Lacuna Passage is a story-driven exploration and survival game set on Mars, drawing inspiration from titles like Dear Esther, Gone Home, and even Pokemon Snap. You play as Jessica Rainer, the only survivor of the crashed Heracles mission, investigating the disappearance of the first ever manned mission to Mars. You have several tools at your disposal, but most important are your skills of observation. You will need to uncover mission logs, recorded audio files, and other physical clues left behind at critical mission locations in order to uncover the story. An interplanetary trail of breadcrumbs is waiting for you.

There are 25 square miles of open terrain around the crash site for you to explore, and in order to find the missing crew of the Hermes you won't want to explore blindly. You must carefully manage your vital resources or you will find yourself stranded in the great red wasteland with no food, water, or oxygen. Will you simply survive and wait for rescue, or will you risk your own life to find the truth? Time and nature are your enemies in Lacuna Passage.


  • Terrain generated from actual Mars satellite data.
  • Survival mechanics based on real metrics like blood glucose, heart rate, caloric intake, and more.
  • In-game photography that allows you to capture any moment and document your discoveries.
  • An immersive HUD that is accurate to potential future space exploration physical display technologies.
  • A hauntingly beautiful dynamic soundtrack that responds to your actions.
  • A mysterious single-player story that encourages non-linear play.

Amazing! Keep it as realistic as possible and unforgiving, above all. Also, why not make more game modes? Perhaps, pioneering a colony? As well as, spectator mode, to watch AI manage their resources and complete (or fail) tasks without your intervention?

Good luck!

We had a chance to see the visuals of this game in person, move around in the environment, and see how it looks on our PC. I've talked to a couple of the developers and we are looking forward to this game over at fragsandbeer.com. Shaping up to be a fantastic survival sim.
