Unity teams up with Google to launch Spark: multiple AI Agents collaborate to develop games, with direct access to professional assets.

Beating AI News Flash: Unity and Google jointly unveil a new AI game development tool, Unity Spark, with a closed beta planned for later this year. Spark is based on the Unity game engine, allowing users to create and edit 3D games directly in the browser without installing traditional development software. It supports natural language commands while also retaining manual editing capabilities.

Spark allows multiple people to edit the same game project simultaneously, and multiple AI Agents can also work in parallel. Users can have Agents build scenes, adjust lighting, or modify game content. It is also integrated with the Unity Asset Store and can recommend assets created by professional creators based on user requests. For example, if a user asks to add a cape to a character, the AI can find suitable resources from the store.

Spark will also use multiple generative AI models and does not rely entirely on Google technology. Unity CEO Matt Bromberg emphasized that the team does not want users to generate a complete game with just one command, but rather to let creators repeatedly revise and polish their work. Users can use AI to accelerate development while continuing to use professional art assets and traditional editing tools.

However, Spark still has notable limitations at launch. The editor only supports desktop browsers, and completed games can run in desktop and mobile browsers and be published to Google Playground. But projects cannot currently be downloaded, exported to the full Unity editor, or sold. The platform plans to charge credits based on AI usage, with specific pricing not yet announced.
