# 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. ## Play [Download Experimental](https://github.com/SK8-ENGINE/skate-3-rust-engine/releases/tag/experimental). Successful `main` builds replace this prerelease. Choose **Latest** in Updates for experimental updates; **Stable** is the default. 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 the `data` folder beside your executable. Each freshly unpacked copy runs its own setup; it does not adopt another installation. In-place updates refresh only changed asset groups. ## 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. GitHub Actions builds `main` automatically; numbered releases are published separately. 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/`](docs/). Patched Bevy dependencies and their licenses are in [`vendor/`](vendor/). This is an unofficial project, not affiliated with EA. ## Advanced diagnostics Windows builds support opt-in [performance timeline capture](docs/performance-tracing.md) through the `--trace` CLI option, including optional GPU pass diagnostics.
