At Eternity's Hatch

About the Game

A mystery puzzle adventure set aboard a 1950s research vessel. Stranded at sea in an alternate timeline, you must utilise the ship's time-travel abilities to uncover information and solve puzzles across multiple timelines to return home. Along the way, discover secrets about the ship’s origin, its captain, and his quest to reach the Greenland Sea in search of a supernatural anomaly that threatens humanity, and learn enough to bend the forces of science and nature to your will, shaping the story’s outcome.

• Unique Time-Travel System – Switch between a looping 1955 and an ever-advancing 1992. Changing something in the past creates a new timeline and you can travel between these branching realities to use the different effects of your actions.

• Nautical Mystery – Piece together a fractured story of a scientist and former WW2 sailor obsessed with the anomaly, a mysterious weather event that created time travel, and poses a threat to humanity. Your choices in how and when to act will shape the outcome of this story, exploring themes of fate, creationism, and whether the future is something discovered or something made.

• Environmental Time-Travel Puzzles – Solve intricate, puzzles across time that require careful attention to the rules of time travel and help unravel the msyery.

• Atmospheric World – Explore a detailed, hand-crafted ship in the Greenland Sea, a research vessel converted from a 1950s fishing trawler.
