At Eternity's Hatch is a mystery puzzle adventure for PC 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, solve puzzles across multiple timelines and alter the past to return home. With puzzles tied to narrative, you will discover secrets about the ship’s origin, its enigmatic captain, and his quest that has led him to the Greenland Sea, in the hope that you will eventually understand enough to control the forces of science and nature at your whim, playing your part to determine the outcome of the story.
The game will be available on PC and is designed for fans of narrative-driven, atmospheric puzzle games, such as Outer Wilds and Return of the Obra Dinn, who are motivated by curiosity, love uncovering layered mysteries, and appreciate games that reward observation and thoughtful problem-solving.
Features

Unique Time Travel System
Our time travel system forms the backbone of both At Eternity’s Hatch’s puzzles and its narrative. Shift between two different time periods on the ship, the present constantly advancing and the past stuck in a loop, and hop between timelines. Think critically about the rules and consequences of time travel, and use them to shape the world around you.
1950s Research Vessel
The Tempest, a repurposed fishing trawler and research vessel chasing a mysterious anomaly in the Greenland Sea. Explore deeper and deeper through the vessel both newly built in 1955 and dilapidated in 1992.


A Captain and
his quest through time
Uncover the story of Cornelis Schuitemaker, a scientist and former WW2 sailor obesssed 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.
