NightMariners

Set sail across cursed seas, recover the lost fragments, and escape before the darkness consumes you!

NightMariners is a co-op horror and exploration game that you can play solo or with friends. Choose your mission from your mothership, board your raft, and explore eerie islands, abandoned houses, and dark caves with procedurally generated layouts that change with every mission.

Collect valuable treasures, find the lost Core Fragment, and prepare to make your way back to the ship.

But the moment you pick up the fragment, everything changes.

Lights begin to flicker, darkness falls, and cursed creatures awaken. Exploration is over. Protect the player carrying the fragment, reach your raft, and escape before the island sinks beneath the waves.

Explore Together, Survive Together

Gather your crew and embark on dangerous missions together. Don't lose each other in the darkness, share valuable loot, and when things go wrong, decide who gets left behind.

A Different Adventure Every Mission

Explore abandoned houses, mysterious islands, and flooded caves with ever-changing layouts. Discover hidden treasures, open chests, and uncover secret digging spots. But remember, every extra piece of loot could make your escape more difficult.

Finding the Fragment Is Easy. Escaping Isn't.

Once you pick up the Core Fragment, the entire area begins to fall into darkness. Threats grow stronger, creatures become more aggressive, and your path back to safety becomes increasingly dangerous.

Earn, Upgrade, and Venture Further

Earn Doubloons and Crew XP by completing missions. Upgrade your raft with more powerful engines, better lighting, and new improvements. Unlock new equipment and prepare for your next expedition.

The Right Equipment Can Save Your Life

Choose from flashlights, paddles, harpoons, flare guns, medkits, and portable torches. Manage your limited equipment capacity carefully, because every item could make the difference between survival and disaster.

The Sea Is Never Safe

Face creatures lurking behind doors, deadly threats that latch onto your raft, and mysterious predators hunting beneath the waves. When darkness falls, the Night Mariners begin their hunt.

Customize Your Crew

Earn permanent Cosmetic XP, change your character's appearance, and unlock new customization options. From spectral arms and the color of your lantern's flame to your raft's appearance and lighting, create your own unique style.

In NightMariners, finding the treasure is only the beginning. The real challenge is bringing it back to the ship.
