Game is great for the state it is in, creepy women are terrifying, voice acting is mehhh. I think the sex scene should allow camera movement. Thanks for the good work :)
Oh and I'd love to ba able to adjust camera sensitivity when aiming, it's waaaaayy too high
Thanks!
The voice is generated by AI, I hope to hire voice actors when I can!
In the next version will feature customizable sex scenes (camera angles, lighting, speed, etc.).
As for sensitivity, you can change it in the settings, but not specifically for aiming. I'll fix this in future versions.
Amazing keep up the good work !
Why when I am in the menu the game is beautiful and then when I start it it's on low quality, it seems to be such a good game but on full quality
That’s probably because your graphics card’s memory is getting overwhelmed, so Unreal lowers the texture resolution to prevent this from happening. Some people have fixed this by doing the following:
Apply and run the game from the shortcut
I found a locked safe inside the Stim. Room and I don't know its password. I've been stuck here for a long time
You must convert the letters painted on the crate into numbers.
To do this, there is a translation document in E. Room 2 (Obs Module).
You can also look for a walkthrough on YouTube. I have several on my channel (TheAesthetikDev)
I'm stuck on crafting the processor. I'm still missing one of the components, the one in the middle
Check this walkthrough:
Where do I head after defeating the boss
The update ends there
not a bad game but the textures keep going between good and bad so its hard for me to play while it does that
That's because your graphics card's memory is being overloaded.
Let's try running the game using DirectX 11, as this could help.
Apply and run the game
Looks interesting, but can't play the game. Having an issue every time I try to extract it from the zip folder with the ucas file in in Paks folder. Every single time it gives me an error even when trying to copy/move the individual file out of the zip folder.
And after looking up the error, it says it's due to permissions or corrupted files or blocked access. I am the only user/owner of my PC so it's not an admin issue, and I've tried to download the game twice from here.
Try use a third-party tool like WinRaR or 7-Zip. It might be because of the tool you use to extract them aren't well supported.
Also, make sure there isnt anyfiles being blocked by firewall.
Just want to confirm that i've tested in extracting the folder and it works fine.
It does show there is a Headers warning error in the file, but i used 7-zip's test function to see if it had any issues and showed no errors.
I stuck how I continue. After I get take to Atrium finish conversation took elevetor I dont know where I need to go
You have to go to where the game starts; there's a door there that leads to another elevator.
i cant activate the elevator, i can open it up and go inside and press f on the menu but the only option is "close"
After Cira's shower, you need to talk to Eliot (the doctor) so he can unlock a new elevator destination for you. You might not have done that part. The game will notify you when a new elevator destination is available.
this is the first one and i got the notification. i wonder if it bugged out cause two of those bug aliens spawned off the girl and both triggered the cutscene when they died
oh I see, then must be bugged. You can find a save file on my Patreon, on the release post of this version. I suggest to change the file, that should fix it
wanted to say, overall its a great game. love it. ive played parasite inside as well recently so it felt pretty natural getting into it. that being said, i noticed when going to the atrium that the textures would go bland every time. and when crawling thru the vents it would go janky every time her left knee came forward before going smooth again. as for the gun.... it was difficult trying to actually hit the targets, and i couldnt kill the creatures with the knife to save my life.
iirc in the locker room on the bench
After the "tutorial" or that's what I call it, is when the real game begins.
Thank you!
About the knife: initially, it was designed solely to open doors or strike certain environmental objects, but starting with v0.0.45, I improved its responsiveness so it can be used in combat. Attacks are faster, leaving Cira less exposed, and they can now be directed vertically (these changes are because I’d like to add more melee weapons in the future).
About quests: this is something I feel compelled to add due to the game’s increasing complexity; many players can get lost, mainly because of all the backtracking. Additionally, the NPCs in The Atrium will have some associated side quests, so the game definitely needs a quest tracker.
Pls make the setting slider .00
people with ocd are gonne quit this game after 2 mins
scheduled for the next version :)
I still cannot play this game as AMD crashes plague it. will this be addressed soon ?
There is a fix:
that fixed it ! thank you so much !
Enjoy the game :)
For anyone's notice, there is a public 0.0.35 public release build available, its just on their support site.
Fortunately they are set as publicly visible, so you should be able to find it and download it from there.
Not sure why they have not made a development log post here about the update and added it to download.
But its for now on Patreon.
Sadly not on Subscribestar, as that site has rules about that.
This game has grown on me and I take my previous statement back. Parasite inside is straight up ass and this game has potential. Keep it up Aesthetik
Where do I get the tape for the broken keycard? I cant find it anywhere
Nevermind I found it after searching again
This looks very similar to "Parasite inside". Not saying it's a copy but from the images to the name it's... Pretty similar. I'll edit this once I play the game so I can have an opinion
Edit No.1: I haven't played the game yet but I have seen about 60% of a walkthrough. The main plot is similar and from what I've heard a few sound effects are the same (I think.) nonetheless this game is actually decent looking and looks more like an enhanced version of parasite inside. Will be playing soon and keep up the good work. (next edit in approximately 1-2 days. More or less)
100% the game...yeah its like a 70% copy of parasite inside...😭🙏😔✌️
oh yeah and 𝓓𝓲𝓭𝓭𝔂 𝓽𝓲𝓶𝓮👅
They definitely are either inspired or its probably the other way around, but they do have the same gameplay aspect.
The only difference is mostly on the enemies in the game, since Inside has spores while Echo has weird penis aliens.
From my take of Parasite Echo compared to Parasite Inside, Echo feels more focused on actual combat, puzzle, and survival, because its made like a Resident Evil style game in space, while Parasite inside feels like a walking simulator at most because you mostly walk and not fight as much.
(And im excluding the boss fight from Parasite Inside because its short and thats the only real combat you get from it)
Plus, Parasite Echo is thinking about making grab animations to the game, so its already giving promise of more content worth then what Parasite Inside has made, since that game has not even made much progress in total.
I totally agree with your opinion and thats what i was kinda getting at but it is REALLY fucking similar. Like way too much. Nonetheless both games get a 7/10 from me.
also i did not finish the new 4.0.0 upd for parasite inside so you just spoiled that theres a boss fight which HURTS ME
Sorry bro, was in the moment so i didn't expect it much.
I just saw a playthrough because I am NOT replaying the entirety of parasite inside and yeah the boss is mid. Plus too many missed opportunities for goonbait or smth
Yeah, the dev of Parasite Inside is just catering to vanilla content, and there is no real monster action or anything much related to parasites happening to the Protag.
Like, 90% of the sex content from there is just about being sprinkled in spore dust and get send to an area tied to a scene (especially if you played the previous versions), and its just pure vanilla (basically no actual cum scene or kinky stuff)
The only thing they did better in the current version is adding some minor hazards that you have to either struggle spam or shoot down, but its very much tame since the one you have to struggle just to get out of does nothing sexy and its only damaging and causing spore toxic.
I actually believe that Parasite Echo is going to get better at it during the next couple of updates.
where do i get code for box in stim room?
Hello, there is a note on a desk in a room in the Obs Module that helps you transform letters into numbers. If you've already read it, you can find it in the Logbook.
for some reason on my laptop it wont let me stab anything bc i dont have a mouse
I had the same problem had to quit and come back when i had a mouse
Where do I go after getting the pistol
There is a door on the upper floor of the Entrance Hall, you need to pickup the keycard next to the gun to open it
Then where?
To the upper door of the hall, the door is in front of the safe room. Exit from the safe room and go straight, the keycard will be automatically used when you get close to the door
Where is the safe room?
i think you should try Android version?
anyways the game is like very simillar to the Parasite Inside
Way to similar to Parasite Inside. Alien growth on doors, collectible cards found hidden of random nude girls. All like Parasite Inside even the atmosphere is the same. One thing is to make a game inspired by another game but to make a clone of one is rarely a good idea unless you actually improve upon it which sadly this game doesn't. Oh also this game still crashes with AMD.
Causing Driver Crashes constantly on AMD.
I can see the pistol, but I can't pick it up. There's no prompt to interact with it.
I got a question why are my graphics so bad even tho i have it set to max settings
Probably because you changed them, the game needs to restart. The next version will show a message for that.
Sorry :)
the thing is i tried that and it didn't fix i
Nice game! I know it took inspiration from parasite inside, but I hope you can do what that game lacked, more sex scenes rather than endless puzzles and lots of running.
Hey! I really liked the look and feel of this game but it wouldn't let me pick up the gun at all :(
Good job though, the atmosphere is amazing :D
Hey Dev, i got a little problem with ur game. I cant unpacking, every time comes an error message. Dont know why.
Hello, what software have you used?
7 zip unpacking
I gave it a try, but honestly, I don't get the combat. I have the knife, but it's way too slow. That is, the wind-up takes about a second, maybe two, and the recovery period between attacks is abysmally long. I also have no real feedback on when the damage frames are. Ultimately, it's just... Abysmally hard to time a swing for the first actual monster when it's jumping at me, and seemingly impossible to hit it when it's standing still between attacks, and it's unforgiving. I tried running away, too, the path forward is locked and I saw nothing in the areas I passed through that would help. So, while the idea is interesting, the combat is going to need some real polish. I'll keep an eye on the game, though.
You have a weapon near the corpse, on the blood pool. It may be difficult to see, but I have already implemented the change for the next version.
seems like a copy of parasite inside.
I thought that too
3 Problems
1. If you load from the menu (in game) the game saves any triggers and your health state
2. If you load with an enemy in the environment it despawns
3. I couldn't figure out how to kill that little enemy and nothing worked neither timing the enemys Jump nor hitting it close up
Game looks cool and im sure it has a great future but I couldnt progress past the First enemy
Yeah, I ran into #3 as well. I can't figure out if it's the end of the game for this release, or if it's supposed to be killable, or what.
There is a weapon near the corpse in the chair. On the blood. Its hard to see to some players, I'll need to change that

quick question, but what if the game starts off with Cira waking up naked from her cryo chamber and wander the ship and you the player must decide if she remains naked or put some clothes on.
Damn, man, this is really well made. Excited to see where it goes from here. One slight problem I found is that I accidentally pressed jump while in the vents and got stuck in an endless jumping loop. Other than that, really cool game.
Thank you!
Sorry for that, I'll check it :)
