Poseidon

Greed brought you here.
Now the sea demands payment.
In Poseidon, a first-person psychological horror game, you are Captain Alex, leader of an elite 8-member salvage crew on a mission to retrieve lost pirate gold from the depths of the Indian Ocean. But what your crew hauls aboard is not treasure it's a curse.
After disturbing the wreckage of a sunken pirate ship long buried beneath ancient, silent waters, your vessel becomes a prison. Ghostly whispers echo through rusted halls. Shadows flicker where there should be none. One by one, your crewmates vanish, claimed by vengeful spirits that now stalk the Poseidon.
You are not alone.
And they are already inside.
As the last surviving soul, you must explore the haunted corridors of your once-proud ship, uncover the truth behind the cursed treasure, and solve atmospheric, story-driven puzzles to survive the nightmare that has surfaced from below.

"The gold was never meant to be found. Now, neither are you."
Wishlist Poseidon now. Set sail... if you dare.
