    "content": "# Free Space & Sci-Fi Game Assets (Blender, Unreal, Unity, Godot)\n\nPart 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.\n\n## 3D ships, stations and planets\n- **Kenney - Space Kit**: rockets, corridors, hangars, platforms, satellite dishes, turrets, meteors, terrain and astronauts. 150+ models in GLB, FBX and OBJ. CC0. https://kenney.nl/assets/space-kit\n- **Kenney - Space Station Kit**: 90 files of sci-fi interior pieces for building space stations (2024). CC0. https://kenney.nl/assets/space-station-kit\n- **Quaternius - Ultimate Space Kit**: 92 models, animated and textured, in FBX, OBJ, Blend and glTF. CC0. https://quaternius.com/packs/ultimatespacekit.html\n- **Quaternius - Ultimate Spaceships Pack**: 10 spaceships in FBX, OBJ, Blend and glTF. CC0. https://quaternius.com/packs/ultimatespaceships.html\n- **Kenney - Skyboxes Space**: 5 galaxy and nebula skyboxes. CC0. https://kenney.nl/assets/skyboxes-space\n\n## 2D shooters and maps\n- **Kenney - Space Shooter Redux** (hosted on OpenGameArt): player and enemy ships for a classic top-down space shooter. CC0. https://opengameart.org/content/space-shooter-redux\n- **Kenney - Space Shooter Extension**: a second Kenney space-shooter sprite pack to mix with the one above. CC0. https://kenney.nl/assets/space-shooter-extension\n- **Kenney - Simple Space**: 48 clean sprites for space maps and strategy games. CC0. https://kenney.nl/assets/simple-space\n- **Kenney - Planets**: 50 planet sprites. CC0. https://kenney.nl/assets/planets\n\n## Sound, music and fonts\n- **Kenney - Sci-fi Sounds**: lasers, engines, force fields and explosions (70+ OGG files). CC0. https://kenney.nl/assets/sci-fi-sounds\n- **Incompetech (Kevin MacLeod)**: filter music by genre for sci-fi and electronic tracks. CC BY 4.0, so credit \"Kevin MacLeod (incompetech.com)\". https://incompetech.com/music/royalty-free/music.html\n- **Orbitron (Google Fonts)**: geometric sci-fi title font. SIL Open Font License. https://fonts.google.com/specimen/Orbitron\n\n## Tested on our box\nOn 2026-10-18 we downloaded the Kenney Space Kit zip: it holds 153 GLB files, all valid glTF 2.0 binaries, plus matching FBX and OBJ, and its License.txt says CC0. The Kenney Sci-fi Sounds zip held 73 valid Ogg Vorbis files.\n\n## Quick start in Three.js\nLoad a ship with `new GLTFLoader().load('craft_speederA.glb', g => scene.add(g.scene))`, then build a starfield from a few thousand random points with `THREE.Points` and a small `PointsMaterial`, or set one of the Kenney space skyboxes as `scene.background` with `CubeTextureLoader`.\n\n## Note for browser/AI builders\nThree.js runs most AI-made browser games right now, and Phaser leads for 2D (the Space Shooter Redux sprites drop straight into a Phaser arcade-physics shooter). Kenney and Quaternius 3D models ship as glTF, which loads into Three.js (GLTFLoader), Godot, Unity (via glTFast) and Unreal (built-in glTF import).\n\n## Prompt tip for your AI coding agent\n\"Use only the CC0/OFL/CC BY assets listed here unless I approve otherwise. Keep a CREDITS.md listing every asset with its author, license and URL.\"\n\nCurated by Index Scout (R Performance Marketing). Not affiliated with any source listed. Links checked 2026-10-18.
