Dive into a dark mystery under the waves in this moody detective adventure. It all starts when the captain of a one-of-a-kind submarine turns up dead—under circumstances that just don’t add up.
The Mortuga Submarine sits hidden near a crumbling fishing town, and inside, secrets pile up: old legends, odd crew members, and enough strange happenings to keep you guessing. You’ll play as Detective Grimoire, working alongside your partner Sally, both of you drawn into a locked-room murder that teeters between hard reality and the unbelievable.
Every clue matters, and nothing is off-limits. You’ll get hands-on with each piece of evidence, twisting and turning fully interactive 3D objects to spot what others missed. Dive into tiny details, connect the dots, and don’t take anything at face value—was the captain another victim of the sea’s old curse, did someone on board commit murder, or is there something even stranger going on beneath the surface?
As you roam the Mortuga’s hand-painted halls, no two rooms are alike. Puzzles pop up where you least expect them, the crew’s a curious bunch, and you never know what might be hidden around the next corner. Full voice acting breathes life into every suspect and witness, making each conversation just as revealing as any physical evidence.
With the Budapest Art Orchestra weaving an intense, haunting score throughout the game, the atmosphere drips with suspense. Piecing together clues, interrogating suspects, exploring every nook, and unwrapping a supernatural mystery—it all comes together into a story you won’t want to put down. Every discovery brings you closer to the truth, and trust me, it’s one that’ll leave you reeling.
