The Symbiant is a story-rich and erotic (18+) BL/yaoi adult visual novel about two adult men, both from vastly different worlds, embracing their sexuality and their newfound romance. It is also a tale of interstellar friendship and being gay in space!

— SYNOPSIS —


In the year 5066, Danya and his alien friend Juniper are manning The Ameretat, a humble spaceship that transports goods across the Milky Way. 

After a troubled transport gig that left their beloved ship in need of repair and their bank account empty, the team is offered a generous deal they cannot refuse: transporting a beautiful and mysterious alien who calls himself Brahve.  Sometimes at night, Danya hears strange things from Brahve's room. What could he be hiding in there? And how will it affect the connection that's quickly growing between the two men?

Content disclaimer: This visual novel includes graphic and uncensored depictions of sex between men and tentacle creatures, as well as a variety of sexual practices including BDSM and consensual rape-roleplay. All sex scenes in The Symbiant are consensual.

Hey! I would like to purchas the game but I'm from Germany so I use Euro and I have no idea no how to turn the amount frum USD to Euro.

Don't worry, the conversion is automatically done by your credit card company! You can do a regular payment like anything else you buy online. Thanks for your interest in supporting the project!

hello again I commented months ago about that I bought the 105$ pack and that I get early access to the after stories/reunion which I did but it wasn't the full game I know it was still in progress when I played it but the full game is out now but I don't have it in my downloads which is why I'm confused do I get like early access to the full game? or do I have to wait when the game comes out on march 1st? is the game sold separately from the pack I bought sorry I have so many questions

Hello again!

Have you by any chance received an email from [itch.io] recently? We sent Re:Union keys last week for everyone who had pre-ordered the game.

If you did not receive that email, you can email us at inquiry.heartcoredev@gmail.com with a proof of purchase! We'll send you a key as soon as we see it.

105 DOLLARS????? are we rich or dumb

Hello, devs!
I just purchased the Re: Union. May I ask if this Re:Union doesn't have an R18 patch? I used a translator, please forgive me if the language is rude.

(1 edit)

please download the Free adult patch here. https://heartcoredev.itch.io/smbr
Scroll down and click "Download" and put it in your game folder. ...\Steam\steamapps\common\The Symbiant ReUnion\game

if you continue having an issue please let us know.

Hello, may I ask where to download the new adult DLC?

(1 edit)

if you're talking about the new game The Symbiant Re:Union it's available on steam: https://store.steampowered.com/app/2355140/The_Symbiant_ReUnion/

if you're talking about the Adult patch: please download it here free, and put it in your game folder https://heartcoredev.itch.io/smbr

Hi devs! 

I just purchased a 37 dollar bundle here on itch.io. This does mean I can just download the after story (aka Re:union) as soon as it's out here on itch.io? Or did I misunderstood that? : ) My purchase overview does not state that, so I just wanted to make sure I understood the description above correctly. :> I so can't wait to play the main game though and I wish you a really great evening. 

Best regards Lee

Hi Lee! We are in the process of moving all Re:Union pre-orders into a separate page. You will soon receive a key for Re:Union soon through an email from "itch.io".

May I ask, if I have purchased it on Google Play, can I still get 18+ game content? Or need to buy again?

Hi ac860421! For various reasons, the Google Play game is considered a separate product, which is why it's significantly cheaper than the Steam, itch and GOG version.

If you would like the R18 content, indeed a separate purchase on itchio/Steam/GOG is necessary.

OK, thanks for your reply.

Hi dev, I'm looking to purchase the game bundle on itch.io, and I have a question:

The descrption says it will come with a Steam key. Does this mean if I purchase the extras (OST, Artbook, etc), they will also be included as DLCs on steam? Thank you!

Hi IlyaMuromets! Unfortunately, you can only add 1 Steam key on an itch product, so the only Steam key we were able to associate with a game purchase was the game itself. The extras will have to be downloaded from itch and not Steam.

(1 edit)

Ok, so if I preorder The Symbiant Re:Union on itch, there will only be 1 Steam key for The Symbiant Re:Union but not The Symbiant?

(1 edit)

If you would rather get the games on Steam, I suggest you grab them there.

This game is awesome on so many levels: Voice acting is superb and hot; Art is gorgeous; Story is wicked good; Programming cut scenes - mini and full are like a movie, so professionally done. Well done to Heart Core Dev. Absolutely brilliant. 

Thank you this means so much to us!!!
Programming-wise we took a lot of inspiration from N+C games. =D

(1 edit)

Originally the extra games were being offered with a $60 tier that's now disappeared, are those whose paid for that back then not going to get our promised access?

https://heartcoredev.itch.io/smb/devlog/380369/72-hours-left-for-itch-pre-order-...

Hello! Everyone who pre-ordered The Symbiant Re:Union (previously called "After Stories") through Kickstarter or itch will receive a key to the game. We haven't sent the new keys yet.

Weird question, but who bottoms more in this game?

I just downloaded the Re:union demo. Are the voice actors different from the main game? :O

The voice actors are the same! The only new voices you'll hear in the game are Chohra's and Riemphea's, who are voiced by Joey Sourlis and Elsie Lovelock respectively.

Oh! I thought Brahve sounds really different. :D Sorry.

Played the demo a few months back & it is easily one of the best visual novels ever made. Look forward to purchasing the full thing soon

Thank you for the kind words! we really appreciate your support!

(+1)

The thanks is all mine. Your team put in a lot of effort into a smutty VN. I was amazed to see full voice acting in the beta because well, it was a beta. You delivered a honestly life saving piece of art & I'm glad to have found it. Thank you

游戏开发者你们好!我是一个游戏粉丝,非常喜欢你们制作的游戏!你们游戏的剧情实在是太棒了!我想向我的亲近的朋友推荐你们的游戏,同时也想制作非盈利性质的同人制品和我的伙伴分享我的喜爱。(不知道这里机器翻译是否准确,就是我想绘制一些同人作品,同时把我画的图印成一些镭射票,目的不是为了盈利只是用于赠送给朋友)不知道你们能够允许我这样做吗?期待你们的回复,谢谢🥺

Hello game developers! I am a game fan and I really like the games you make! The plot of your game is really amazing! I would like to recommend your game to my close friends and also create non-profit fan products to share my love with my partners. (I'm not sure if the machine translation here is accurate, but I want to draw some fan works and print them into some laser tickets, not for profit but for gifting to friends) Can you allow me to do this? Looking forward to your reply , thanks!🥺 

hey, sure! you're welcome to do it! Thanks for your interest in the game <3

Just played the demo, and honestly-  I'll be buying this game some time in the future, for sure!

Glad you like the demo! Thanks for your support!

Is the Steam key from itch.io the uncensored version?  I originally bought the game from Steam in Germany, but refunded it. Why does it not show the adult patch even when you click on "show the hidden DLCs"? Is it only region locked in Germany? Shouldn't it be written somewhere that you have to install a patch for the full content? I only noticed the lack thereof while I was already playing the game.

I know there`s an adult patch for Steam here, but after trying to hook Textractor to the game it kinda broke on my computer(text was overlapping). 

(1 edit) (+2)

Hi Papierbluete. To answer your questions:

  • The adult patch, like all adult content on Steam, are banned in Germany
  • We are literally not allowed to talk about the adult patch, or even IMPLY THE EXISTENCE of the adult patch on Steam. Not in the product page, not inside the game itself and not in the newsletters
  • What you're asking is thus completely impossible, and outside of our control. Doing what you're asking would ban the entire game altogether from Germany. We know, it happened to us before
  • However, we put the adult patch for free on itchio here. You can place it inside a Steam-purchased game
  • On itchio, we have no such restrictions. The game comes uncensored by default on the itchio version.

Is there any particular reason you're using Textractor?

I see that sucks:/ what reason does Steam have for banning it? 

Textractor to hook the text for language learning purposes.

(+1)

Long story short, Steam is forced to comply with German laws.

¿Si compro el juego desde Steam y tengo la cuenta conectada, podré descargar la versión para android en el móvil? es por hacer el pago desde la cartera de Steam pero quiero jugarlo en el teléfono (la versión +18 con todo el contenido)

Hola ! Si compraste el juego en Steam, envíanos el comprobante de compra (por ejemplo, correo electrónico de confirmación) al siguiente correo electrónico: inquiry.heartcoredev@gmail.com

你好,我在steam上买了这个游戏,但是没有dlc没有办法解锁格外内容,我在steam的通讯上看见可以直接询问获得dlc,大概是回答“想吃肉”?Hello, I bought this game on Steam, but there is no way to unlock special content without DLC, I saw on the communication on Steam that I can directly ask to get DLC, probably answering "want to eat meat"?

您好,您可以下载"adultpatch.rpa"并将其放在"/TheSymbiant/game"文件夹中安装成人内容DLC。

Excuse me, but where do I download this? I don't seem to see it here

https://heartcoredev.itch.io/smb-18patch This link should work.

(+1)

thank you very much!

Hii, sorry if this a stupid question but is the main game completed? I want to buy it but I don't know of its episodic/ still in development!

It is! What's currently in development is the fandisk / extension of the main game's endings.

(+1)

I bought the 105$ pack when the game came out but will I get the after stories as well or do I have to pay that separately 

(1 edit)

Everything is included in the $105 pack, including the After Stories!

In fact, should be able to see the Early Access version of the After Stories in this page's downloads.

(+1)

I loved this shit it was great good job

<3

Sorry,  but I keep crashing.   Right after Brahve goes to bed then you see the cockpit, says some line about jumping into space, then it lags twice and crashes.   I'm running the program thru the website on my android phone.   I plan on buying the vn eventually.   I really like the art.  Actually your other game synthetic.....  ian the biot,  actually crashed too, but I think that was my fault.   It crashed after I hit the go to other apps button.  I have meat hooks for fingers alot.  With the biot vn I was about 2 hours in and forgot to save...    I really like it though, another one I will be buying when I can.  Ty for making them.

(+1)

"Good" Ending 2 hurts so much T^T Maybe I'm on edge 'cause a VN I read the other day turned out to be *brutal*, but all I want for these precious boys is one unambiguously good ending, and one *even better* ending. I hope After Stories comes out soon to heal my heart. 🥺 

(+1)

oh, no, I just read when AS is coming out! all right..... I'll just play the best route again and bask in the happy there.

Hope you liked the ride! :D

In the first after story that takes places after that ending, Danya and Brahve definitely need to work harder to get their (eventual) happy ending.

(1 edit)

*SPOILER* *SPOILER* *SPOILER*



I was hoping for an expanded cg scene, when main character first meets the symbiant and it shoves its tentacles down his pants, where you could choose to let the symbiant keep going, and it progresses to it unzip his pants and taking them off. Then you can see the symbiants tentacles sucking him off. Also I can imagine the symbiant having mini tentacles inside his tentacles, and it would have been hot to see them explore the main characters peehole. 


*SPOILER* *SPOILER* SPOILER*

You are a talented artist, and game dev. I hope you make more content like this. 


Maybe a love story about wizards? I know wands out is on steam, but the quality is terrible, and too silly. 

(+3)

Sometimes I read something and I just know it comes from a F95 user.

(+2)

I really loved this and so did my girlfriend although me and her were just like "KISS ALREADY BISH"

Glad you and your girlfriend enjoyed the game! :D

yeah, good job on it!

Gi it keeps saying it cant oatse the apkHi i downloaded the apk but it keeps saying it couldn't parse the file

Hi can you please show us the error message?

I’ve attempted to buy it again, but it still won’t work, neither did I get a notification of a purchase, 

So I have now spent at least $50 on this..I feel bad for being rude 

Please send us an email through inquiry.heartcoredev@gmail.com so we can figure something out. If your payment didn't work that means you were NOT charged.

Additionally, if itch doesn't work for you, you can try buying the game on Steam instead: https://store.steampowered.com/app/1883090/The_Symbiant/

Hi. First, I would like to share my appreciation for the game, I liked the stories, the CGs and most of all, the voice acting. ~  

However, recently I reopen the game  and the images overlap, from the background to the CGs... I tried to redowload the game, but the issue remains. 

ex: 

Also, I've purchased the pre-order version of the game (35$) and I didn't get the after-story part 1 pre-order version... (Is it normal ?) 

Thank you in advance Heart Core Dev,  J.

Hi Jaunathan, this is a common issue if your graphic card drivers are out of date or if you're using an old computer.  

You can try the following method:

  1.  hold the SHIFT key while clicking the game launch button
  2.  a grey screen will appear instead of the game, that's normal
  3. select "Force GL2 Renderer", then "Quit"
  4. Restart the game.
  5. If the issue persists, go to that grey menu again and select "Force ANGLE2" Renderer" instead

Please let us know if that helps. As for the second question, the After Stories aren't out yet because we haven't finished making them...! That's why purchasing their "tier" right now counts as a pre-order. You will be notified when they are out. We are hoping for Q1 next year.

(+1)

Hello again, 

I've tried the second option, and----- It worked ! Thank you  (I really thought the issue would persist). And, thank you again for your answer, your instructions.. 

I'll wait patiently until the next uptade. J. 

Hi! If I purchase the game here instead of steam, do I still need to download and install the adult patch manually? And if so, if I buy the game on steam, is it still possible to merge the patch with the steam version? I'm afraid I'm a little confused on how best this works :) 

dunno if you ever figured this out but the adult content is included in the download from this page. the patch is *for* the steam version.

is after stories 2 out yet cause when I go into the after stories it brings me to the first one

Hello! The After Stories aren't out yet, so if you paid $28 or more, you get the game and a pre-order of the After Stories. We're planning on releasing them on Feb 2024 at the latest date but hopefully sooner than that.

so even if I bought the 105$ pack I don't get the after stories with it?

To sum it up:

  • $28 purchase will unlock the After Stories after we've finished and fully released them
  • $105 purchase gives you early access to the After Stories, which is otherwise only accessible on Patreon right now

Hope that helps.

Hello dear developers!

I am writing to you on the subject of a steam ban for Russian players. About a year ago, they banned the page of the game called My Time At Portia. Recently, it has become available again for Russian accounts. So.. maybe it's just a bug? Or is something mixed up or missing? I suggest you talk to the developers of the game My Time At Portia, maybe you will figure it out))

I really want to play Symbiant DLC, so don't leave us!) Bye! =))

(2 edits) (+1)

This is very upsetting because Russian is the first language The Symbiant was translated to and we know many SMB fans are from Russia.

But aside from asking them what happened, there is nothing we can actually do on our own to reverse the ban beside asking nicely. Perhaps they will answer faster if a lot of people ask them directly (through forums? creating a ticket? an email? I don't know) but we don't want to get other BL game developers and Russian fans in trouble either.

My Time at Portia's case is quite different, and they don't seem to speak English, so I'm not sure they will be able to help us. Thanks for the info bit though!

(+1)

Thank you for the answer) And for your wonderful game)
I hope all problems will be resolved in your favor =)

(I will still buy all the DLC if they are available ;ъ )

So, about that.. we have received a confirmation from Valve that they have been contacted by Roskomnadzor demanding that they permanently remove the app from the region. Which means that Russia officially banned the game. :(

(+2)

It's sad to hear that.I wish our government wasn't so homophobic.Even as hetero, it pains me to see how they negative relate to everything related to LGBT.

(+2)

Hello, 

I bought the game on steam. But in Germany the adult patch is banned maybe ? 

Can i do something? 

Or when i buy it here, can i play it then? 

Sorry for my questions, i'm a little sad about this :(

(+2)

Hello! You are in the right place to get the patch. It's the "adultpatch.rpa" file in the demo download section and it's free!

If you need instructions on how to install it, you can read them here.

Thank you so much 😭 it worked. I'm so happy now

Enjoy the lewds! =D

Why did you block access to the game in steam?Is there a special reason for this?A month ago it was available, and now access for my region is closed.Which is very sad.Since I wanted to buy it in the near future.

Upd. Nevermind

Just seen last tweet about ban .Our government is really dumb.

We asked Steam staff about it last week and we haven't gotten any proper answer from them. All we know right now is that Valve is the one who banned the game from Russia, not the Russian authorities. We asked them on un-ban the game, but we can't guarantee anything. :(

(1 edit)

I'm sorry that I lost my temper without understanding. I don 't dont mean to  be rude .This is very strange, considering how many LGBT games are available in Russia (I can freely buy any of them and have more than 20 on the acc), but for some reason they banned yours.I wonder if Valve trying be safe,since  LGBT laws get more stricted evey year here.But the same Dear Monster came a bit earlier  in january and they did nothing against it.So i really dont understand,why Valve did this with your game.And i sorry that you have to deal  with all these restrictions and problems.

Are Russian cards still accepted  if I decide to buy the game here?

No worries, we really hope Steam unbans the game. As it turns out they're the ones who did the ban, not Russian authorities.

Itchio accepts Paypal and Stripe (credit card), but we're not sure it's going to work for you.

Hello! If I want to play the NSFW version on Android, can I just purchase from this link?

Yes!

(1 edit) (+3)

I love this game and I keep replaying the sexy stuff. :D I love how it's hot and "kinky" while still being very gentle and loving. <3 Can't wait for the afterstories! (Oh and of course, the voice acting and soundtrack are aaaweeesooomeeee!)

Thanks for leaving these super sweet words on this page! We're glad you enjoyed the game <3

Is there a way just to pay for the after stories?

We will create a separate page for the after-stories soon-ish. :)

Hi, just wanted to let you know that GOG has a broken download link to Symbiant adult patch and they have been unwilling to fix it for about two weeks now. So if someone buys the game over there and wants the patch they won't be able to get it.

(1 edit)

Greetings, we are sad that you had to comment on itchio in order to reach out to us. We tried updating the build through GOG's tools but it's still stuck in the oldest available version. We reported the issue to them and they'll probably get back to us next week.

In the meantime, the adult patch on this page should work if you haven't tried that yet.

(1 edit)

I’ve commented before on this, which was completely my fault since I clearly can’t read properly, but I’ve bought the game, and yet, I can’t get past the demo, on steam or Ichio, 

it is a tad bit disappointing as I’ve been looking forward to playing this, the demo was quite good,

(1 edit)

Hello, are you able to download any of the "FULL GAME" files? These are the ones  you are looking for. You are the first person reporting this issue.

I attempted too, but it either crashed my computer, or showed up blank

I also didn’t receive an email about my purchase, or a text message

(+1)

hey! i purchased this on steam and i dont know why i cant see the plus 18 drawings? even tho in steam i clearly put im older than 18 years old.do you know why that happens?

Hello Zeiya,

Are you from Germany or China? If so, your country's laws prevent Steam from installing the 18+ patch. If you're not from these countries, then can you please check whether the game's Adult patch DLC is enabled in the game's steam settings?

(+1)

ohhh that was the problem!! tysm i really appreciate

You can find the adult patch in this page. Link to installation instructions is at the top. :)

thankiu!!!

Deleted 21 days ago

Hi Alicys, this seems like the purchase page and doesn't seem like itch counts the game as purchased on your account. We haven't been notified of someone spending that amount either on our end.

just finished four routes and OMG our boy Danya is so hot <3 thank you for making this so my fantasy could be fulfilled <3  are there after stories coming? if so when are they coming? wish the dev could add some more kink elements to it (like rubber/latex/transformation/alien impregnation xoxo

yass

the good ending made me tear up goddamn it

also props to the dev for making juni more relevant because representation matters 希望后续赶紧出来呀
