Powder Line, a Fusionery-built snowboarding game, running in the browser — "a snowboard season on one mountain — four runs, rival riders, and a career to build"

Gameplay

Every one of these started as a sentence.

Describe a game and Fusionery builds it — a full Godot engine world running in your browser, with real combat, racing, survival, and multiplayer. No installs, no launchers. Here's one you can play right now.

The editor

Describe a game. Then shape every detail.

Fusionery Studio turns a prompt into a complete, playable world — then hands you a full desktop-class editor to make it yours. Everything below runs in the browser.

The Fusionery Studio editor: a rendered 3D world with menubar, inspector, and the AI agent dock — The studio: your game rendering live in the center, feature menus above, the AI agent alongside.

Create by conversation

Tell the agent what you want — "a snowy survival game with wolves and crafting" — and it plans the world, enemies, goals, and pacing, then builds a playable version in minutes.

Edit the world directly

Click any object in the rendered game to move, rotate, restyle, or delete it. Drag buildings, repaint props in the built-in 3D asset studio, and insert new models from a searchable library.

Direct the whole arc

A timeline sequencer lays out acts, encounters, cutscenes, and music. Add triggers, gate progression, and play from any point to test exactly the moment you changed.

Cast and characters

Rigged, animated heroes and enemy families ship in the box — or generate brand-new characters from a text description and watch them walk into your game.

Instant test play

Flip the stage from edit to play in place. Spawn at the camera, tweak, flip back — the loop between "change" and "feel it" is seconds, not builds.

Publish to players

One click validates, builds, and publishes to Fusion Castle with lobbies, ready-up screens, and hosted multiplayer where the game calls for it.

Composable game cycles

Start with the play loop. Then bend it.

Every Fusionery game runs on a game cycle — acts, encounters, cutscenes, and music laid out on one timeline the engine actually follows. Racing, shooters, survival, RPGs, tower defense: the same loop composes across genres, and it's yours to change.

Act I · First Light ⚔ Scout wave ⛏ Gather & craft ♪ Calm theme 🔒 Gate: forge the spear Act II · Nightfall 🎬 Cutscene ⚔ Siege ×2 ♪ Combat mix ⚔ Boss 🏁 Finale

Change it with a sentence

"make act two a midnight siege — two waves, then the boss, and darker music"

The agent rewrites the cycle to match: encounters rescheduled, goals rewired, the music director cued — and the whole game rebuilds around the new arc.

Or shape it by hand

The sequencer puts every beat on a timeline in the editor. Drag encounters between acts, insert cutscenes and triggers, crop music to the moment — then play from any beat to feel exactly the part you changed.

Beyond desktop control

Don’t ask an agent to improvise a production pipeline.

Desktop agents are excellent collaborators for bespoke local work: they can move between files, tools, and applications. Fusionery is better when the result needs to become a coherent, playable game with a durable source of truth—not just a set of changed files.

Raw desktop control

Flexible, but you own the glue.

Directly operates the local editor, files, plugins, and command line.
Depends on your project conventions, installed tools, and manual review.
Can make a useful local change without proving the game still builds, plays, or releases safely.

Fusionery

A managed contract for making games.

Agents operate bounded game concepts—systems, worlds, assets, builds, and releases—not arbitrary pixels and files.
Every revision becomes a versioned, inspectable blueprint with capability checks, history, and undo.
Preview builds, release readiness, workspace access, metering, and cross-platform delivery stay in the same production path.

The strongest workflow can use both: connect Claude Desktop or another MCP client to Fusionery, then let the agent use a game-aware platform surface instead of reconstructing your workflow from a local desktop. Claude Desktop supports MCP connections.
