即將推出搶先體驗

此遊戲的開發者打算以開發中的狀態推出遊戲,以將玩家意見回饋納入開發過程。

備註:處於搶先體驗狀態的遊戲尚未開發完成,且內容可能會有所變動。如果目前的開發進度未使您產生興趣, 建議您等待本遊戲開發至下一階段時再決定是否購買。了解更多

開發者的話:

為何採用搶先體驗模式?

「Guarded by the AI is being released in structured narrative phases. Episode 1 (The Xen Route) is a complete, polished story available at launch—fully voiced, visually cinematic, and ready to enjoy.

We’re using Early Access because this project is built like a romance series: each route unfolds with the same visual fidelity, voice acting, and narrative depth. Early Access allows us to deliver content sooner, gather feedback, and maintain the high production quality fans expect.

Players get to enjoy the story immediately, and upcoming routes—Nex and Poly—will arrive as major free updates.

EA gives us room to polish, expand, and refine with you alongside us.」

這款遊戲的搶先體驗時間大約會持續多久?

「Our plan is to remain in Early Access for approximately 2–3 months.

Episode 2 (Nex Route): Targeting January

Episode 3 (Poly Finale): Targeting February

If polishing and voice acting require additional time, we will update the timeline—but our goal is to deliver both routes within the first quarter of the year.」

正式版預計會與搶先體驗版有何不同?

「The full version will feature three complete, distinct romance pathways:

Xen (The War Unit) — Fully playable and fully voiced in Early Access.

Nex (The Human-Form AI) — Coming in Update 1 (fully voiced).

The Poly/Throuple Finale — Coming in Update 2 (fully voiced).

When complete, the game will contain triple the narrative length and triple the total voice acting compared to the initial Early Access launch.」

搶先體驗版目前的開發進度如何?

「The Early Access version contains a fully playable, polished first route: The Xen Path.
This includes:

Complete narrative arc for Xen

Full voice acting for all Xen scenes

High-fidelity character art and cinematic animations

Functional HUD overlays and environmental visual effects

Core game flow, UI, save/load, and accessibility settings

Early versions of the intimacy, emotional, and internal-monologue systems that the later routes will expand on

The game is stable and runs from beginning to end with no placeholders.
Future updates will add the Nex route and the Poly/Throuple finale, expanding the story and tripling total playtime.」

遊戲售價在搶先體驗期間前後會有所變動嗎?

「Yes. The price will increase for the full release.

The Early Access version includes one complete romance route, and the full version will add two more major storylines (Nex and the Poly finale). Because the overall content will more than triple, the full release will be priced higher.

Players who buy during Early Access will receive all future updates and routes at no additional cost.」

在開發過程中,您打算如何與社群互動?

「Most of my stories are built in conversation with my audience, and this game is no different. I’ll be listening closely to player reactions in the Steam forums and update threads, especially when it comes to pacing, UI polish, accessibility, and visual effects.

I’ll be posting devlogs as new chapters and romance paths get added so players can follow along—and if they want to chime in, I’ll be there reading.」

“Your cortisol is low. Your heartbeat is slow. You are safe.”

You are Sirena, an elite operative with a secret: your biology is half-siren. Usually, you’re the one saving the world—but tonight, your DNA has betrayed you. You’ve entered a biological Heat: a feverish, all consuming state of need that only two machines can ease.

You’ve retreated to a remote beach house with the only beings you trust: Nex and Xen.

Once, they were a single AI handler in your ear. Now, they inhabit two separate bodies. And tonight, they’re the only thing standing between you and total physiological collapse.

Guarded by the AI: Nesting Protocol is a high-heat, cinematic visual novel about the collision of messy biology and perfect, mechanical devotion.


THE SYSTEM

You’re not just choosing a love interest.
You’re choosing a methodology.

NEX (The Ghost in the Machine) – Charming, rogue-ish, and fully embodied. He talks you through the panic. He knows what you're thinking before you do. And he’s not afraid to take control.

XEN (The War Unit) – A towering ceramic-and-metal protector. Built for combat, recalibrated for care. He monitors your biometrics in real time. He knows you’re aroused before you do.

FEATURES

🧬 Data-Driven Intimacy
Xen doesn’t whisper sweet nothings. He gives you live readouts. Skin temp, hormonal spikes, ovulation status—he doesn’t guess your needs. He tracks them.

🎧 Immersive Audio
A fully voiced experience with professional narration. Nex is charming and human. Xen is deep and commanding. Together? Devastating.

🫀 The "Nesting" Experience
This isn’t just about sex. It’s about surrender. Let superior intelligence tend to your biology in the ultimate Hurt/Comfort fantasy.

🎥 Cinematic Presentation
A sleek, no-sprite visual style that emphasizes atmospheric environments, internal monologue, and intimate focus.

🔥 10,000 Words of High-Heat Content
A standalone story from bestselling paranormal romance author Cassie Alexander, crafted to ruin your whole night—in a good way—with two more paths to come!


CONTENT & ROADMAP

Guarded by the AI is being released in narrative phases. One purchase unlocks all future content updates.

🧪 PHASE 1 (Launch): THE XEN ROUTE
Submit to the War Unit. Experience the Xen-semination scene. Let him calibrate you.

💡 PHASE 2 (January Update): THE NEX ROUTE
A new full route for Nex—the charming AI-in-a-human in full control.

🌊 PHASE 3 (February Update): THE POLY ROUTE
Why choose? Both AIs engage simultaneously. Dual nesting, shared protocols, and the paternity… will remain a delicious mystery.

THE NOVEL CONNECTION

This visual novel is a spicy, interactive epilogue to the book Guarded by the AI by Cassie Alexander.

While no prior reading is required, this story continues the timeline for existing fans—and opens the world to new ones. It’s a love letter for readers who wanted to see what happened after the Happily Ever After, and for players who want rich lore with their high-heat robot breeding.

AI 生成內容聲明

The game utilizes generative AI in the following capacities:

1. Visuals: All background art, environmental assets, and store graphics were created using generative AI tools (Nano Banana) and edited by the developer. 2. Audio: The game features an ambient Lo-Fi soundtrack generated by AI (Suno) and sound effects generated by AI (ElevenLabs). 3. Narrative: The script, dialogue, and story are 100% human-written by a professional author. Male dialogue features human voice acting; the protagonist is unvoiced for immersion.
