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.

The Solus Project is a game that is not perfect, but works well with what it is. Focused on basic survival around drinking water, managing heat/cold, and fighting hunger wrapped up in a linear narrative, this game is focused on a combination of seeking secrets while managing one's own failing condition. The game's narrative itself is the focus of the game, don't expect crafting to hold your interest. It's pretty basic at best and mostly used to limit your access to certain items. There's a reason why a lot of fear in the game comes from losing your torch. Though I'll say that it will be nothing compared to that one small section.

I will say the ending is kind of weak, felt kind of like they weren't sure how to advance the story more. Otherwise, enjoyed almost every moment of this game.

The best experience I have had in VR so far, this game has taken me to places no other VR game has so far. Some may find it slow but I enjoy that in a single player game. It's mainly about survival and gives you missions to complete to help you survive. There are little bits of story all around you to discover and if you take your time it builds up a great back story.

This game has sold me completely on VR and what In depth games can be when some longer and more story driven games are released for VR.

Some of the stunning VR moments for me have been.

Watching meteorites crash all around me
Shining a light into the water and seeing depth to it like never before
Exploring deep within caves and looking up to see the the high cavern ceilings with my torch light flickering of it
Going under the ocean and feeling like I'm under the ocean.
Watching the massive moons move across the sky.
Standing in a torrential down pour and almost feeling it hitting me.

I know pretty mundane stuff but it all adds up to making the game more realistic than anything else I have played up to now. Just the fact that when I'm playing I really feel like I'm on a distant planet.

Anyway if you have VR and enjoy story driven survival games on distant planets then def give this a go.
Also if you have a large fan make sure you have it going on you when you're playing as it really adds to the immersion.

HTC Vive Review * after 2 hours play

A menu that wouldn't let me select anything at first (needed to alt tab on my PC), an hour of figuring out the controls, settings and movements, clunky Vive controls ...

None of these things detracted from this being my favourite VR experience yet!

This game works best once you've got used to artifical locomotion (I used to get really really sick, now not at all). It has a teleport system in it, but it's not quite as smooth as the Lab, and I personally find teleport breaks the immersion.

Last night, I crash landed on an alien planet, where there was lushous grass and rock pillars and I was really there, warming my frozen hands on the engine of my broken rocket, watching shooting stars fly past the moons in the sky. Searching around for food, I sat down to eat, and watched as light slowly creeped into the alien world as a new day broke. I survived my first day!

This all felt very very real.

This is clearly a beta VR experience, but the world fits VR so well that it's clunkiness can almost be ignored. How this is so far down the VR recommend list is a mystery to me... But I can advise anyone wanting to play this to go and try some demos with artifical motion first, and see if you can get used to it. Took me at least a few weeks, maybe even a month. If you can though, it is well worth it for this experience alone! Worth the full price I paid for the game.

Would pay €40 no probs for a game like this if the VR was just a little bit better implemented.

A review with the HTC Vive. I just started it and I already enjoy it immensely. It's an immersive and beautiful environment. It's heavily a survival based game so it keeps you busy and moving around. The visual appeal of the game alone is worth checking it out, but it also feels like a fully developed game. Most games available for VR right now are like tech demos, so this is definitely a nice change of pace. Recommended!

FINALLY a game worth playing in VR! If you have the VIVE get this game! I am so sick of games for VR being extended tech demos. This is the real deal, when the rain starts up and then a tornado hits in VR its EPIC!!!! Very scary and enjoyable. This is the first review I have ever written and I have been with steam since HL2 was the new hotness. in short I LOVE this game in VR. I can't wait for more fleshed out games, the tech is there the games are not.... This is a glimpse of the future God Bless You Guys and keep up the good work!!!!

Excellent game, one of my new favorites for exploration/puzzles in first person. The storyline moves really well, the graphics and textures are on point. The first ten minutes can be a little daunting as you understand how to combine items and how the game's flow is going to be but after that it carries onward. If you aren't interested in storylines you might not find this as good just from a puzzle perspective. There's no combat at any point, either. It plays a little like Amnesia but somehow feels like Portal 2 in terms of the atmosphere. I haven't found nearly all the locations and "secrets" that are in the game yet, as I was driven to complete it and understand the full story. The story itself is something unique and interesting, not much can be said about it without giving too much away though.

The controls all made sense and managing health/thirst/hunger/sleep seems daunting at first but is manageable once you realize where the game is going to put resources for you. The only bug I encountered was with the inventory. Sometimes the inventory would disappear when you move your mouse and you'd have to do this multiple times before you could actually switch items. You can use the keyboard to do this too, but in some situations time was of the essence.

The only negative part of the game is the male protagonist's voice acting. It's just terrible all-around. The quality of the voice isn't the issue as much as his acting, which is disjointed and awkward sounding. The character speaks probably less than ten times throughout the game, giving short audio diaries to send home that you listen to, but each time given the circumstances he's in at the moment his attitude and demeanor is entirely inappropriate which draws from the immersion of the game. I'd say his acting is on par with a high school theater student. Even without a change to the script, replacing his lines with a more capable voice actor would carry the game a lot further in the long run. I'm not sure how the female voice is, but I will try that option for my next playthrough.

I'm part way through this playing in VR with my Vive. The controls are a bit clunky but once you've got the hang of it, the game is simply wonderful. It's perfectly paced, challenging, unsettling and fun. The alien world is beautifully realised and genuinely convincing. VR adds a lot to this - you feel like you're really there which is both brilliant and slightly disconcerting.

It takes a while to get going and the first half hour is a bit confusing but it's completely worth the effort to get started.

I don't know how good the game is without VR, but anyone with a Vive and a bit of patience really has to get this. It's head and shoulders above all the mini games and other stuff around at the moment. It's also a huge game with massive vistas and a great sense of scale and exploration

This is by far the best game I have played so far on the HTC Vive. So polished and engrossing. I found it hard to put down. The story line is superb and very well written. True escapism. Worth every penny.

This game is amazing. Just. Amazing. The next level atmosphere, the incredible story. Uncovering the history of this species just gave me thrills. It's a generaly long game, but I never felt like I was slaving away trying to do some sort of useless puzzle. No. In this game you are always doing something productive. It's like you can never get bored because every area is different. In short, I loved this game.
The only complaint I had was the ending. I feel like the game could've even gone on a little while longer. The ending was very short. I just felt like it didn't fit with the rest of the game. But otherwise I loved it. I have never felt so involved in a game.
10/10 worth every penny!

If you're a millenial this is probably awesome. If you love VR this is probably awesome. If you're like me, old and tired, it sucks. Great marketing once again. NMS got shot down for being different and innovative and yet, ten minutes into this game and I'm dungeon crawling. All those gorgeous vistas and orbiting planets (very present in NMS) are replaced by cavern walls and Tomb Raider doors (without the fear of a horrible spikey death which might have added something)

Not my cup of Darjeeeling I'm afraid. Very over-rated. Gotta have my 2 cents heard here, not that my opinion matters, but seriously, it aint that good. No wonder developers don't release demos anymore. Sorry, Devs, wanna support ya, but I just can't on this one. (Note to self: Paly, stop reviewing games you don't care about after a hard day and two beers)

This is my absolute favourite of the year! And I'm not that into games in this genre! The game grabbed hold of me from the first moment and kept on grabbing. The beautiful scenery, the music, the mystery you at first don't even know exists, and of course the goal you have. At first it presents itself as "just" a very pretty exploration game, but hour after hour it pulls you forward wanting to find out what's going on. In the end, you are knee deep in a story that you just can't wait to unravel. In that sense, it is an exploration game twice over!

Oh, and the sounds! You're not human if you're not affected by them! Not going into detail. It's up to you to experience. Just grab the game already!

Un survival game che puoi giocare senza elementi survival, in un open world con una trama da seguire, The Solus Project è un gioco interessante, impreziosita da dettagli curati e dal tornado più spaventoso mi sia mai capitato in un gioco. Da vedere.

Wow. This game provides a bit more of what I had hoped "No Man's Sky" would provide. Some real unique alien planetary exploration. For some reason, I thought this game was considered a sequal to "The Ball", but you won't miss anything if you don't play "The Ball" and it's really a completely different type of a game. "The Ball" being a entirely ball based purely puzzle game, and "The Solus Project" much more of an epic adventure survival game.

"The Solus Project" comes with three difficulty levels. "Casual" - more for explorers that want to experience the story, but don't want to micromanage for survival. "Normal" - this is what I'm playing. You have to survive in adverse conditions, things like heat, cold, food, water and wetness all affect your heatlh. You also have a visual hud that guides you through your most inportant taskes. And "Hardcore" which is like "Normal" but you don't get hud icons and hints for what to do next. I have seen it mentioned on the forums that real survival enthusiests tend to think "Normal" is too easy, and "Hardcore" is much more enjoyable. Me... I like survival, and I like not getting frusterated because I want to get to the next part of the story, as well as see much of the world... so I think "Normal" is about right for me.

One of my favorite Rift games so far. So creepy. Made me scream and almost fall out of my seat at one point. Looking forward to seeing how this game will handle with the new Oculus Touch controllers in December. Having the PDA in your face all the time gets old but I was able to look past it quite literally. My only real complaint so far with the game is the stupid white dot floating infront of my face telling me what I'm looking at. It breaks immersion and it should have a toggle in the options which for the life of me I cannot find. I also hate to think of what the white dot constantly in the same spot on my headset is doing to the Rift screen as I play. Feels like it would be burning a big white dot into the display.

Overall though one of the most ambitious, atmospheric, and breathtaking VR games to date. Totally worth 20 bucks especially because I'm sure they'll continue to improve the VR support.

Fantastic in VR. Need a bit of patience at first with settings and getting used to controls. But, this is the immersive RPG-like world I have been waiting for in VR. Such a refreshing change to pay a full fledged VR game rather than yet another early access cash grab.
