Getting started

Windows and Linux

Unzip, point it at your disc image, play.

  1. Download the release zip for your system from the Downloads page and unzip it anywhere.
  2. Start the game: halo.exe on Windows, ./halo on Linux.
  3. Pick your disc image in the file picker. If you'd rather skip the picker, put the .iso or .xiso next to the executable and the game will find it.
  4. The game extracts maps next to the executable and starts.

On Linux without the desktop portal or zenity, the game can't show a file picker. It tells you to put the disc image next to the executable and stops, so do that and start it again.

Arch-based distributions can install the opence-bin package from the AUR instead.

Settings

Settings live in config.toml next to the game. Most of them are in the menus too, including FOV, anti-aliasing, frame rate limit and the high-res HUD.

Keep the maps folder Xbox-only

maps holds the Xbox maps from your disc. If you copy a Halo PC or Custom Edition maps folder over it, the game will say so and stop. Custom Edition maps go in their own folder: see the Custom Edition maps guide.
