Tidebound

The colony ship Horizon’s Wake was never meant to drown. Stranded on an alien ocean world, humanity survives in the shadow of broken steel and rising tides, deploying pressure-rated mecha to fend off towering biomechanical warforms rising from the deep. The enemy are called Nereids—luminous, sharp-toothed sea-women who pilot living crustacean machines and fight with ruthless precision. But when you spare one of them on a blood-soaked shoreline, and she bites you in her panic something changes. Shot down at sea and left for dead, you awaken on drifting wreckage—rescued by the very Deep-Maiden you once carried back to the water. As war brews between your people and her conquerors, the tyrannical Selachai Dominion, survival becomes something more complicated than victory. Because her bite did more than draw blood. Now the ocean is changing you. Amid crushing depths, forbidden alliances, and mecha battles beneath alien moons, a fragile bond begins to form—one that could ignite rebellion… or drown both your worlds. The tide has chosen. - Loosely inspired by elements from both Subnautica and the anime "Blue Submarine No. 6" - Includes @LewdLeah's Inner Self script! - Yes, I really really want to shoot my shot at March's monthly carousel.
