Etlina's Principle
A downloadable game for Windows, macOS, and Linux
Three years ago, humanity discovered a new type of living organism - a symbiotic life form called "Nox Limax". In the wild, it helped the few deep caves animals to survive in extreme conditions, using them as a host. Increased physical abilities, regeneration, gaining new unique features of other species - and this is far from the limit of It's potential.
But, one year after the successful tests, something happened that seriously changed the world.
At some point, people began to turn into slimy latex-like creatures. People, animals, flora, and even the environment - everything was devoured on the Nox's path. Whatever was deemed a threat was killed. The environment of the city and it’s neighborhood, animals, and fauna - all changed drastically, turned into a very dangerous place, like an alien planet with its flora and fauna. Tho, there were also those who were able to resist these symbiotes mentally, saving their identity and, mostly, human form. Rejected by humans and monsters, they are living in isolated territory by their own, place, which has now become a home for many - mad fanatics, shady businessman, mercenaries, and scientists.
You are the member of the HOWL Squad - special military units designed to perform tasks in conditions of increased danger. On your way you will meet many local inhabitants, most of whom may not be as horrible as they are told to be.
On your way you will find a lot of enemies and friends, and at the end decide who is the the real threat for your existence.

There is a show in the game he is watching similar to the Anime "Gate" In it. Is this a real AVN one made up just for the game or one in the works when you complete this one?
I made this render a long time ago, about five years back, right after I finished watching the anime. It really is a reference to Gate, and I have some ideas regarding the next project, which will be related to fantasy. But there won't be any concept of summoned heroes or modern technology in it.
You talked up how 0.5 would have some sex scenes, yet all I got was a few renders of a short BJ from Melisa? Am I missing something? You said there's two Melisa sex scenes??
If I remember correctly, I was talking about two sex scenes with Melissa and Sienna (one scene with each).
Ohhh okay, gotchya. I misunderstood. Also, I absolutely love this game, out of hundreds of AVN's i've played, this is in my top 3 in terms of story. That said, I really hope you work on the sex scenes a bit. They need some work. I'm fine with them not being animated, but if they're going to be only static renders then they need to be really good. Right now, the scenes seem to have only like 2-5 diff renders, and they're not very good. An example of an AVN that has great non-animated sex scenes is "Origin Story" if you want some inspiration. Anyways, good luck with your work. Can't wait for the next update.
PS. I love Sparkle, I really hope she's a LI and we get to see a lot more of her
Huge potential here. Beautiful renders, and a very interesting story. Unfortunetly there's not much lewd content. You gotta speed up the relationship building a bit, as amazing as the story is, there's been a little too much focus on it, while ignoring everything else. Still, im loving the game so far, in terms of story, this is probably my top 3 AVN's
<3
I personally think this avn has one of the best world and story of any other avn. The render are pretty good too! I can't wait for more updates :D
Really cool world, lots of latex stuff
Привет когда новая версия будет?
Some of the best renders on the site and a very interesting story, definitely worth playing
This is without a doubt, one of the most fascinating stories I have ever found... anywhere (I have about 800). I am pretty good at anticipating the story in nearly any game but this one... lets just say it is uniquely unpredictable, in a great way.
