1.021 - Two small hotfixes

In VR, presumed fix for spawning way up in the air or below the level on reloading a save game/level.

In non VR, fix for gamepad not receiving focus on the explorer diary menu.

We continue to have one particularly annoying VR bug where some people, apparently in particular on Windows 10 and when having the PC connected to a TV, are not able to click things in the VR main menu or inventory menu. We are still trying to figure out how and why. A work around was posted in the Steam forum for now, but if anyone suffers of this please let us know your system specs and any other information that might help us pinpoint the problem.

VR Support

July 20 - Major VR patch and update released including VR inventory and crafting. See patch notes for details.

TSP has work-in-progress support for VR (Vive/Oculus). Support for room scale and the Vive controllers! This is a high end and very large VR experience that requires a powerful computer to be played in VR, and some features still require additional polish and fixing in VR.

About This Game

A single player exploration driven adventure with survival elements, set on a mysterious and seemingly uninhabited alien planet. Survive through exploration, and unlock the mysteries of Gliese-6143-C. From the creators of "Unmechanical" and successor to "The Ball".

Earth has been destroyed and mankind lingers on in a small fleet of ships near Pluto. As humanity's last hope, you are sent to scout a distant planet as a potential location for a colony. After years of space travel disaster strikes however, and your ship is destroyed when approaching the planet...

With your team members dead and your equipment gone you have no way of communicating or receiving help from anyone... you are completely and utterly alone...

Desperately you look for a way of phoning home, but as you explore the seemingly desolate planet, you uncover the dark secrets buried within the depths. In this otherworldly odyssey you uncover mystery upon mystery as you try to survive the harsh climate.


  • Explore - Unlock the depths of the uncharted planet, and discover the secrets buried deep below. Delve into huge cave systems and tombs and uncover over 200 secrets.
  • Handcrafted - 10 large entirely handcrafted levels to explore. Explore and puzzle your way through 5 islands and 5 large tombs/caves.
  • Atmosphere - Atmosphere rich environment that is fully dynamic. An alien day and night cycle and a dynamic weather system that calculates everything from temperature, wind, humidity, cloud coverage impact on the climate and so on. It handles ocean tides. Plants respond to the climate. Storms form. Earthquakes happen.
  • Survive - Survive the extreme climate, tornadoes, storms, meteors, lightning, and not least the dark secrets buried beneath the surface.
  • VR - Supports Vive and Oculus, including room space and motion controllers. Explore the huge world start to end in VR! (*Some VR features are still in development - see notes at the bottom for info)

  • Depth - Plants grow and rot. Ocean tide based on the moon. Your body responds to everything from getting wet to lack of sleep to walking uphill to the humidity. Hundreds of upgrades to be found. Secret areas within secret areas within secret areas.
  • Savior - Your death means the end of mankind. Save us and rebuild a communication device to phone home, by scavenging useful items.
  • Adventure - Be a pioneer, an archaeologist, and an astronaut to explore a mysterious alien planet. The adventure has a beginning and an end, but it is a harsh world. A mistake will cost you your life.

  • Linear - The game has a start and end. It is a singleplayer adventure with 10 large levels.
  • Your Time- Scale the game as you wish. Go from a super hardcore experience to a relaxing stroll on an alien planet. In fact you can cheat old school console style even. It is your time, your experience.
  • Just You - Little hand holding. No obvious enemies. It is just you. All alone by yourself.
  • Old school - Fond memories of games from 10, 20 years ago? So do we. Complex level layouts. Dozens of secret areas. Keys to unlock doors. Underground environments. A ~ key to open the game console.
  • Exploration - There are hundreds and hundreds of things to find hidden away in the world. Secret areas the size of modern "next gen levels". Just how deep does the rabbit hole go?
  • Puzzles - Puzzle your way through environmental puzzles left by an alien civilization, like our titles Unmechanical and The Ball.

  • World - Gliese-6143-C is a harsh and barren planet, covered by a vast ocean. Days are over 45C/113F, and nights under -30C/F.
  • Archipelago - 5 islands, with a shallow sea between them and connected through a system of caves. To travel from one island to the next you must traverse these dark caverns.
  • Wreckage - The spaceship in which you arrived crashed on arrival, and its debris is scattered across the world. Find and locate debris sites to find additional resources.
  • Tombs - Megalithic tombs are all over. Clearly you were not the first intelligent being to have set foot on this planet. Who was here before? Where did they go? What happened?

  • Vive/Oculus - Works on both. Supports Xbox controller on Oculus, and either the Xbox controller or motion controllers on Vive. Supports room scale for Vive. Keyboard and mouse is supported as well.
  • Movement - Supports regular locomotion walking and teleporting. For rotating you can pick between room scale rotation, snapped rotation (45 degree steps), smooth rotation, or enable strafing. Movement speed can also be scaled freely.
  • High end and huge - This is not a small VR demo or game. It is a massive 16 hour experiences with miles and miles worth of world to explore, and provided you have a powerful machine (980 and up) you can experience it with some of the most ambitious high end graphics tried in VR to date.

TSP is not a pure VR game. It was designed for non-VR gameplay and thus a VR headset is in no way required to play the game. If you do have one, it is an awesome (but different) experience!

VR is work in progress - Currently not implemented: VR Loading screens and Oculus Touch. Some existing features such as swimming require some additional polish and improvements but are usable. Everything else works solidly. TSP received a major VR patch July 20 adding VR inventory and crafting among many other fixes.

WHAT I LOVE: The feeling of being stranded and finding a way to home. But even more, the story that unravels as you explore. Most is told through diary notes strewn about the area. Others come in a more alien form. And somehow there's suspense despite the lack of any real physical threat throughout what I've played of the game so far.

WHAT I LIKE: This is my first "real" PC game that would test my mediocre rig I built. Graphically, it looks great. The weather effects are particularly mesmerizing, as is the starlit sky at night with the moons orbiting the planets.

WHAT I DISLIKE: While the exploration is fun, it comes at a price. It can be quite frustrating to search and find, reach the final destination, and then realize you don't have all the "keys" to progress further. This requires going back and searching some more. It fits the theme of the game but that doesn't mean I have to like it.

WHAT I HATE: I'm not a fan of survival or crafting games. The crafting element is at least simplified to my liking. But the survival aspect isn't. I'm playing through on Normal difficulty with no added perks from the beginning. Nothing's worse than having to stop your progression through an area or story element so you can recuperate from cold, heat exhaustion, hunger, thirst or more. Sure, it adds to the suspense element, but I get a degree of anxiety when it happens. And it's of a nature I don't enjoy at all. (Truth be told, over the course of playing and becoming familiar with this way of playing, I prep better for survival before progressing through certain areas.)

After completing this game I am left with a feeling of having endurer.
It was grind, the Forward Vector guidance was about as useful as the wife with map reading, without the arguments just vague 3 dimensional directions as to the end point in relation to current position, except when it decided to disappear. I felt I spent most of my time not knowing where I supposed to going or what I was susposed to be doing when/if if got there. The game didn't flow or lead you through a stor, it happened around you and you got snippets.

There is a good game in ther but it fails to deliver by simply presenting too many WTF am I supposed to be doing now moments. However if you are prepared to live with the vagaries it has some good stuff in there.

Holy sh** this game is captivating. All the negative reviews are from VR kids who don't like the VR implementation. If you don't care about VR, then there is no reason not to buy this. Absolutely worth the full $20.

It's a survival game, but there are more things to be mindful of than in most survival games. Ways you can fail to survive include:
--Exhaustion (lack of sleep)
--Physical damage to body (falling, etc)

The game makes all of these even more challening by putting you on a planet with volatile temperature and weather conditions. One minute the temperature is below freezing so you have to huddle in a cave throwing stick on a fire while waiting for the cold front to pass, then the next minute it's blistering hot so that you have to run from shade to shade to keep your body temp from rising to high. And of course you have to stay on top of food and water.

Unlike other survival games, there is no farming---only gathering. And there is technically no storage, although you can still hoarde piles of things because the game will remember where you dropped them.

Also unlike other survival games, there is a narrative and an overarching goal to this game. It's not just a game of seeing how long you can survive---you're also trying to scavenge materials form crash sites to build a satellite uplink. There are also huge caves and dungeons to explore (be sure to bring food, water, and light!)---not to mention loads of secret items as exploration rewards.

If you like survival gameplay but also like exploring and having a definite end goal, then this game is worth every cent.

I emphasize again that this review pertains to the regular, non-VR experience.

7) A classic, essential, and/or must-buy game that is worth full price.
6) A good game that is worth the full price.
5) A pretty good game worth checking out--especially if discounted.
4) A fairly good game, but I'd recommend buying it discounted.
3) Not great, but a few redeeming qualities. Only buy if heavily discounted.
2) Only worth checking out if you are dangerously curious.
1) Avoid at all costs.

The VR version of the game is poor in its current state, items will fly around you whenever they touch a wall, aiming is very finicky with the teleportation device, having to look around to move can really strain your neck after awhile (Yes there is another way to move but I found that one very boring to play with). The game also makes text very hard to read in some parts, even having them completely out of your view so by the time you notice them they fade before you can read them. The inventory will sometimes disappear completely from one, or both of your eyes if you aren't looking in the exact right spot.

Currently I don't recommend anyone looking for the VR pick this up until it is updated, when some of those issues are fixed, it may be worth looking into.

This is a nice survival based adventure. You get dropped on an alien planet and you have to gather pieces to build a radio while figuring out what is going on and what happend to your ship. More you have to keep track of your environment so that you don't run out of food or water.

I've played it all in VR and it's pretty good. Tracking and movmenet works just fine and makes you feel there.
The only problems I've encoutered are:
- stairs (you have to point to the horizontal part of the steps which if horrible when you want to go up).
- Interactions. You just point at two objects and pull the trigger to get them to interact. It would be more imersive if you would have to get them to touch.
- Getting lost in caves, but I guess that's intended.

Overall is a good VR game, and I hope the developers fix the last missing bits.

I didn't know what to expect from this game... Bought it during a steam sale and hoped for the best and my god, was this the prize in all the bundles. This game was amazing and the story just pulled me right in. 10/10 would definitely suggest it.

Product received for free
The Solus Project is a first person sci-fi survival exploration adventure, that’s a spiritual successor to The Ball.

See written review below or watch it here:

Now that the Earth has been destroyed, you are sent to an unexplored planet to investigate the surface, and see if it’s fit for humans. You are the last member of your crew, and the last hope for humanity’s survival. You must find a way to repair the communication tower and report back to what's left of humanity.

  • intriguing story that gets even more interesting as you continue to explore the planet, and learn the truth (and even though there isn't any replay value as far as the main story goes, there are so many secrets to discover for those who love exploring)
  • excellent graphics; everything from the planet’s surface and caves to the sky, storms, stars and nearby planets look absolutely fantastic
  • the voice acting is done very well, and it helps to convey the importance of the mission at hand
  • the music, sound effects, and ambience work extremely well to create an atmospheric environment
  • very immersive world throughout (I was sometimes be so focused in what's ahead, that I would walk into traps, and scare myself)
  • exploration is satisfying - there are tons of secrets to find, and every one of them rewards you with a small permanent stat or resistance buff - it’s also nice that the game tells you how many secrets are left in an area when you’re about to leave it
  • there’s a lot of lore to be discovered as well, and those who learn more will have a better understanding of the story, and likely get the most enjoyment out of it
  • the survival aspects are manageable for the most part, and you are able to find enough food and water without much trouble; maintaining your body temperature to avoid hypothermia and heat stroke was a bit more challenging, and it often gives you a sense of urgency while exploring, but doesn't usually feel overwhelming
  • the teleport movement, and room-scaling is implemented well for the HTC Vive

  • when it was dark, being in extremely hot and cold areas was annoying at times because the hot and cold orbs don't give off much light, and you'll have to change between items to see where you're going (you can hotkey some of the items you use regularly, but the heat orb is not one of them - some of the items with hotkeys available feel unnecessary, and I would have rather had the option of which items to assign keys to)
  • inventory management gets tedious since space is fairly limited, and it’s not always clear what items you should keep (it might have been less annoying if you could keep walking while accessing the inventory)
  • some people will be too sensitive to motion sickness to really enjoy the VR experience because there are many times where the camera shakes from earthquake or meteors (I used PC instead)
  • I encountered an issue that caused me to be unable to finish the game* without completely starting over (partially my fault, but the game should have stopped me - a completely separate auto save point right before you pass the point of no return would have saved me)

*I ran into an issue where I unknowingly skipped getting an orb that makes you cold, and continued playing the game not realizing. I then got into the final chapters of the game, and hit the point of no return. I was warned to be prepared, so I was stocked up on food and water, and figured I was good to go. However, I did not have this one specific item that keeps you from dying to heat stroke in intense heat; this item seemed to be required to finish the chapter, and I have no idea why the game allowed me to skip getting it in the first place. I admit that I am partially at fault for not having fully explored. After hitting this point of no return, I couldn’t find any way to go back, and I couldn’t finish the game without restarting completely.

I played The Solus Project for 11 hours, but over an hour and a half of that was me being stuck trying to get through a part that was actually impossible for me. I was close to the end, and I never intended to go back and try to find more secrets, so despite my issue with not being able to finish the last part of the game, I still really enjoyed the game overall. I’m just glad that I was able to watch the ending, otherwise I would have been really mad. I'm sure there aren't many people who have come across a problem like this, but I still hope they fix this issue though, so that this can’t happen to others. It’s still a really good survival exploration game, with a lot of secrets to uncover, and I enjoyed playing almost all of it.

I have played this on HTC Vive with a 980ti as graphics card.

I think the game is incredibly good, I can't recommend it enough for playing in VR. Probably the best VR game that exists at this time. It is very immersive, great atmosphere, has good graphics, cool visual effects, an interesting plot. Once you get into it, it is difficult to stop playing. I havent had as much fun with a game in years. It is like playing the main character in a great scifi movie.

Besides being a good game it is also quite cheap, well worth the money!

I have nowhere nearly finished the game nor did i explore any of the "secret" caves yet but after 12 hours i can say i absolutely adore this game.

Let's get one thing out of the way, the survival mechanics are generous, just watch when to eat or drink and watch your temperature and sleep.
The survival mechanics aren't that difficult (i play at 200% difficulty).

Forget guns or action packed gameplay.

Why do i like this game then ?

* Exploration
* Lore
* Fantastic visual design
* Atmosphere
* Sound
* ...

This game made me feel alone on a hostile yet beautifull world.
I wanted to know what happened, where i was.

Seriously, try it. NOW ! ;)

Easily one of the best single player games I've played in years. The game keeps you on edge, as soon as you begin to feel comfortable it throws something new at you as you struggle to balance your body temperature, food and hydration levels, and exhaustion.

Well worth the price tag within the first hour alone, and I would highly recommend it to anyone I know.

With 71 VR games in my steam library, this is by far my favourite, most polished and complete experience. This is a prime example of what VR should be like - a full lenght game instead of just another tech demo.

As for the adaptation to the VIVE, I actually found the walking locomotion using the VIVE controller trackpad to be far more immersive than teleportation. I don't think teleportation does this game any justice. I personally didn't get any nausia and wish more games utilised trackpad walking.

If you belong to movie fans Mission to Mars, The Martian, or Interstellar, then this game will for you.

Before play first act, we got simple introduction. Earth is on the verge of ecological destruction. Desperate humanity begins search for new worlds to colonize, and we play as a member of one those responsible for this mission teams of explorers. The aim of the research expedition was reach to the planet, made establish base there, exploration planet to the research and preparation for the next expansion of the settlers. After twenty years of travel stellar, research expedition of The Solus 3 arrive at the place, but the landing on the planet ends in an accident, of which the result killed the entire crew! (of course except of character player) Worse, the damage is most of the hardware, including communications equipment. Thus, we are completely alone, and we can count only on themselves! Just you and mystery planet!

The Solus Project is based on survival. The game included simplified mechanics of crafting with logical elements as also the discovery of secrets, hidden by the world and equipment recovered in the course of the story. Player need sleep, must maintain proper body temperature or the level of food and hydration. Must avoid injuries resulting from the fall or confrontation with hostile flora and fauna. You can die by starvation, hypothermia, overheating, drowning, hurricane, lightning storm or even meteor shower!

Visually, we get unreal engine 4 with excellent sound effect and music, by what the game encourages you to explore all parts of the world, filled with the many secrets waiting to be discovered. Each sector is filled with monumental ancients structures, which can visit on your own or as a result of the progress of the story. Realy nice to see. Pleasant atmosphere with a touch of fantasy.

I had good fun and I recommend try it!

9/10 - requires patience and determination to finish each act. There is a lot of walking and long distance from point to point and sometimes after long walking (special in caves) it becomes plunge.

For starters, I haven't had the chance to try this game on VR, so my review is with non-VR play in mind.

I really enjoyed this game, through-and-through. First of all, the art of the planetscape, with all its unique flora especially, was spectacular. While at first I doubted that the survival and story elements would cooperate, I was quickly surprised by how well they worked together to form and immersive experience. The game is really engaging; I really felt like it was me stranded on this strange planet, seeing so many strange things, trying to understand what was going on. There wasn't a dull moment in this game, from start to finish, but it didn't feel stressful either, like some survival games. All in all, a great experience that I intend to play again. Would also love to try this game out on VR - after playing it normally I think it would significantly enhance an experience I already really enjoyed.

Really the only thing I can think of about this game that bothered me was that your PDA is called "Wilson" but has a female voice. That's literally the only thing that bothered me. Everything else leads me to recommend this game :)

Really fun game to play. The crafting/item use I think could use some adjusting (I'd like to have to do something and not just point and click. With the VIVE the intro as well as the menu screen are freaking unreal. If I'm not sitting then I dam sure am standing as if i was riding a snowboard or something just to keep from falling. I swear that main menu is going to give me a heart attack.

Two words, Simply Amazing. Yes, there may not be much combat but I'm am 100% fine with it when there is such amazing exploration in the game with many hidden secrets where I have only found a few. It's a trie exploration game. I had this game in my library after buying it in June and playing it only for an hour and ten minutes, but I started to play again and I didn't regret it. I finished the story and II won't reveal anything, but there was this one part where it was very similar to the movie Prometheus (which you should watch). Its so similar to the movie and it made me understand more. Honestly, the texts and such on the wall, I didn't really pay attention to much. But, I always would try and hover over them to get them into my explorer diary so if I wanted, I could read it later. I don't remember where I saw this game, but I quickly knew that I had to get it. Amazing game, the story could've been better, and very well done by the creators for the effort they put into this game. 10/10 would play again.

This is my first "real" game for the Vive. While I find the game lacking in things to do, it looks great and I enjoy just walking around taking in the views. I'm not too far into the game due to lack of time, but I'm looking forward to finally digging into it and completing it.
