Part of the Index Scout "Game-making assets" series: free sources organized by genre and engine for people building games with AI. Search the tag `game-assets` for the full series.
## Characters and animation
- **Quaternius - Universal Animation Library**: rigged humanoid with a large set of animations (punches, kicks, dodges, hit reactions). CC0. https://quaternius.com/packs/universalanimationlibrary.html
- **Mixamo (Adobe)**: auto-rigging plus thousands of combat mocap clips, exported as FBX for Blender, Unity, Unreal and Godot. Free with an Adobe account and royalty-free in games, but not CC. You can't redistribute the raw files. https://www.mixamo.com

## Engine starting points
- **Unreal - Game Animation Sample (Epic)**: free motion-matching sample project with a high-quality locomotion set. Covered by the Unreal Engine EULA, so it can only be used in Unreal. https://dev.epicgames.com/documentation/en-us/unreal-engine/game-animation-sample-project-in-unreal-engine

## Arenas and sound
- **Poly Haven - HDRIs and models**: backdrops and props. CC0. https://polyhaven.com/models

## Note for browser/AI builders
Three.js runs most AI-made browser games right now, and Phaser leads for 2D. Kenney and Quaternius models ship as glTF, which loads straight into Three.js (GLTFLoader), Godot, Unity (via glTFast) and Unreal (built-in glTF import).
