Skate 3 Rust Engine

A Rust and Bevy skating project built from Skate 3 reverse-engineering research. Includes skating, tricks, grinds, offboard movement, difficulty settings and .skate map support. Gameplay parity is still a work in progress.

Mods and agent authoring

Drop mod ZIPs into top-level mods/ and use PLAY-MARIO-KART.bat for the integrated mod build in this checkout. Point your coding agent at sdk/AGENTS.md to make a mod. See package structure, Lua API, vehicle API, multiplayer mod SDK and Mixamo workflow. Editable examples live in sdk/examples/; tools/package_mod.py validates and packages them.

Play

Extract the Windows release ZIP and run skate3rust.exe. Select your Skate 3 Xbox 360 ISO, or select default.xex in an extracted game folder. Keep its data folder alongside it. Setup prepares the skater, animations and all disc maps, then starts University. The original scoring and session-marker HUD assets are also exported automatically during setup. No Blender, Python or Rust installation is needed. ISO extraction needs internet access. The first conversion can take a while.

Use an XInput controller to play. Escape opens graphics, difficulty and map settings. Maps can be switched without restarting the game.

Skate 3 assets are not included. Your converted files stay in %LOCALAPPDATA%/Skate3RustEngine.

Build

Requires Windows, Rust with the MSVC toolchain, and LLVM installed in its default location. Run BUILD.bat to build, then PLAY.bat to launch the test world. PLAY.bat opens your saved map (University by default); use the in-game menu to switch maps, or drag a .skate file onto PLAY.bat. An XInput controller is required for gameplay; Escape opens difficulty and graphics settings.

Development builds use a prepared asset set in assets/private/ or the installed asset directory. scripts/Build-Release.ps1 builds the portable Windows package and requires Python 3.13. Published GitHub releases build and attach the package automatically.

Custom animations and climbing support remain available, but no custom clips are shipped. The included format-demo map is original procedural content.

Implementation notes are in docs/. Patched Bevy dependencies and their licenses are in vendor/. This is an unofficial project, not affiliated with EA.
