A downloadable game for Windows, macOS, Linux, and Android


(Adastra contains themes of an adult nature - you must be 18 or older to play)

Adastra is a romance visual novel with a whole bunch of sci-fi and political intrigue mixed in. You'll experience the perils of navigating an empire in turmoil while deciding who you should and who you definitely shouldn't trust.

It all starts while you're having the time of your life in Rome on a study abroad program. Just as you're settling in, you're suddenly abducted by an alien. What does he want from you? Well, he doesn't seem to want to tell you, and before you know it, you're millions of miles away from Earth on your way to an empire you know nothing about.

It's a climate of turncoats and backstabbers, and you start to wonder if the alien that abducted you is the one person you can trust the most.

Our wonderful sprite art is by the artist HAPS, who you can find on his twitter.

The background art is by the also wonderful Blacksun who you can find on her furaffinity.

I made an account just to comment here - I mean this when I say that this is the best "book" that I've ever read. The writing is so f*cking good that this occupies a permanent place in my mind. I was eating in a Mediterranean Fusion restaurant and looked up to see olive vines. I was immediately reminded of Adastra and was filled with such a strong feeling of sadness and of happiness - my absolute love for this universe and the sadness that there is no more of it to consume. I do not doubt that it will be expanded and I can repeat playthroughs but the feeling of first going through the pages upon pages of text is equal to nothing.


I know this is true for not just me when i say this: "I'm here to replay this for the 3rd time"


I read it again and I'm happy + sad at the same time.


Got peer pressured into playing this, but I don't regret it. This is the only game that has made me cry, and easily the best story I've ever seen in a game.

Is there a 'no-graphic-images' mode? Doesn't need to be a 'sfw' mode, I know the sex can sometimes be inextricable from the story and the themes, I'm just hoping for a mode where I don't actually need to look at the D if possible. Came here on the recommendation of a Patricial Taxxon video, and I'm super interested in this story-wise, but...

(Haven't given it a dl yet)

So, like Nekojishi's Steam version without the NSFW patch? No, not really. There's a lot of nudity in the game, but only a few very explicit sex scenes that serve a purpose, so you kinda can't go without it. Sorry.

I am NOT into this


Since it's so popular ,crrated by the echo project,will traumatized you and is similar to FBTW I'm gonna play 


FBTW is just a copy made by a bitter man.


Spitting straight facts



Because sequels.


i have been crying over amicus for a week now, i promised myself that i would forget him but here i am crying, it truly shows how amazing this game is, although there's this one question i always had in mind that needs to be answered, will amicus and marco reunite? i want to know, i NEED to know.

Small detail, but the human count is 8 billion now compared to when Amicus asked MC how many humans lived here after saying how many wolvens lived. I have this game in my mind for years so immediately when I heard the world population is now 8 billion I thought of Adastra XD


Me personally, if I got kidnapped by such a wolf, I wouldn't react how this human did. :-\


so how do i save the ost cause i love em

It's in the game folder. Adastra/game/music
The files are in OGG format though, so if you want like MP3 formats, you'll have to convert them manually (which is pretty simple) and copy them to another folder. Just don't cut or move them out and it should be good.


This is the first Furry VN that introduced me to the Furry VN world it's been almost 2 years now <3


Cassius redemption arc in the sequel please and thank you.

How do I save in Android version of this game, when I'm trying to save it's saying error occurred

Hey soo i played the game all the way up to the hot springs part on android, but now that I've downloaded the latest version for windows i cant choose what chapter to start on is this fixable or am i just dumb lol


Yep, nevermind im just dumb lmaaoo


I just had a dream about Adastra, I think once you've got me there, you've done something right. 


Making a little Cassius cosplay for Halloween


Lookin good, dude!



Oh,what a cute expression!(

looks great!

Thanks, tried to catch the whole "Cassius" personality.

I've got a question about your menu, like the save and load screen and options screen, I've seen many other types of games with this same type of screen and was wondering if you use a certain system or app to make this game?

Says in info it was made with Ren'py



Y'all got me to buy the plush.
I don't regret it even if I'm a grown ass man.


We buy whatever we want that's final periodt


Just finished the game recentl;y and i loved it!!

This is my first time playing a VN in a longgg time and i gotta say, this is the best introduction to VNs for someone that is fairly new to it! and i hope to see more with khemia and interea! ^^


This was the first visual novel i ever saw, and im sad because i started with the best one first. Highly recommend, very interesting plot and cast of characters. I am in love with amicus.


Hello! Is there an Official Discord Server for anything from Echo Project? Thank you!


Just finished the game

It made me cry multiple times, the story, art, character's personality and other stuff are amazingly well made, I loved every bit

If you wanna start on visual novels, this is for you, it's 100% worth your time, I hope theres more Adastra in the future

Thanks for creating this masterpiece <3


I really enjoyed this, Nicely done. 

I like the companion story and the sequel.  I look forward to reading more of both of these, along with an ending wrap-up.

Let me know if there is any help you might need.


Na primeira vez que eu joguei o jogo no final dele eu chorei tanto que quase n茫o terminei #Amicus


(Another Topic)

The ending had me stumped. What was going to happen next? Is there going to be a sequel? I don't know.


Yes, there will be at least two sequels. There's Interea (the last three months on Adastra, just more details and lore), then there's Khemia (Neferu's story basically with Scipio, a new wolf MC) and after that there will probably be at least one, so the reuinion and all. But there's room for a lot of stories, if they want to do it.


Cool I hope they do actually do one where Amicus and everyone has a reunion over the years.

I am so hoping for that reunion. I got so attached to the characters it would suck if we didn't get a proper ending for them.


What language are all wolves in Adastra talking? Is it Latin?


Not quite, Latin is a human "brutalization" of their language.

Kind of in the same way that Latin is to most modern languages today.


So is it, or not? I think they also mentioned Italian in a part.


In short, yes. You can see stuff like "Edapol!" and "Ave!" being said by them.


So almost like a combination of the two languages?


Yes, basically what it is.


An evolved, more modern form of Latin that resembles Italian at some point, if I recall correctly.

i don't remember it being brutalization of their language it's litterally the same one with like different dialects


Well, I guess this is me being 'that guy', but—keeping things vague so as to not divulge too much of the plot— it seems like whether or not you enjoy this VN hinges entirely on whether or not you like Amicus, and I'll confess, I don't really like him. Like, at all. Amongst other things, but that would get into spoiler territory. Regardless, the comments are mostly positive, so I'm glad that others enjoyed the game. I guess it just wasn't for me.

That being said, I'd love to see more about Virginia. Easily the best character in the game.

(1 edit) (+1)(-1)

Well yes, he's the MC in the end. Him and Marco anyway. That's the point.

I feel like Virginia is way overrated actually. Cold and distant older sister tropes just aren't very interesting. Combine that with that attitude (because she's smart) and yeah no. I don't like her. Cassius was more interesting even with his inferiority complex. I feel worse for him than for her. I would rather see a genuine redemption arc for him than whatever it is they might do with her. He just got the short end of the stick.


Fair enough. I like Virginia mostly because she has to deal with a lot of shit inherent in Adastran society that her brothers don't have to, and seeing how she navigates it is a very interesting story to me that sadly doesn't really get explored much. Though given this is a VN about hot bara wolf men I wouldn't really expect that subplot to get a lot of focus.

I'd probably like Cassius more if his initial reaction to Marco wasn't to immediately want him dead. I unno, he really didn't sell me enough on there being a good or understandable side to him to let me empathize with him despite his behavior. 

I've more to say, but that's probably getting more into my personal hang-ups than legitimate critique of the story itself. Like I said, I'm glad other people enjoyed the game, even if it wasn't for me.

Hm, actually, no, I think I can better express what I meant there. When I say, "whether or not your enjoy this VN hinges entirely on whether or not you like Amicus," I mean that he's supposed to carry the entire story. Without him there's really no reason to care about the planet, er, moon Adastra and all the other stuff. It's a pretty place, but God damn, it is not somewhere you'd ever wanna live. I kinda wish they'd focused on that more outside of and without Amicus; that way he wouldn't have to carry so hard.

Yeah, that's what I meant by "that's the point". Like, the story is really about him and the human in the end. It's all good, and to each their own. But to be fair, it WAS written as sort of a break from Echo for the writer. And if you played Echo, you know what I mean when I say it can really mess with you. That's why the focus is more on the big wolf and all. Which I don't mind personally, but I know  isn't everyone's cup of tea.


When I was told this is like comfort food after the other projects like Echo I didn't buy it but I get it now. It puts my heart at ease. I get it now. I really do.

Para variar no hablo ingles, pero aun asi tengo en cuentas las bellas ilustraciones y composicion de la historia que nos regala Echo Proyect

Me encant贸




It's been 3 to 4 months since I downloaded this novel... It rly changed my life by opening the whole new world of content (especially furries). It was sincerely not the first time feeling being connected to the fictional character, but damn that was one of the most breathtaking and heartwarming :)

Tonight I was walking outside, listening to perfect imo OST to Adastra. "love" started to play and I decided to look at the sky. I saw so many bright stars... I started to fricking cry and laugh (of happiness I guess). I "saw" him there, I hope he is there. Somethere in the sky, in the space there is that Himbo wolf Amicus waiting for his Marco. Beautiful story, indeed.


Man Im So Addicted To Amicus It's My 2nd Time redownloading the Game and playing it again I Mean we all cant Lie Amicus is a hecking Cutey


I think many of us has read theough the entire story at least twice



Loved the story and all the characters and soundtracks, i started to tear up near the end. The soundtracks in this game are so well orchestrated and everytime you hear one it feels as though your soul is being uplifted, was definitely my aspect of the game.

Such an amazing story !!馃樆

I hope the update will be released soon and maybe somme more news chapter...馃

Otherwise I'll be crying every day !! 馃槶

Hm, actually, as good as this is, you know what would make it even better? A slight rewrite of the whole final act. Remove THEM from the story, make it more about the MC wanting to do it himself, change THAT event so it makes more sense within this context, and there you go. The story works much better when it's slice of life instead of trying to make it grander. Still a 9/10 but THEY kinda ruin it. Howly, if you're reading this, I can help. We can still have a setup for 3 games (and Interea), but it doesn't have to be THAT way. Like, I cried 6 times (I counted). SIX TIMES. Trust me, it works.


Well, if I interpreted this comment right, if you remove THEM from the ending, it takes away from not only the heartbreak that is the ending, but the probability that it even happens in the first place. The whole point is that Marco was being forced, even if it was for a greater good. He would've been happy not giving a damn about earth if it meant staying with Amicus. And moving THEM removes the whole payoff of the Cato incident, and the explanation for the entire story happening in the first place.

Actually, you're right. I decided to re-read some parts because I guess I didn't really understand properly but I think what happens is that Marco accepts it because he forms a genuine bond with Amicus. So THAT is worth doing so they can be together. The dialogue would suggest that anyway and the few small changes you get in the bad route kind of feel like they go against the overall plot of unity. And now that I think about it, yeah, THEY need to be there for the plot to work. So you're absolutely right and I think I just didn't connect things properly.


The happiest thing is that after playing this work, I learned that the team has plans to do 2 other works related to ADASTRA, which is so exciting and looking forward to it!It also fills my life with anticipation!
