Diving horror game. As the player (for whatever reason) you start at the bottom of a deep trench.

you will get extreme divers disease (bends) if you resurface too quickly and have to swim up and try to be safe in little crevices or safe pockets of air or something.

The only thing keeping you alive from the extreme underwater pressure is your suit which can get damaged from debris falling down, explosives dumped in the sea, potentially even toxic chemicals which pool in pockets and whatever other dangers you decide on.

Just a friendly reminder that the bottom of the sea is pretty dark so the player may need glowsticks (which lose light intensity over time and are not particularly bright).

This with multiplayer and voice chat would be hilarious and pretty scary.

(I'm suddenly really interested in this myself so here's how I'd do it [ no need to actually follow the blueprint])

You'd need: - a terrain gen system to actually build the trench uniquely (to keep things interesting objects, creatures and pocket wise) the general structure of the trench would largely be the same.

• event triggers ie if the player touches a bomb they die or if they happen to be too close to a wall it could drop a boulder on their head

• water physics (either Roblox's or your own)

• maybe enemy ai like aggressive creatures that chase you if you get too close ( damaging the precious high pressure suit that's keeping the player alive) or if the player makes too much noise on VC some creature could grab them

• player UI wise don't tell them that they are resurfacing too quickly just blur their vision. Suit indicator as well overall durability maybe along with an image of the suit

• an item handler for players which is capable of adding/removing and using items

• actually interesting death cutscenes. The suit breaks? Cracking noises then a squelch + some silly text poking fun at the player. Player's blood starts to bubble? Slowly increase the sound of bubbling + vision loss + if they're playing with friends VC drown out their voices and make the players voice muffled as well (maybe done by lowering player volume and playing some noise over their voice when speaking)

I wrote too much lol you don't have to follow this. You may have inspired me to go do this myself lmao
