About This Game

Hey you, reading this game description…what has your life become? What have you chosen to do with your precious, limited time? What have your gained from it? And what impact have your choices had on the people in your life that love you?

You wake up on a base in a new, unexplored planet. Your landing craft is torn to pieces and your gear is scattered. Why are you here? What is your mission? How will you ever get back home to your family?

Corpse of Discovery is a thought-provoking first-person planetary exploration game located on 6 unexplored planets. As the player, all you know is that to return home, you must complete the mission at-hand for the Corps of Discovery. However, with each mission completed, you’re left with unresolved questions and zero answers.

The Gameplay

While contending with extreme and harsh conditions, such as intense storms and unbearable heat, you must remain determined while completing missions for the Corps of Discovery. You’ll meet AVA, an AssistBot who will accompany you on your journey and make sure you’re constantly reminded of your importance to the Corps. However, you have only one goal in mind: to get back home to your loved ones.

Finding What Matters

Corpse of Discovery looks at our lives under a symbolic microscope and examines the inner workings of the choices we make, ultimately culminating in the crucial question, “What sacrifices will we make to be successful?” As you struggle to complete each mission for the Corps, you are forced to grapple with your humanity, who you are as a parent, a spouse, an employee, and a human being.

This game blasted me away - don't listen to the bad reviews, most of them did not understand the game. Maybe you have to have made a special kind of experience to aknowledge and value the metaphor that is being told. It is an extremely deep, meaningful gaming experience, that transports an important message to all workaholics and career-fetishists. Additionally it is filled with humour, witty comments, smart cross-references to pop-culture and the gaming industry.

If you like intellectual & philosophically challenging games like Ether One or Mindpath To Thalamus you definitly should give this title a try. Explore the details. Enjoy the weirdness. Wait for the mind ♥♥♥♥.

I highly recommend this title, although I fear that not many gamers will have the patience to experience the whole master piece (which is a pity). Thank you Phosphor Games for an utterly interesting game! I hope that you took the moral of your game to your heart during the development of this title itself ;)

This game is so weird, I have no Idea where to begin. Maybe I Should start with the bad things fisrt.

So I had two cons about this game

One, the optimization, Oh lord, the optimization is poor. My frame rate was terrible and I had to have my settings set to low the entire time, and I STILL had crap frames. It was terrible, but I paid the 15 dollars for it so, at first, I thought, ok lets just push through that and see what the game has to offer gameplay wise.

My second and only other gripe with the game was that I would occasionally glitch through the floor when I would jump, so nothing to out of the ordinary there.

As for the Pros, Well...

The first time you wake up you're on your ship. Its a pretty self sustained looking palce....but you've just crash landed due to some unseen force, so the automated messages play thoughout the ship and have you walk through for your mission breifing. after that, once those doors open, things get weird, The good kind of weird. Throughout the first half of the first planet you're on, this robot, the AVA if I remember correctly, walks you through your mission, which is placing becons on the planet to map it out while she calls for a distress signal. once you place the becons down, she says she can not find a signal and tells you that you will die alone. She then loses all he battery power and drops to the dirt, lifeless. and now you're all alone right?.....Right?

The events that happen after wards? well, you need to play this yourself if you can, because I woulnd't want to spoil it for you. Is it worth 15 buckaroos? I would wait for it to go on sale, maybe catch it at 10 or hell, I bought this at 10% off and Idont regret it. If you got the money to spend, I would recommend getting this and playing it through. From what I could tell, it controls nice, the story is incredibly amazing and as of this review, it leaves me wondering what happens next.

Oh, and if there just so happens to be a content creator ("youtuber") out there reading this. I think It would make for some pretty decent content.

Played through this game today.
It was a beautiful game with a fairly interesting story, although presented in a somewhat bizarre fashion. Sort of similar to Lifeless Planet in this regard. However, unlike Lifeless Planet, this game just kind of droned on. It took me a little less than three hours to complete, and I really wish it had taken about half that. It became a very boring affair going out to basically do the same things over and over with minor changes to your base in between. That actually kind of killed the immersion for me.

As far as the actual gameplay, it was pretty smooth. It's an exploration game, so you really just move about, jumping and when available, using your jetpack to navigate alien planets. You will interact with your objectives, but mostly you just take in the visuals and listen to what also seemed like overly long dialogue.

Now, I dont want to pan this too hard because it is evident that this game was a labor of love, and it definitely had its positives, but overall, I just ended up finding myself bored. The pacing never changes throughout. Just sort of you wandering at what amounts to a casual pace with, as mentioned before, somewhat droning dialogue.

I'd say it is worth checking out when you dont have anything else you'd like to play or simply want an interlude between other games, but I'd also bet you will end up feeling bored like I did.

5 out of 10 for me personally. I'm giving it a no as a recommendation because, like I say, it ends up just being boring.

You control an astronaut waking up on a space station as a recorded voice wishes you good luck with your mission, after listening to a message from your family and your mission briefing you set on the planet while an hovering robot blurts out mission parameters and HR slogans.
The aforementioned story doesn't have to be taken at face value though as Corpse of Discovery wants to use it as a metaphor: while the game has an interesting premise and some good moments its dull gameplay and ham-fisted narrative hold it back.


-the art style is pretty nice

-good soundtrack and voice acting

-the first levels are interesting

-there's a good amount of dark and vitriolic humor that makes you both smile and think

-some dialogues are pretty good and function as high points in the game


-graphics are a bit of a mixed bag, while the levels look from decent to nice the draw distance is bad and there's some noticeable graphical glitches, the framerate can also be dodgy at times

-repetitiveness sets in after a couple levels, this is made worse by the amount of ground you have to cover between points of interest and some instadeath threats that'll see you go back to the previous checkpoint

-the narrative as a whole is pretty awkward, most of the time it's content to just be obscure but when it's time to make a point it comes out as too obvious and cliched


Corpse of Discovery is off to a strong start with its mistery story and weird locations to explore, sadly its attempt at a more active take on walking simulators doesn't always work well: jumping and jetpacking around is quite fun but it eventually grows dull when you realize there's quite alot of space between objectives, even more so if you want to explore optional stuff, and that getting there is for the most part a boring affair.

The story also takes a dive once you realize it's used as a metaphor about something else, sadly it's done in an unoriginal way for the most part: without spoiling anything the point the game tries to make also explains it being deadset on giving you task after task to grind through, too bad this intentional repetitiveness helps the point as much as it hurts the gameplay.

All things considered I can't recommend Corpse of Discovery, a few good points notwithstanding its story and ending were ultimately not good enough to make its dull gameplay worth slogging through over and over.

The game can feel a little janky/laggy sometimes, and the controls a bit wonky however the procedurally generated worlds are incredibly fun to explore.

If you got a couple hours to kill this game is a pretty good buy for its current price.

If you are looking for slow burn horror sci-fi game in the vein of movies like Event Horizon this game will appeal to you. Be warned that this is not a FPS game and you spend a good portion exploring the world and unlocking story elements. The game play is streamlined and easy to pick up. The graphics are good and what you expect from this price point. A fun and short game that is worth picking up and spending a weekend with.

Disclaimier - I usually like interactive storytelling done this way.

The framerate seemed lower than similar games played on my crummy system, but not so bad that it hindered anything.

The presentation and writing are strong. It's oddly introspective... or maybe that was just the mood I was in. Also somewhat creepy. Pacing and hidden details kept it engaging until the end.

I saw some of the marketing stuff for this game at some time, but I forgot about it until a friend brought it up. It was worth picking up.

Want to know if you should buy this game? Check out the first 20 minutes of game play and my impressions here


Not as bad as some of the reviews made it out to be. So what if a game doesn't have pistols and aliens chasing you? The devs had enough balls to do something they thought was unique, and I have to admit I kind of like it!

Corpse of Discovery begins like the book, The Martian, where an astronaut is stranded on an inhospitable planet, presumed dead though in this case, he doesn't seem to realize it. There's not much in terms of gameplay here with the exception of being able to jump and a requirement to hide from the sun now and again. CoD is more akin to a Dear Esther, a story told through environmental exploration. There are some performance optimization issues for sure, but what I saw out of my inital 30 minutes was enough to want to continue. Quiet, aware, and oddly beautiful.

I never write reviews, but this is a waste of time and money. Poor optimization, gameplay is dull, narative is interesting but completing the game in under 3 hrs. feels like they didn't even know where they were going with it. (alot of that time was troubleshooting the frame rate issue). Pass on this.

Corpse of Discovery is a game which sees you re-awaken time and again as an astronaut/explorer aided by an EVA unit and tasked to mark or discover various items. Each time you wake up things have shifted and your environment has changed. EVA is droll and satirical in her attempts to motivate you. It is on one level a surreal moebius loop and on another a dark dystopian nightmare.

In terms of gameplay, this is nothing more than travelling to locations on each new planet and interacting with each find at that location. This is spiced up with the addition of a jet pack and platforming elements which bring in a nice verticality to the usual 'walking simulator' mechanic. Let me say, that the planet environments are gorgeous in a No Man Sky style (although this games obviously predates that 'game'). It is a joy to jet-pack through some of the later planets.

Simple game-play aside, Corpse of Discovery unsettles you as the loops unravel and unwind and a darker narrative emerges. Satire and absurdity combine with chilling mood music and the lovely droll tones of EVA's voice to really unsettle you. As for the ending - as with all good philisophical sci-fi, it leaves you adrift a little and throws the meaning into your own hands.

This worked for me - others will find it simplistic or perhaps a cop-out. I enjoyed this game - especially after the decale of NMS. Yes, it is short but in terms of mood and atmosphere, it works.

Tries to be gorgeous, deep, and surreal; add in some lame repeticious platforming and it comes out with a 'Meh'.
Most of the philosophical themes have been done before, and much better. Technical issues, and an almost complete lack of innovation and interactivity turn a good concept into a very forgettable experience.
If you're hoping for 'Dear Esther' in space, this isn't it.

Corpse of Discovery is an appealing little game - slightly excelling the "mediocre" tag for me. Basically you play to find out bit by bit who you are playing. I had an entertaining evening with this one.

+ Good atmosphere
+ Okay graphics
+ Okay story
+ Not too long
= Secondary missions/experiences disappear when fulfilling a primary goal
- A few glitches

Since the game and its story bank on their discovery, not too much should be said about the game.
Early on, navigation was a bit frustrating to me. That was until I got tools to more easily get around.
The story is driven by inspecting objects and largely by your accompanying A.V.A. unit which might be considered a more relevant counterpart to LoZ's Navi.
I don't quite agree with labelling this a walking simulator - specifically since there is quite a bit of 3D platforming. But yeah, the game isn't too exciting.

You might enjoy this game if you like a bit of exploration and discovering. If so, come and find the story behind and all the meanings of Corpse of Discovery.

I'm honestly surprised I didn't like this game. I usually have the patience for so called "walking simulators" and usually enjoy just exploring. The problem with this one is that it teases you with the possibility of a purpose but then...the purpose is pretty boring and quite repetitive. Meanwhile, the great mystery of it all unraveled so slowly I no longer cared what it was by the second level, at which point I was just annoyed by the fact that I couldn't really see where I was going over the grass and the compass barely worked. I guess my patience only lasts if there are tiny bits of satisfaction along the way, and this one was mostly only boredom and annoyance. Luckily, I got it for $3, so no harm done.

Walking simulator... with jetpacks! A fresh, interesting twist. Beautiful graphics, nice music, touching story with good voice acting and a bit of humor. The amount of challenge is just right and jetpacking feels good - which is an achievement. No technical issues in my experience. One thing that was a little unexpected is that the game is quite demanding - a card like the R9 380 is barely enough for high settings. Overall, very pleasant experience.

This game takes the phrase "rinse and repeat" to a whole new level. You start off on a planet, shipwrecked, with an AI bot, to interact with a bunch of items all over a planet. Then something happens with your bot, the screen fades to black, and you wake back up in the bed to do it all over again. And thats literally the entire game. It gets old after the 3rd time, and I found myself ignoring most of the little interactable things and sprinting through the messages because I was sick of doing this over and over again. Each time you go outside to a planet, and they all look and feel very different, and are quite beautiful and with good graphics. The problem is there is nothing to do besides run around to item points, and the planet looks pretty much the exact same the entire time, so the coolness wears off after 2 items. Unfortunately each time you have to get like 6-8 items, which are spread super far, and take forever to get, for the sake of wasting time and increasing game length. There are these random guys that fly around with visibility cones, and yet even when you're far way they seem to know where you are and come right to around you, or if looking one way will quickly start looking over your direction, and even if you are out of the cone you get caught, starting you back at the last place, making you run all the way back.
There's not really much of a story. This is one of those "exitenstial/inteprative" stories where nothing makes sense and everything is a symbol......blah blah blah. In the end it just means they couldn't come up with anything concrete. Then the end comes that you saw coming from the start. Also I fell through the ground multiple times and was able to step into walls and look through, so they didn't perfect their textures.
In the end the only cool part is the first 5 min spent at every planet, the rest is a waste. The game goes on for too long and wears out its welcome after 30 min of a 2.5 hr game.

The Game was MEH at best the story was interesting at first, but then I realized it is just a retelling of a story that is overused and this game does not make it any better. NOT worth 7.99. I wouldn't play it even if it was free.

The story is just a retelling of the stages of death and the game does not do anything new with that story! =(
