway and go up the hatch
>It leads straight to the well-kept interior of a cruise liner
>They find a dining hall where various monsters wearing casual summer clothes are eating burgers

Party is on a ship that gets wrecked in a storm. Wake up on an island that has lots of vegetation but nothing that you could call a tree. Find village made from wrecked vessels, locals are friendly enough but adamant that they own the parties vessel now and are not allowed in the village.

Make it so party needs to recover something from their ship. Upon entering they are forced to fight the locals who have a cargo cult thing going for them. Going deeper into the structures everything is more flooded, and they eventually start to notice large eggs in some compartments.

Turns out the village has been enthralled by a large sentient sea serpent. Monster crashes ships onto island to provide building material, locals watch over eggs and help hatchlings, that feed on sailors bodies and locals when supplies are low.

Party can either try to bargain with serpent or fight it. If they destroy eggs the serpent will go into a rage. Final battle is party scampering through the structure trying to lure the monster onto the land where they can actually fight it.

>The only food is in the cargo holds of new additions
>Everyone can feel the vessel crash and shudder as the new vessel appears violently, and attaches itself to the hulk, screeching as it slowly finds its place and sets
>outside the hulk, if you can find a porthole that peers outside, instead of just into another vessel...
>Nothing but an infinite expanse, filled with wrecked vessels floating idly by, or towards, the hulk

...

Sounds like a fun concep, but a pain in the ass to map.

Maybe it could get mapped out as players go, or you can make several separate floor plans and just stick them together in order to emphasize that it's just several different ships put together.

>This is what happens to vessels that enter the Bermuda Triangle or otherwise vanish without a trace.

Bump

You called?

But, like
It's on Earth
And it's a dungeon
Or something

It could be worse
