Arvale Protocol
A downloadable game for Windows
Home to around 8.5 billion citizens, Arvale City has become the number one living spot for the entirety of the world's population. Surrounding the city, are the walls that shield people away from the outside world. Each and every citizen have been chipped at birth, all of which being special devices handcrafted by a high-rise corporation, otherwise known as "A.V.A." These devices are called, "B.D's." While having a super computer implanted into your brain might seem like a cool idea, having a government tracking device will prove to be a lot more problematic than one might think.
You play as Zeno. After a deal goes wrong, and you awaken inside an underground complex, you will quickly realize that not everything is as it seems. On the surface level, a military-grade virus has been uploaded into everyone's B.D, turning the citizens of Arvale into sex crazed lunatics. Join up with three other party members, and embark on an adventure to uncover the dark secret behind the three main factions.
Arvale Protocol features traditional RPGM combat, with a hint of sexual tension to lighten up the mood. Throughout your journey, you will encounter many different characters and events. Ultimately, it will be up to you as to how you will approach each and every scenario.
-Various H-Content for each character.
-Thrilling story with many twists and turns!
-The ability to romance and choose a path for the character of your choice!
...as well as much more!
Arvale Protocol features all different types of content:
-4 complete districts / zones / regions, all with their own distinct stories, quests, characters, boss battles, and content.
-Unique romance options for each corresponding party member.
-Varied H-Scenes across many different characters and enemies.
-Special CG animations for all sexual abilities.
-15-28 hour main quest storyline.
-Various side quests among the different districts.
Arvale Protocol will be a free title at launch (whenever that is), so if you'd rather wait for the full product, then come back later!
If you want to help suggest / personally request content for the game and get involved with development, then come on by and support me! I'd greatly appreciate it! I try to make all of my games free.

To preface this comment, I will admit I very much enjoyed the game. I appreciate the art and story.
Now, I will myself admit I am not one for feet or shrinkage, and such components of the game do not interest me at all. Now the other parts? Those I am fine with.
The combat was difficult, but pretty fun, and from my understanding well scaled to what you encounter. The scenes I did want to look at were hot. So thats a plus.
My main pain is that damn pizza quest. I spent several hours looking for them in the same sections over every crack and counldnt find the final ones, even indoors.
The intro and personality of the characters does tie in well with their dialogue. Im not too sure how many people actually closely read dialogue to try to pick out characterisation from it so lmao.
Thanks! I try to balance the content here and there to make sure everything gets a chance. It's also one of the reasons why I introduced safehouse characters. I wanted a variety of content. Currently, I've been focused on trying to get a lot more non feet content in the game to further showcase the effects of the protocol.
The pizza quest can be a little annoying. They're mostly outside, with a few exceptions. The most easily miss able ones are: the one in the apartment next door to the safehouse, the one in a house in the Housing Block, and the one at The Arena Guild.
As for the personality of the characters, I actually get a lot of people saying that's one of the game's biggest strengths! Personally, I wasn't expecting much to care, but I always appreciate it when people notice.
What has been added since 0.6.1???
If you start New Game Plus, you can play through the prologue of Route B. There's also special unlockable characters only available in New Game Plus. 0.8.0 is coming soon, and it will be big.
ok fire! Just a question... Sorry for always asking about giantess stuff, but was more of that added at all?
No, it was more or less to lay the foundation for next update, which will have quite a bit of it.
okay
Great game! Appreciate the fact that you put a lot of effort into quests and the story, not just H-scenes
I have a couple of quest-related questions:
1. I'm already in the Outskirts, but still haven't been able to progress "Down with Desperation" (Joy's quest). Could you give me a little tip on where I can find her? I think I've already been everywhere in the Party District, although there's a door with a bunch of bouncers who won't let me in
2. I'm also stuck on the "Workaholic" quest because I'm unable to get through the ant labyrinth under Athena's house. Am I missing something?
On a side note, Industrial District contains A LOT of locked doors without any apparent means of entry. Will they become available later in the story?
Hey there! Thanks!
Joy can be found right outside your apartment. As for the ant maze, the exit is at the very top. Also, for the locked doors in the Industrial District, it depends on which doors. There's one building that's next to the factory that is inaccessible. I sometimes put certain locked doors in areas I might return to give a side quest. A.V.A doors are only unlocked by meeting a certain character in New Game Plus. Any other locked doors should have a quest connected to it.
Only took a quick peak into the game and was positively surprised by the quality. Good stuff! I think I'll play this some more. Even though RPG Maker games typically don't interest me as much.
You might want to take a look into polishing the beginning though. The plants in the room where Zeno wakes don't have collision, I spotted multiple spelling errors and I would appreciate some indication whether you can walk off screen or not. A different texture on the ground for example. Pokémon did it by placing rugs on every house exit.
Usually I wouldn't bother pointing those things out, but seeing as well rounded most of the game is, those flaws just stand out to me.
The early game needs a bit of a rework. Once you get to the mid game, I start using shadows to indicate passage ways. I just haven't gone back to add them. I'm usually on top of spelling mistakes, but since it's such a big game, I'll probably forget some areas.
When you do get to the shrinking part in the base game
The quest "Zinc in the Hole" is where the first bit of it starts. There's size content sprinkled all throughout the game after that.
Okay thanks, sorry to be a bother but how far along do I have to play to get there? I don’t wanna spoil anyone so is there somewhere I can message you? Do you have a discord server for your game?
I don't have a discord server sadly. Zinc in the Hole begins right after to complete the prologue (you'll know when you see the title card). The quest takes you to the next district. You'll have to get through that entire quest which includes two boss fights. Once you get to Zinc H.Q, you'll meet a specific character towards the end of the quest. From there on, it's pretty self explanatory.
She's a pretty tough boss, so you'll have to be ready. All together, it might take around 2 hours. The game itself takes around 15-20 hours to complete, so while it won't take ages to get there, it might take you a bit.
Eleanor's Dilemma, which is the side story you select on the main menu also features all size content, but it's rather short.
Okay, thank you.
Any way you can implement more size stuff like crushing or even accidental crushing in the main story?
It's not the main focus, but I do have one more shrinking section planned, so I could consider it when I start brainstorming the scenes for it.
Is the original game have any gts content, or it's only in sidestory?
The orignal game has a few gts sections. Fort Venus as well as a few other characters in some side quests. Size content doesn't appear until you get to the quest, "Zinc in the Hole".
Combat system is so hard, but it's pretty nice game :] keep going!!
I've played until the moment where I'm supposed to go to the Industrial District for now, and dang, do I love this game! I love the main group, and the setting of the world... Of course as a foot fetishist, Risa takes the cake for me! But the best H-scene for me is probably Eden's footjob... It does remind me of Mariel's scene from MGQ, and boy do I love that scene... I don't know if animations are planned for H-scenes in the game, but if I had to see one animated, it would be this one! Hope to see a lot more footjobs in the future!
Thanks for this game, I will be following it with a lot of interest!
Thanks for the kind words! She's actually inspired by her, funny enough. You were the first person to point that out.
I will not complain about Mariel inspired characters, since Mariel is one of my favourite characters in H-games, so Eden is already one of my favourite for this game too. Can't wait to see more of her! For that matter, I do like the 3 Valkyries, I have a weak spot for angels... If it were me, I'd like for all 3 to give footjobs :p
Also I was wondering if more monster girls were planned for the game? Asking for a friend, of course...
It's not really a big main focus. I hinted at some sort of cat girl character with Eleanor's experiments, but other than that, most characters are either humans or angels.
I see. Thanks for answering. I did indeed see a catgirl being experimented on in Fort Venus... So maybe it's gonna be her? Can't wait to see~
Will there be impreg?
As a gameplay mechanic, probably not.
I've thought about making it some sort of ending though if you go at it with a party member too much.
That sounds amazing!
Will there be futa?
Eu espero que o autor do jogo consiga traduzir esse post
Bem eu zerei a demo então a nota em geral que dou pro jogo e um 6.9/10.
como ainda esta em desenvolvimento eu não vou dar um 6 mais ao mesmo tempo poderia ser muito melhor mais minha analise mais detalhada fica em baixo:
Pontos positivos:
As personagens são legais, cada uma tem a sua personalidade e objetivos diferente, e se o deve cumprir a promessa de cada uma ter uma opção de romance melhor ainda. (a que eu mais gostei foi a Cecilia, queria que tivesse uma opção no jogo de deixar ela cada vez mais "descontrolada na luxuria" ou que quanto mais o player interage-se com ela, mais ela iria se "soltando")
Gostei do ambiente do distrito, bem detalhado e rico
Gostei também das missões bem diversas
E da historia que e interessante
Pontos negativos:
Os encontros com inimigos são aleatórios, o que e insuportavelmente chato, seria legal se eles fossem posicionados
As cenas H, por mais que eu entenda que ainda esta na demo não são interessantes, e um ponto que precisa melhorar
Uma questão que eu queria que o dev fala-se e a questão do "caos da cidade", e algo que os personagens falam e que o jogo fala, mais que não e transmitido pro jogador, a situação do distrito onde a demo se passa esta longe de ser caótico, agora eu não sei se nos outros distritos terão uma situação pior mais ai outro ponto
Coisas que eu queria que tivesse
Os infectados... eu queria que tivesse mais deles e que se o player fosse derrotado tivesse uma cutscene dele sendo "infectado", além de poder ver os outros infectados em cenas H
Eu também gostaria de desse de alguma forma ir infectando o protagonista com o vírus e isso de alguma forma se transmitisse em habilidades ou nas futuras opções de romance
A opção de Ctrl pra pular os diálogos rápidos
Gostaria que tivesse um server no discord para poder discutir mais detalhadamente com o desenvolvedor........
Appreciate the feedback! We'll be looking into expanding the world, and making it feel a lot more alive. That's one thing I really want to focus on for the next area, especially since it's on lockdown. I'll probably end up adding some random events that occur on the streets, just to spice things up a bit.
As for H-Scenes, one of my main goals is to fix them up a bit, and make them feel unique and interesting. As the game stands now, they're a little lackluster in my opinion, and can definitely be done better. A lot of the earlier H-Scenes are first on my list, since they were made pretty early on in development
Also, a skip / fast forward button is planned to be added in the next update.
