Serenity - Game Systems Foundation

Serenity – Game Systems Foundation

You didn't get into game dev to build the same main menu for the fifth time.

But here you are. Again. Wiring up settings screens. Re-coding a save system. Fighting the audio mixer. Building a pause menu that talks to an input system that talks to a localization layer that breaks the moment a designer renames one key. Three months in, and you still haven't built your game — you've rebuilt the plumbing every studio rebuilds, badly, under deadline.

And when it finally "works"? It's a house of cards. One singleton reaches into another. A tiny change to the menu breaks the audio. Your designers can't touch anything without a programmer babysitting them. You know it's fragile. You ship it anyway, and you pay for it in every patch.

Serenity ends that.

Serenity is a production-grade game systems foundation built on Clean / Hexagonal Architecture — 45 modules, every one split into engine-agnostic Domain/Application logic and a Unity adapter layer, wired by a Service Locator and a signal-driven event bus. No spaghetti. No god-objects. Change one system without detonating the other five.

Stop rebuilding. Start shipping.

Out of the box you get the systems every game needs and every project reinvents:

• UI that scales — menus, modals, cascade (drill-down) menus, a flexbox composite-view system, a Theme Builder wizard that generates full themes from scratch, 8 themes, and a live preview window (wireframe and themed render, at any resolution) so you see the screen before you press Play.
• A data-driven HUD with a visual builder — health bars, ammo counters, timers and any live stat, authored as data: nine screen anchors, seven display styles, automatic player-2 mirroring, and fifteen ready-made animation presets that fire on value changes or signals. Drag, scale and rotate elements in a true editing preview — every gesture a single undo step.
• Achievements — declarative unlock conditions, progress tracking, unlock screenshots captured in the background, a themeable achievements screen, a toast on every unlock, and storefront mirroring through a Steam gateway validated against the real Steamworks SDK (Xbox, Epic and PlayStation gateway templates included).
• Leaderboards — a five-step wizard builds the whole stack: pick a preset, pick the score your game already tracks, pick where the data lives — device storage, JSON files, embedded SQLite, your own HTTP service, or a direct Postgres/MySQL/MongoDB connection — and get a themed, ready-to-navigate leaderboard screen. Deterministic ranking, proper tie handling, and a misconfigured backend falls back instead of breaking your game.
• Game saves & permanent progress — configurable save slots, each an extensible document of typed sections; slot menus list label, timestamp and completion without loading whole saves; checkpoint quicksaves ride the active slot; and permanent progress (completion counts, unlocked extras) survives slot deletion. Cloud saves are a backend choice, not extra code.
• Complete audio — player, music with loop-points/BPM/tail-fade, a routed mixer, 3D/positional audio, and batch import. Audition clips without entering Play mode.
• Game-feel that AAA studios charge for — a full Feedback system: gamepad vibration, DualSense LED + adaptive triggers, screen shake, hit-stop and screen flash — driving DualSense, DualShock 4 and Switch Pro over USB and Bluetooth, on Windows and Linux. Now with gyro (motion) support on all three pads, drift calibration included. The stuff that takes weeks of HID reverse-engineering. Done.
• Settings & input — a stepped Settings Wizard, full Input System integration with per-player rebinding for local multiplayer, and player-facing Gyro Aim & Sensitivity options out of the box.
• Localization, cutscenes & gameplay — Unity Localization with a missing-key validator, a Cutscene Wizard with Timeline support, plus gameplay modules (waves, stages, characters, spawners, score, combo, checkpoints) you compose instead of code.
• Zero to playable in minutes — the Serenity Hub is the package's front door, rebuilt as a full workspace: favorites, recents, and Ctrl+K search across all 89 tools. The Setup Assistant scaffolds a full boot → menu → gameplay → pause loop in a 5-step wizard, and Validate Everything aggregates every project validator into one report with one-click fixes.

Your designers will finally stop waiting on you.

Build whole UI screens, author menus and modals, design animated HUDs, wire signals to reactions, trigger feedback and cutscenes, import audio in bulk — all in the Inspector, zero C#. Signal Reaction binders. Health-check dashboards. Broken-reference reports. A visual Signal Flow diagram showing every signal's dispatcher and reactions. An Animation Hub that finds, edits and live-previews every animation in the project on the actual model. Safe Asset Delete, which warns you before deleting a ScriptableObject something else still references. The no-code surface real teams actually need.

Built for the AI era.

Serenity ships a declarative recipe system: author your entire project as human-readable .serenity-recipe.json and let an AI agent generate validated, idempotent, reversible ScriptableObjects through the Editor API — no hand-written .asset files, no corrupted GUIDs.

Headless validation and discovery dumps let an agent confirm the project is wired correctly and self-correct. And the new AI Prompt Builder interviews you about what you want to build and generates the optimal prompt for your agent — grounded in your project's real assets, delivered to the clipboard, a file, or straight into your agent.

Built from the ground up for the AI era — so you can direct an agent to assemble your project, not just autocomplete snippets.

Trust it, because it's tested.

Over 14,000 automated tests (5,160 EditMode + 8,982 PlayMode), plus a standalone 6,200+ test suite that runs the entire Domain/Application layer in seconds without launching Unity — the concrete proof that the architecture is engine-agnostic. AI-facing documentation for all 45 modules — every system documented end-to-end, nothing left to guess.

You can keep rebuilding the plumbing. Or you can install Serenity and build your game.
