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.

mutliplayer, console support... 👉👈
Greetings. I have been playing this for around 20 hours now.
I am not extremely articulate with words, please forgive me. I want to say: what you have created here is very special. This game effects me very heavily, emotionally. I have complex feelings about pain and suffering, and comfort and care. This game has made me want to cry. I think about it when I sleep.
It is beautiful. I really thank you, and all those involved in the development of this game, this world, and this experience.
I really look forward to what the future holds with it. Please, stay safe.
either this is a AI comment or your exceptionally good at writing
I loathe AI. I appreciate that you think my writing is decent.
Atleast with commands, amputating both feet will allow you to float.
I have been following this game for 2 years!
congrats on the steam version!
would LOVE if this game had Mac support
PLEASE add mac support
this game is so awesome even though i suck at it
Ayyy, glad to see your game blew up so much, always dope to see Game devs get recognition for their hard work. c:
If you go down to the end of the zone, then the opportunity to jump disappears. Sometimes you need to go back for things, for example. I was washed away by a geyser and due to the jumping restrictions, I couldn't pick up my bag. If you dig through the stairs, the continue button is not clickable, but you can continue through save and log in.
this is a unnecessary feature but you should make options for different personalities and they would respond to situations differently like maybe injuries whenever you bandage and stuff or pull out glass shards
Hello! I'd like to pitch you an idea for a game. I think it would be perfect for the game.
Specifically, I'd like to add the ability to play with Steam friends. I'd also like to add the ability to heal a friend. Hovering over them and right-clicking would open a menu with their health stats. You could help them heal wounds or use various medications, defibrillators, and so on.
multiplayer mod exists :D
Where can i donwload it?
I did mod it with the chinese translate and BepInEx but was fine yesterday unlit today when I open the game
need help pls
Great game, but i just realized this...
Once we get to the lost technology how would we go back up? I also have an idea for an alternate Last Stand quote in this situation
after recovering the Ruined Cargo and when Last Stand activates on the Accent though the different layers, instead of "Let's not give up just yet" The words "WE WILL SEE THE SUN AGAIN!" show instead.
Idk just a thought.
Didn't they said in the beginning of the game that expies never saw or will see the sun?
If I remember correctly, expies die when exposed to sunlight.
love the game never seen a reason to comment but Ivycomb made a music about the game and i need to share
name: Casualties: Unknown Song | "Down Down Down" by ivycomb feat. OodleZz
its like rainworld + noita + project zomboid mixed together into a mess where you fall a foot too much, you break all of your bones at once. 10/10
The fent sticks are my fav
where do i find the fent
in medical crates, or make it yourself
It would be great to see the "curse of ascension" mechanic from the anime "Made in Abyss" added to the game.
I'd love to have a reference or full espies in Furthia Trails.
hit me up if you wanna talk about it :3.
Please!
fantastic game! love its so so much. Can more complex items come auto-favorited so we don't accidentally craft them away?
Мне было скучно, поэтому я решил попробовать запустить эту классную игру на телефоне/планшете, и она сработала. Да, fps низкий, но это работает. Я запускал демо-версию Steam на 7.0 (это был мой первый запуск этой версии, и она не была на компьютере)
This is a fantastic game! I have been a fan of Orsoniks and his games since April 2023, with Bloodsaw being my favorite during that time. I started playing this game with my brother either in late 2025 or early 2026; I can’t quite remember which. We both absolutely love it! We still play it almost every day.
very good game i love orsoniks and play his games since april 2023 and i play this game with my brother since late 2025 or early 2026 i forgot
multiplayer + console release would be very ideal

Im talking about native multiplayer
hi guys i'm #notdead
anyway, i've finally made something new in terms of art..
if you've taken a listen to "Young Girl A", this should ring a bell or two
(( scroll down to see the art, but DO BE WARNED!! there's vague connotations for self-harm! ))
the man blesses us with more gems..
thank you bro
Hey, the pause screen in this game is pretty cool :)
i hope someone shows tutorial for people to play mac online
prolly the best game I ever played
please post the updated version here, im on mac using whisky and it wont let me install it on steam at all since im on macOS
there's three versions of the game in here if you want it including the latest version

Está genial, muy divertido, desesperante, triste; es un cóctel de emociones. Incluso ayudaría a la traducción al español en el GitHub.
the play or quit option stops you from doing drop capsule passkey. great game btw.
I've seen people playing with their friend's is that like a mod or is it on steam? i have both the steam and the itch version so idk if it's a mod could someone give me it?
It's a mod.
If your on demo 7, then the updated version is here.
Oh, thank you, game, for reminding me that this is exactly what's waiting for me in the future. I almost forgot that a peaceful death is extremely rare and I'm actually mortal 🙂👍
Man, isn't it great when indie devs force you to confront your deepest, most heath-wrenching fears, with a budget of a soda can and half a bag of chips? What a gem
Getting started guide: https://scavprototype.wiki.gg/wiki/Guide:Getting_started
Any chance we'll get a MacOS download?
the game is out on steam, youre so late (if you cant download it on steam or, cant download steam in general, im sorry)
Could you please add a way for people on web/linux to play this? I intentionally don’t have Windows, but this also means i can’t play the demo.
Runs just fine in wine / portproton.
an open letter of appreciation
the content of the Androgyny PDA log makes me (an intersex enby) feel represented and seen. it's a series of truth nukes. a truth nuclear winter, if you will.
it is exactly the kind of enby/intersex rep I wish Rain World *would* promote by making slugcats gonosimulistic, genderless, and/or asexual. yet C:U executes this better than Rain World ever could, because expies are a humanoid you're meant to empathize with, not a genuine animal like scug.
you get it, orsoniks. thank you.
the experiments werent beings of evolution
slugcats were made from evolution, thus having no way of reproduction would be unrealistic.
Just because you are a niche person doesnt mean people have to listen to you
the fuck are you yapping on about?
internet things
world's worst ragebait. slugs evolved to be gonosimulistic irl, silly
This game has been uncanny. I used to Roleplay a bunch as a teenager, and most of the lore I've been reading has been almost word for word things I roleplayed with an old friend of mine on Twitter.
You didn't happen to roleplay on twitter in the past have you? Cause this is straight up what my character Rako wen't through :sob: The Experiments even look like him :sob: /pos
cringe
:o gasp
normal
Update new version of this game - by clicking the Update button.. I feel like that's pretty obvious. Scams these days am I right?
