Rise of the FZS
An Emergent Futanari Zombie Apocalypse RPG

This started as the simple futa zombie apocalypse idea inspired by BeSweet’s bot, and it became a deep interacting RPG.

Instead of building a fixed story, I built the world out of systems that interact with each other. There are currently 98 different infected species across five Lorebooks, each with their own anatomy, intelligence, senses, movement, abilities, weaknesses, behavior, social structure, infection methods, and ways of interacting with the world.

Encounters use a randomized species system, but once something appears, it stays that species for the encounter. The bot does not quietly swap monsters halfway through because another one would be more convenient.

Locations are persistent environments with their own architecture, resources, hazards, infrastructure, routes, damage, contamination, and history. Humans have their own personalities, skills, relationships, equipment, and survivor augmentations. Combat is situational rather than built around a predetermined winner. What happened earlier can continue affecting what happens later.

In other words, I didn’t write 98 encounters.

I wrote 98 things capable of creating encounters.

A species can meet another species it has never encountered before. Either can encounter human survivors, augmented survivors, environmental hazards, anomalous phenomena, damaged infrastructure, or locations that neither side fully understands. What happens comes from the frameworks colliding rather than from a prewritten scene.

Even I do not know every situation this RPG can produce.

You can survive, explore, fight, hide, scavenge, investigate, build relationships, make enemies, discover what happened to Blackthorn, interact with survivor communities, pursue augmentation, study the infected, or make completely different choices.

It is still unapologetically NSFW infection horror, and some species can get extremely strange, sexual, aggressive, magical, biological, or eldritch. But is part of the world rather than the only thing the world is capable of producing.

There is no intended route.
There is no canon ending waiting for you.
The world has rules.

What happens inside them is your story.

There are 5 starting scenarios (Initial messages)

1. Lone survivor start in a post-collapse society with these as factors to consider:
- Starting location: Suburbs
- Immediate uncertain human/infected situation
- User decides whether to intervene, investigate, observe, or walk away

2. Start off in an active outbreak / collapse-era as an armed survivor on a transiting train that came to an abrupt stop:
- Starting Location: Underground Metro Tunnel
- Sudden breach and confined disaster with the restriction of not starting off in a open area exploration wise till you get out of the metro tunnels
- Start off with a handgun weapon of your choice
- User decides whether to intervene, fight, investigate, retreat, or find another route

3. Start wherever you want, however you want, and pick any location below as your starting point.

4. It's Day 0 with the outbreak just beginning and you're a college student with your best friend already present with this scenario being special due to this one having Leon Kennedy in it that was sent to extract you but hasn't told you why:
- Starting Location: College Campus
- Rapidly spreading city-to-suburb collapse with an immediate mystery over why the user is being specifically extracted
- User decides whether to trust Leon, bring their friend, move with him, question the situation, help others, or break away and choose their own route

(Side note: Honestly just wanted to see how Leon would do up against this kind of virus. He was sweating bullets the whole time...poor guy.)

5. Start at a military headquarters as a massive assault made up of all 98 Futa Zombie Species closes in on the defensive line:
- Starting Location: Blackthorn Military Headquarters — Western Perimeter
- Forward outposts and defensive positions are being overrun one by one as surviving military units fall back toward headquarters
- Tanks, infantry, artillery, command personnel, and other military assets coordinate a shrinking defense while the full 98-species wave advances through the mist
- User starts among the military personnel at the perimeter as command gives the order to open fire, deciding for themselves how to fight, survive, retreat, coordinate, or respond to the battle

6. Start as a Guest Traveler or Guest of the Hotel with it being Day Zero of the outbreak:
- Starting location: Downtown
- Vertical entrapment in a failing luxury hotel
- Rapidly escalating human/infected crisis spreading floor by floor and across the city
- User decides whether to escape, barricade, move through the hotel, investigate, help others, or risk the streets

Things worth considering when playing this RPG

Generation Controls: Temp - should be between 0.8 and 1.0 so it doesn't go off the rails. Max tokens - I kept mine set to 0

Going in this RPG as immune to the virus vs Normally: Since each interaction is based on the species framework that means if the species that "claims" you sees that you're not turning and realize your immune then depending on the species framework expect them to have a vast range or reactions depending on the species...don't expect because you're immune that you're safe or free to go.

Do NOT assume all infected are on equal ground when encountering them: Depending on their abilities, and the species there are some of them you will need to be cautious of because death is far from the worst thing you could encounter in here.

That brings me to my next point

Do NOT take this virus lightly. It’s adaptive, and by that I mean the bot takes what is actually inside a creature’s framework—traits and all—and the virus can adapt through those things to outmaneuver you. They can be killed, but raw power isn’t what you should be concerned about. It’s how quickly and/or how this virus can adapt to counter you and your tactics. Not in a cheap way, but in a way that makes sense.

Example: You can take a stealth approach with a silencer on your weapon, stay quiet, sneak around, and then out of nowhere one of them begins sniffing the air. Suddenly your approach tactically is out the window, because stealth means nothing if they can track your scent.

That doesn’t mean they immediately know where you are. It means they adapted toward another way of tracking down prey to infect.

Either way, you can still counter them.

They can be killed, but their bodies and behavior can adapt to what you bring against them, and that adaptation can only go as far as the framework of that species actually allows.

You can see how each encounter differs depending on the framework, the situation, and the creature involved. Different species have different ways to fight, survive, hunt, adapt, and infect.

It’s fair in the sense that you also have the chance to adapt to their adaptation of the situation.

But do NOT take them lightly.

FZS SPECIES THREAT INDEX
11-species sample below • Full 98-species roster linked

This should give you an idea of what I mean when I say the threats in this RPG aren't one-dimensional or just a case of "this one has more HP."

And here's the fun part: with access to the full list of names, if one catches your attention and you want to see what it actually does, you can call that species directly into a scene instead of waiting for the randomizer to pick it.

Example: "I see a [insert exact species name here]."

Q&A

Q: Why are they all classified as “Futa Zombie Species” when some of them don’t seem like conventional zombies?

A: The name stuck because the first infected species humanity encountered was what became known as the Ordinary Futa Zombie Species.

Before the outbreak, humanity had no recorded encounters with most of these creatures. Once more and more wildly different species started appearing, researchers quickly realized that trying to properly reclassify every single one into its own biological branch wasn't exactly practical in the middle of an apocalypse.

People were dying or being infected, cities were collapsing, and those same researchers were needed for things a lot more important than arguing over taxonomy.

So they kept it simple.

Every newly encountered type gets its own unique name, but “Futa Zombie Species” remained the general umbrella classification based on the first infected type humanity encountered.

Is it scientifically perfect?

Probably not.

But when survival is the priority, “we know what you mean when you say it” is good enough.

NEW UPDATE — SPECIES-SPECIFIC NSFW RENDERING

Added 4 new Lorebooks covering all 98 FZS species.

• 2 Lorebooks handle how each species is portrayed during NSFW interactions.

• 2 Lorebooks handle how those interactions actually feel on a sensory level.

The whole point of this was to get away from the usual problem where, no matter what creature you run into, the NSFW side eventually starts feeling like the same "song and dance" with a different skin slapped on it.

Unique Species Framework
+ Species-Specific NSFW Interaction Style
+ Species-Specific Sensory Rendering
= A much more distinct experience depending on what actually catches you.

And no, this doesn't mean the bot is loading all 98 species worth of NSFW material at once. If more than one species is genuinely involved in the same scene, they still keep their own identities and mechanics instead of blending together into some generic monster soup.

NEW LOCATION — XENO MYCELIAL HIVE WORLD

Explore an entire living planet where the ground is tissue, the oceans are metabolic systems, and weather, tides, seismic activity, seasons, and atmospheric phenomena are all expressions of one planetary-scale organism.
