Lacuna Passage by Random Seed Games is a survival game where players take on the role of Jessica Rainer, the last surviving astronaut of the second manned mission to Mars. Originally slated to support the first team with additional supplies and equipment, her mission was changed to a rescue operation after contact was lost with the advance team. Players can explore a 25-square mile area of the red planet in a sandbox survival mode or a narrative-driven Story mode. Players will unravel the mystery of the fate of Jessica's fellow astronauts, all while trying to stay alive in the harsh and unforgiving Martian landscape.
