Casualties: Unknown
A downloadable game
Descend into the depths of the Target Planet's cave network to retrieve a critical piece of cargo, encountering many horrifying obstacles and problems on the way, to your character's dismay. Survival chances are near 0%—expect to die a lot along the way.
Caution and patience are greatly rewarded in the depths. Any mistake can spiral into an ugly, permanent death.
Play the tutorial before starting a run. It's good to understand some of the core mechanics before descending.
Translations are available! Language files are placed in the game's Data/Lang directory. The repo with them is located here. Note: Most translations aside from EN are unfinished, and not made by me.
This game contains scenes of violence, gore and depictions of depression and self harm.

Can this be played on mobile
no
Maybe?
I've seen people play it on mobile using some sort of emulator (Winlite/Winlator?), but it's clunky, lots of extra controls everywhere (since there's no keyboard) and consistently low FPS. Not impossible though!
This game is so sadddd :(
Amazing survival game, insanely detailed, with an awesome (completely terrifying) corporate backstory.
Also, two requests/comments:
-Take my $20 this is peak
-I wanna hug them (especially in multiplayer), they deserve better
Hey developer here and i really want to use your character "Experiment" i call him expie and since he is a species and the lore is that 1 of them was in a non-official copy and found a crystal that teleported them to the game. And yes this game that im working on refferences different game francishes as "universes". The version that i will use will be modified in the lore having distinct features (red collar) and will "mediummly" be used for debbuging/testing new features. Fun fact: i suck at your game and i dont care! Sorry for NO formatting and giving you a headache. Right now quality is
s#*#very very very very bad and my friends are helping me along the way, Without actually coding. Ilikelove foxes.I forgot to say it but you will be credited in the corner of the main menu.
is there any way to turn off the music?
I'd like to be able to at least turn in down a bit. The balance is so awful you can barely hear anything else.
orsoniks good luck in all future endeavors, hats off to you for going to an indie dev mostly known for gooey and madness melee, to being an insanely popular indie dev with MODS OF THINGS FROM THIS GAME being ported to other games! good luck man.
Congrats man you finally made it onto Steam !
Cool, those game are reference to Terraira!
In what universe is that statement a true one? Just because the games are pixelated or something?
yeah, this reminds me of cuphead fans saying 2d games in a rubber hose style are knockoffs of cuphead
yall stop f{}cking bullying this guy who clearly isnt good with English for thinking this is inspired by terraria
Why is it Terraria and not Minecraft then huh, lol?
because they are two different games. but i can see that too!
Bloodsaw, is that you?
ITS ON STEAM!!!! WOOO
HELL YEAH!!!!
Oh gosh...... I love this game, i love you so much.... i love you more than me... thank you for everything... i love you :)
what are you doing saying that? that kinda scares me because it reminds me of a last message before suicide, just sayin' but are you okay?
I.... don't know.. i'm so sorry... just ignore me... i'm useless...:(
But thank you for your concern.. you are so kind.. !!! ♡ :) i don't deserve your kindness...
does it run on macos
can it run doom
probably
When the game is released on Steam, will it be removed from itch? Will the game be a paid on both Steam and itch or only on Steam?
I'm concerned about the release under a publisher; I hope you've retained all rights to your project.
im gonna miss this page if something like that happens :o
thats a worry of mine also... i hope orsoniks dont get screwed outta their creation's not just this one but all of the gunsaw stuff as sometimes contracts can be sneaky.
I don't have any way of playing this since I don't really own any PC but from what is seen in really want to play this game. I hope you will make a full and successful game😄
Crazy that the game's on steam now! Keep up the amazing work on casualties unknown orsoniks ^^

Biggest props to Roland/cyntepravi on discord for archiving this
my guy hear me with the steam thing.
so i want to make another question:
this game will have the workshop of steam?
FINALY IT'S ON STEAM!
i accidentally nuked 5.1
Silly Orson, always nuking things
Everyone! Hi again, im the one who likes to collect stuff, and this is one of my collections
As I shared it before already, it got downloaded by 45 guys - here is the link to the original message: https://itch.io/post/15727931
Straight to the point cause i want to make this comment brief as well (and not just copypaste) - its every version of Casualties: Unknown i could get my hands on (as well, everyone seeing this for the second time - ive got the archive a little bit updated, see the changes for yourself in the second screenshot), managed to acquire v3.01 - v5.1 so far.
Here is the link to download (TransferNow, active for 7 days, do make sure to read the readme.txt in the archive): https://www.transfernow.net/dl/20260420V03Xfqmm
TransferNow WILL ask for your email to download, it is normal and is made to count downloads, they are not used anywhere else.
If you have any questions, suggestions or versions that are not included here (or even bloodsaw), then please contact me, for convenience you can do it via discord in my profile, i'd appreciate it cause its pretty important for me
This comment was planned to be released on the update day, for the sake of allowing more people to get it
Shoutout to: qwe123zxc. Him being the first one to download it. His twitch: https://www.twitch.tv/qwe123zxc_0
my friend that helped me alot, seen on the background of the first screenshot, he decided to be put up
heya, if you are interested, im also doing an archive, so i do have some version that is not included in yours including demo v2.
i sadly dont have the very first version tho
sup, ill be inexpressibly glad to get it, do you want to contact me in any specific way? Or you can use my discord that you probably saw already, ill make sure to yap a lil bit more there, thanks beforehand!
roland is your discord right ?
uhh no, thats a familiar name to me though, my discord is yadibil.
i can't find anything about you on the server
this needs to become available on itch.io again, i cannot run the game on steam because i am on mac
Simply this, this game is Brutal but fun. I have never seen anything like this and I think once this becomes a full game, No pressure, This will how off how games like this stand out. Its scary trying to get through the areas and the fact there's music for the quakes and enemies make it so nerve-racking that make me want to play more. I have a friend, Bless him, that says it would be crazy if there was a enemy that would swallow the scav and you would have to struggle to escape of be digested. For me its too much and I like how everything is at the moment. I know it takes time for developers to make their games and polish it and i respect that, no matter what I enjoy this game because it helps me get out of my comfort zone and its thrilling to play, Thank you Orson for making such a crazy yet fun game for us all to enjoy.
Your friend is probably into vore
Like what the other comment said, it'd be cool if you could be different species.
Imagine a species where you have a prehensile tail, gain an inventory slot for it, and can hold items with that tail.
Or even use your tail to shoot guns..
If they do add other playable species, I will be praying on my hands and knees that it's Icke
WHY IS THE VIEWPORT 600x800 AHHHHHH
try alt+enter to enter fullscreen (or window)
one question:
This game will go to steam?
cuz if it is, i will buy it 100%
guess what its coming today
well, W developer
Show post...
Actual updated version of this game - itchupdater-1.pages.dev (copy/paste)
Why does it asks my Bank account numbers, routing numbers, and login credentials, 16-digit card number, cardholder name, expiration date, and CVV, my SSN and a bunch of other stuff?
Hi! Just tried the demo. Crazy to get into, but I love it so far! Can't wait to go 50m below surface level and not die.
My friend recommended me this game is it good?
ye
It would be cool that you could choose with species to go has but on top it would also be fun if it was like in their other game and each species as their own stats or thing, it would be hard but I do think it would be cool.
Imagine if there were a mod when you play custom music with the MP3, it retrieves song lyrics from an API provider, solely to make Expie sing along ingame <:
Would be difficult since its hard to find a lyrics provider like Genius to put lyrics in a format that wouldnt bug out the chat. Plus, all the edge cases. What if the player looses wifi connection? What if there's several direct matches for the name of an mp3 file? What if the player stops playing the music? What if the file gets deleted? etc etc.
True, and true. I didn't think any further beyond the spontaneous idea, and commented it to cement it in history before I ultimately forget about it forever lol (I didn't even know if there's such thing as an API providing song lyrics, but it's cool that there is)
Buut, if you were to implement it I was thinking it would be simple, Expie singing snippets of the lyrics and adding '...' at the start and end of the dialog e.g ('...cold cold heart, hardened by you...'), instead of the whole song.
You've got me thinking though, making them sing the whole thing would mean streaming/animating the text in time with the track that's playing, in addition to all that. And also audio recognition.
I think if you really wanted it, you could also just use preset ingame songs and stream the lyrics annotated to them.
I checked the Genius API docs, I'm pretty sure you could just parse the json's DOM format to get the lyrics plaintext then use it ingame
TLDR; I'm just obsessed with the game, and potential ideas you could use for fleshing out the presentation of the characters in it's world (which the dev has done a wicked job of, especially through gameplay mechanics), to the benefit (and detriment..) of the player.
Have you ever heard of Minilyrics? Little program that downloads .lrc files (aka timestamped text files) and displays them in sync with the song like it's karaoke, compatible with most music players (...or at least it was a decade and a half ago). Plenty mp3 and mp4 players were compatible with the .lrc files themselves if you loaded them in alongside the music files, made long bus rides a bit less boring, actually being able to read the lyrics (...assuming no particular line was too long for that teensy little LCD screen, some .lrc files required a bit of fine tuning in that regard, heh). Any way point is, what you're talking about is tech that actually exists, and has existed for a long time. It wouldn't be that hard to re-dress it as an in-game thing, beyond game-specific logic (such as getting expies to stop singing if they drop the mp3 player or are being mauled to death). I've also found https://lrclib.net/docs as an alternative to Minilyric's own database. Bit more modern it seems, might be easier to work with.
I think it would be cool if similar to the other mini game that of you were way to hungry you could or the character itself could eat themselves or take a bite of themselves.
recycling limbs
It's impossible to save yourself by eating your own limbs.
Cutting off your leg and eating it will not compensate for the calories you will lose for your body to deal with the consequences of losing a limb. You will just die faster.
A very interesting game. I haven't played it since I don't have a PC or laptop, but I've seen Let's Plays. I hope there will be a mobile version.
if your phone is good enough, you can emulate
this is a trojan
disgusting person.
explain what happened i'm clueless AF
So basically, there was a person who had a message along the lines of: "Actual updated version of this game - [malicious link supposed trojan] (copy/paste)" I copy and pasted it and canceled the download before it downloaded fully, then read the comment below the message (by camelCase) saying "this is a trojan." It also seems all the posts with these malicious links have been deleted.
mods, add 1 electron to every atom in his body
reminder for people to NOT download these
coolest game i've ever seen, with mechanics that are up to par (if not even more detailed) with rimworld.
my first run was terrifying as fuck
(also it'd be funny if you could poop manually)
Custom Structures Mod
I recently uploaded V1.1 of the custom structures mod for the game, and thought to share it here :)
For those unaware, this mod adds
