Explore a massive terrain generated from actual Mars satellite imagery. With features generated from scans collected by the HiRISE project and details painstakingly designed to reflect the photography captured by planetary rovers, this is as close as you can get to visiting the true Red Planet.

Survive the harsh Martian environment with mechanics based on real health metrics like blood glucose levels, heart rate, caloric intake, and more. You will feel like a true interplanetary pioneer as you conquer the elements and survive randomized threats like dust storms.

Capture the beauty of Mars with an in-game photography mechanic that allows you to document your discoveries. Photos are saved to your computer at full 1920x1080 resolution and can be referenced in-game where you can set objective points to navigate back to where the photos were taken.

Interact with the various astronaut technologies through your dependable datapad. You will need to manage inventories, salvage and craft supplies, and repair vital life support systems in order to survive the desolate landscapes of Mars.

Early Access Review Hello Friends of the neat survival game fun! Today I give a Review on the Title "La ... Mööööööap. I am no longer willing to continue writing. My Powers are letting up. Family Problems ... Three Puppies adopted, a Child produced, Grandma and Grandpa deceased, tja life is not a Cake. Oh my god. The Review writer simply cancelled Sails in the middle of the Review!!! Nightmare! Neeeeeinnn .. Well People, further down the Text I'll let You release some empty Text Boxes, you can enter yourself after the Purchase as You find the Game. Ok, Fun own. The Developer has actually announced today that the Game will remain in the EA until further notice and he will only be Bugfixing. Wants to be: ER MACHT THE ABFLUG!!! At the End of his unspeakably long-winded Text, he thought that perhaps, maybe not, or maybe it might, but certainly not the same, he would want to move on at some point. Mmmh. Hey Tyler Owen, is this really yours serious?! You're home? Leave us all alone without even wasting Any Thought that we have all relied on Your Programming skills??? in any case. My Revenge will be bitter! I'm going to give You a NEGATIVES review. Will interest the Guy zero, but I've shown it now. You at Steam Should start by thinking carefully about how many Customers you want to greuse with such bottle programmers! Dear People, the Game started really well-honestly-but what is happening now is real the Last! FINGER WAY! The Game is no longer developed and is therefore a binary Break Bude! Anyone who has made a positive Review a game should quickly convert it into a negative one! I hope I could warn You forcefully enough! Thank you and Eyes on when Buying a game! Your Survivalstevie!

Early Access Review A very atmospheric survival game with simulation touch, Graphics and very captivating. When I saw the Game the First time, I had to load it on my Wish List because the Name already sounded so epic but of course also because of the "survival on Mars" aspect. It is still in the Early access state but already has great playful Value. Until now, there is "only" the Sandbox, in which you simply have to find and reactivate three Habitats and repair them beforehand. This means that you should bring the right Spare Parts or the Parts for a Blueprint that you can craft in a Habitat if you have found the Blueprint to do so. I've played the Survival fashion 3 times now and found different blueprints in the sessions. So if you are Unlucky you can not find a blueprint in a gameplay, for example, for the heater-parts which are very important. I don't know if this was thought of by the developer or just too early but is therefore replayable the Game and also because everything on the map always spawn in other Places. On the Way through the Marsterrain you will find Boxes with valuable Cources such as Food or Components for Habitats or practical Items such as a portables solar panel so that you can charge your Battery which is important for The approach heating And the Scanner and the Lighting because at night is absolutely dark at Mars there only the Stars glow. Oxygen tents for resting and supplying Are also on the way and the Navigation points can be found in the Form of Transmission towers, which must also be activated, repaired if necessary and Used Backups. A portable Oxygen tent can also be crafted. In addition to a Variety of Food, you also have to carry Water and off and then consume or anti Wheel pills against the Radiation And a few Oxygen Cylinders anyway. A vital values screen allows you to see how exhausted you are or what Food you should eat, etc. For the fact that this Game is unfinished I think it is already great on the story mode that the Developers are working on and the map is also big enough for survival fashion. A very atmospheric and exciting Experience that I don't want to miss. Lacuna Passage is highly recommended!!! Update: Meanwhile you can drive around with nem Martian Buggy with proper Storage Space and in the 3 Habitats you can now analyze rock and Air Samples, which of course you have to collect in the Field.
